Introduction
Congratulations on obtaining your DX Engineering DXE-160VA-1 Monoband Vertical Antenna!
Now you can have a high-performance vertical antenna specifically for the 160 meter band.
Achieve the strongest possible presence at your power level and be competitive!

The 160 meter band vertical antenna is tunable with an impressive 40 kHz bandwidth. This means
that operation on the CW DX frequencies and DX Phone frequencies is within range of most radio
internal tuners - no antenna changes are necessary.

A custom designed capacity hat system allows this vertical monoband antenna to get on 160 meters
with unparalleled success in in antenna that is only 55 feet tall.

The DX Engineering DXE-160VA-1 is a slow taper 55-foot high Monoband Vertical Antenna
system. The vertical antenna is specifically designed to operate on 160 meters. Included with this
antenna system is a patented rugged stainless steel pivot fixture (US Patent No. 8,130,168) for ease
of assembly and adjustments. Engineered with 6061-T8 and 6063-T832 corrosion-resistant
aluminum tubing, stainless steel mounting brackets and stainless steel hardware, this antenna is very
durable and attractive.

Why Does This Antenna Perform So Well for Its Height?

The top-hat is large enough that the current along the radiator is almost constant. Typical
shortened verticals for this band, with smaller top-hats have currents that vary along the length
and end up producing much less signal strength. This also works in the receive mode to let you
hear weaker signals although at this frequency range Dedicated Receiving Antennas [see
http://www.dxengineering.com/default.asp?DeptID=12] are almost a must.

The optional DXE-VRW-1 Manual Winch for easy one-person raising and lowering of the antenna
is available from DX Engineering. You can move the DXE-VRW-1 winch between similar
antennas in a multi-antenna installation.

This antenna system requires a heavy duty mounting pipe. Recommended installation should
provide up to 3" OD heavy wall galvanized steel pipe set in concrete. Schedule 80 pipe that is called

-2-
2-1/2" has an outside diameter of 2.875" is recommended. 36" of the mounting pipe should extend
above ground level. Depth of the mounting hole and amount of concrete is dependent on local soil
type, condition and antenna guying.

WARNING!
INSTALLATION OF ANY ANTENNA NEAR POWER LINES IS DANGEROUS

Warning: Do not locate the antenna near overhead power lines or other electric light or power
circuits, or where it can come into contact with such circuits. When installing the antenna, take
extreme care not to come into contact with such circuits, because they may cause serious injury or
death.

Overhead Power Line Safety

Before you begin working, check carefully for overhead power lines in the area you will be
working. Don't assume that wires are telephone or cable lines: check with your electric utility for
advice. Although overhead power lines may appear to be insulated, often these coverings are
intended only to protect metal wires from weather conditions and may not protect you from electric
shock

Keep your distance! Remember the 10-foot rule: When carrying and using ladders and other long
tools, keep them at least 10 feet away from all overhead lines - including any lines from the power
pole to your home.

Tools Required
Two 9/16" wrenches, (one of them should be open-end)
One 7/16" open end wrench
Two 3/4" wrenches
Medium size flat blade screwdriver or 5/16" nut driver for the element clamps
Small Phillips Head screwdriver for coil taps
Tape measure
Felt-tip marker
Soldering Iron and Solder
Knife for cutting guy ropes

Manual Updates and Information

Every effort is made to supply the latest manual revision with each product. Occasionally a manual
will be updated between the time your DX Engineering product is shipped and when you receive it.

-3-
Please check the DX Engineering web site (www.dxengineering.com) for the latest revision manual.
Please - Take the time to read the entire manual before you start assembly. There are plenty of
pictures and drawings to see, and if you read the entire manual first, you'll get a better feel for the
overall construction methods described. Assembly is not difficult, but there are a number of parts
that must go together in a certain sequence to make assembly easier.

Installation Sequence
1. Site Selection
2. Mounting Pipe
3. Coaxial Cable to Mounting Pipe
4. Radial System
5. Pivot Base Assembly (Patented)
6. Antenna Assembly
7. Base Series & Shunt Coil Assembly
8. Capacity Hat assembly
9. Guying
10. Tuning

Site Selection
Select a mounting location clear from power lines, structures and other antennas by a minimum of
65 feet (55 + 10 ft. safety rule). Consider overhead power lines, utility cables and wires. The
further away the vertical is mounted from local noise sources or other metallic objects, which can
re-radiate noise and affect the tuning, radiation pattern and SWR, the better. Determine the direction
you want the antenna to pivot and make sure there is adequate clearance (at least 65 feet).

Mounting Pipe
Use a customer supplied 2-1/2" schedule 80, which has an outside diameter (OD) of 2.895",
galvanized steel thick-walled mounting pipe at least 7-1/2 feet long. This will allow approximately
4-1/2 feet below ground and 36 inches above ground.

Some manufacturers use the term DOM (drawn over mandrel) which will give you a true OD
dimension. Other types of mounting pipe may be used but due to lateral strength needed ensure the
mounting pipe is strong enough. The material most available is ASTM A513 Type 5 which is a
1020 material. Some pipe suppliers list the material as either 1020 or 1026. Type 1020 has the
following properties:

ASTM A513 (1020): Up to 2-3/4" OD with maximum wall thickness of 0.25"

Tensile: 80,000 PSI. Yield: 70,000 PSI. Elongation in 2": 15%. Rockwell Hardness: B80

ASTM A513 (1020): Over 2-3/4" OD with wall thickness heavier than 0.25"
Tensile: 70,000 PSI. Yield: 60,000 PSI. Elongation in 2": 20%. Rockwell Hardness: B80

3.00" OD x 0.25" wall thickness (or more) of 65,000 PSI yield tubing may also be used.

-4-
Depending on your geographic location, various dealers should be able to supply the mounting post
you specify. The following dealers can supply DOM tubing: (Other dealers in your area may be a
better choice.)

On Line Metal Store: www.onlinemetals.com Speedy Metals: www.speedymetals.com

Metals Depot: www.metalsdepot.com

Note: DX Engineering does not recommend or endorse any specific vendor.

This mounting pipe must be permanently mounted in the ground, preferably in a concrete base 2
feet by 2 feet by 4 feet deep (with gravel below for drainage). The antenna system requires this type
of mounting to help withstand the lateral forces present on the
antenna during wind conditions and when operating the pivot
function. Make the hole deep enough to accommodate at least 4
feet of pipe and 4 to 6 inches of gravel at the bottom for
drainage. Set the mounting pipe on the gravel, use the concrete
to fill around the pipe per the concrete instructions. Fill the hole
until the concrete is level with the ground around it. Use a level
on the mounting pipe as you fill the hole to be sure the mounting
pipe is vertically straight.

Your location, landscape and ground conditions may require

different mounting solutions in order to have the steel mounting
pipe and the vertical antenna in a secure position.

Note: Galvanized steel, rather than aluminum, is much

more suitable for mounting in concrete. Aluminum
will quickly corrode due to incompatibility with the
materials used to make concrete.

Coaxial Cable to Mounting Pipe

The coaxial cable should be routed to the base of the antenna system and be buried below the radial
system. PVC Conduit pipe may be used to house the coaxial cable. Bury the cable 6" to 12" below
ground level.

-5-
Radial System
The use of a radial system is a key requirement for a high performance quarter wave vertical
antenna system. With a vertical antenna system, the radials are the second half of the antenna. The
radials contribute to the radiation efficiency of the entire vertical antenna system.

At a minimum, 32 radials, each 65 feet long, should be used with this antenna. Longer radial wires,
up to 135 feet each, would provide an improvement in signal strength for this 160 meter antenna.
DXE-RADW Radial Wire, a 14 gauge stranded copper with black relaxed PVC insulation wire is
suggested for the best results. The wire radials should placed as symmetrically as possible straight
from the feedpoint around the vertical antenna and spaced evenly, regardless of how many radials
are used. Do not cross or bunch any radial wires as this nullifies their
effectiveness. If you have limited space, put in as many straight radials
as you can. The radials must be connected to the shield of your
feedline. The patented DXE-RADP-3 Stainless Steel Radial Plate is
an ideal optional item which provides an excellent system for attaching
radial wires to your vertical antenna system.

Radial wires can be laid on the roots of the grass using DXE-STPL
Radial Wire Anchor Pins to hold them down. Using enough staples
will ensure the wires will not be snagged by mowers, people, or
animals. Grass will quickly overgrow the radials and it will be virtually
impossible to see them. An article describing this process is available
on the DX Engineering website in the Tech Info section. Radials can also be buried just under the
surface by using a power edger to make a slit in the soil.

Assembly Notes

Note: DXE-P8A Penetrox A Anti-Oxidant should be used between all antenna element
sections. Penetrox A is an electrical joint compound to affect a substantial
electrical connection between metal parts such as telescoping aluminum tubing or
other antenna pieces. It ensures high conductivity at all voltage levels by displacing
moisture and preventing corrosion or oxidation.

Note: UMI-81343 Never-Seez or DXE-NSBT8 Anti-Seize should be used on all clamps,

bolts and stainless steel threaded hardware to prevent galling and to ensure proper
tightening.

Note: The following assembly instructions are based on using a customer supplied
2.895" OD Mounting Pipe, with the optional DXE-VR-1 Manual Winch,
optional patented DXE-RADP-3 Radial Plate and the optional DXE-363-SST
Bulkhead Connector.

-6-
Radial Plate to Mounting Pipe
Place the optional DXE-RADP-3
Radial Plate over the 2.895" OD
mounting pipe (3 OD maximum).
Connections to the antenna will be
made via the optional DXE-363-SST
bulkhead fitting SO-239 socket
connector. The DXE-RADP-3 Radial
Plate comes with 20 sets of stainless
steel hardware for mounting the
radial wires. It is suggested that 32
radials each 65 feet long be used.
Longer radial wires, up to 135 feet
each, would provide an improvement
in signal strength for this 160 meter
antenna. Additional DXE-RADP-
1HWK Radial Plate Wire Optional DXE-RADP-3 Radial Plate Mounted to
Attachment Hardware Kits a 3" OD Mounting Pipe
will be required.

Attaching Ground Radial Wires to the Radial Plate

Using the 20 sets of supplied 1/4" stainless steel hardware (Bolt, Star Washer, Flat Washer, Split
Washer, Nut) connect the optional ground radial wires to the DXE-RADP-3 Radial Plate as shown
below. Additional hardware kits are available (DXE-RADP-1HWK) that contain 20 sets of Radial
Plate Hardware.

There are optional DX Engineering Radial Wire Kits available. DXE-RADW-500K/BD contains a
500 foot spool of 14 gauge copper stranded wire with black PVC insulation, 20 Terminal Lugs and
100 Steel or Biodegradable Lawn Staples. The DXE-RADW-1000K/BD Radial Wire Kit contains
a 1,000 foot spool of 14 gauge copper stranded wire with black PVC insulation, 40 Terminal Lugs
and 200 Steel or Biodegradable Lawn Staples. RADW-65RT contains 20 each 65 foot radial wires
with 1/4" terminal attached.

Depending on the number of radial wires used, space them out evenly around the Radial Plate. The
Radial Plate will accommodate up to 60 radial wires (60 laser drilled holes), or up to 120 radials if
doubled up.

7. To lower the antenna, ensure the winch hook is in the Antenna Hook Mount and the winch is
wound up snug so the antenna will not move. Remove the four bolts and hardware that hold the
Pivot Lock Plate to the Pivot Base Winch Mount Plate. You can now use the winch to pivot the
antenna downward.

Four Bolts to be removed to allow for pivoting

8. Turn the crank on the manual winch to lower, or raise the antenna. After raising the antenna
completely, make sure you replace the four bolts that were removed in step 3. The manual
winch should be removed when not in use to protect the gears and web strap from weather and
environmental effects.

Note: Sawhorses, chairs, or ladders should be used to support the vertical sections during
assembly with the pivot base and whenever the vertical is tilted down to allow easy
maintenance, or when making adjustments.

General Information about Aluminum Tubing

Note: DXE-P8A -Penetrox A Anti-Oxidant should be used between all antenna element
sections. Penetrox A is an electrical joint compound to affect a substantial electrical
connection between metal parts such as telescoping aluminum tubing or other antenna
pieces. It ensures high conductivity at all voltage levels by displacing moisture and
preventing corrosion or oxidation
Note: UMI-81343 Never-Seez or DXE-NSBT8 Anti-Seize should be used on all clamps,
bolts and stainless steel threaded hardware to prevent galling and to ensure proper
tightening.

When assembling any telescoping aluminum tubing sections you should take the following steps:

1. Make sure the edges are smooth and not sharp. Deburring may be necessary, since burrs and
shavings can occur on seams as well as edges. All surfaces need to be completely smooth to
allow easy assembly of tubing sections.

Caution
Aluminum tubing edges can be very sharp.
Take precautions to ensure you do not get accidentally cut.

The raised particles and shavings that appear when the aluminum tubing is machined are
referred to as burrs, and the process by which they are removed is known as deburring.
Deburring is a finishing method used in manufacturing. Our aluminum tubing is machine cut on
both ends and may have machine slits on one end. Although DX Engineering manufactured
aluminum tubing is deburred, you should further assure that there are no ragged edges or
protrusions.
Use the DXE-22166 Slim Grip Deburring Tool, or the DXE-22600 Deburring Tool with
Extending Handle and Extra Blades for this operation.
2. Clean the inside of the aluminum tubing to clear out any dirt or foreign material that would
cause the aluminum tubing sections to bind during assembly. Do not use any type of oil or
general lubricant between the aluminum tubing sections. Oils or general lubricants can cause
poor electrical connections for radio frequencies.
3. Clean the outside of the aluminum tubing to clear any dirt or foreign material that would cause
the clamps to malfunction during assembly.
4. The use of DXE-P8A Penetrox A is highly recommended. Penetrox A is an electrical joint
compound which effects a substantial electrical connection between metal parts such as
telescoping aluminum tubing or other antenna pieces. Using Penetrox A assures high
conductivity at all voltage levels by displacing moisture and preventing corrosion or oxidation.
5. When assembling the aluminum tubing sections, ensure the area is clear of grass, dirt or other
foreign material that could cause problems during assembly of the closely fitted telescoping
sections.

Assembling the Vertical Sections
The vertical sections of the DXE-160VA-1 is made of custom engineered 6061-T8 and 6063-T832
corrosion-resistant aluminum tubing ranging in size from 3" OD to 1" OD. The 3" OD section has
already been mounted in the Pivot Base Assembly in an earlier assembly step.

Topping off the installation of the vertical sections will be the Capacity Hat assembly which is
specifically designed to allow the center of resonance to be moved down to the low band edge of
160 meters for dedicated CW ops.

It is suggested that the

vertical elements be laid
out in a line according
to size on a flat surface
for ease of assembly.
Once all the parts are
assembled, the vertical
sections should be
supported with either
saw horses, chairs or
other suitable structures
for installation of the
capacity hat.

When all the vertical

element sections are
assembled, they will be
mated to the Pivot Base
Assembly.

The 3" OD element which is

already mounted on the base
pivot assembly is shown for
reference. The 3-1/2 bolts
and hardware will be used
in a later step (page 26).

- 20 -
3. Assemble the 2.5" OD element to the 2.75" OD element using the two stainless steel 3-1/4" long
1/4" bolts, four stainless steel flat washers and two 1/4" stainless steel Nyloc nuts as shown
below. Make sure you insert the 2.5 OD tube into the correct end of the 2.75 OD section - the
holes at each end are drilled differently. When tightening the bolt and Nyloc nut, tighten them
enough to hold, but not tight enough to deform the aluminum elements.

The following drilled sections are drilled to match the next size, so make sure you have the correct
ends matched up (holes aligned).

4. Repeat the above step to mate the 2.5" OD element to the 2.25" OD element using the 3" long
1/4" bolts and hardware.

5. Repeat the above step to mate the 2.25" OD element to the 2" OD element using the 2-3/4" long
1/4" bolts and hardware.

- 21 -
6. Using a tape measure and felt tip pen, mark a line 4 (on the end opposite the slits) on the 72
long tubes (1.125, 1.25, 1.5 and 1.75 OD tubes) and 12 on the 1 OD Tube. Note the 1.5
OD tube has slits on both ends so it does not matter which end you mark.

7. The five slit element tubes are installed using Stainless Steel Element Clamps. The drawing
below shows the exposed lengths for reference.

- 22 -
The reference drawing below shows the hardware used for joining the element tubes.

8. Locate two DXE-ECL-24SS Stainless Steel Element Clamps, one DXE-ECL-20SS Stainless
Steel Element Clamp and the 1.75" OD x 72" element tube that was marked in step 7.

Slide the two DXE-ECL-24SS element clamps over the 2" OD element. Slide the one DXE-
ECL-20SS element clamp over the 1.75" OD element. Slide the 1.75" OD element inside the 2"
OD element tube to the mark made at 4". Tighten the two DXE-ECL-24SS clamps in place. Do
not over-tighten which may cause clamp damage. This element tubing joint uses a second clamp
to ensure proper element position. Slide the DXE-ECL-20SS next to the joint between the 2"
OD element tube and 1.75" OD element tube. Tighten the clamp in place. This third clamp
ensures that the 1.75" section cannot slip further inside the 2" OD section.

9. Locate the Guy Ring, two DXE-ECL-20SS Stainless Steel Element Clamps, one DXE-ECL-
16SS Stainless Steel Element Clamp and the 1.5" OD x 72 long element.

Mating the Vertical Element to the Pivot Base Assembly
1. To lower the antenna, ensure the winch hook is in the Antenna Hook Mount. Remove the four
bolts and hardware that hold the Pivot Lock Plate to the Pivot Base Winch Mount Plate. You
can now use the winch to pivot the antenna downward.

Four Bolts to be removed to allow for pivoting

2. Locate the 3-1/2" long 1/4" bolts,

four stainless steel flat washers
and two 1/4" stainless steel
Nyloc nuts. Align the 3" OD base
section element with the
assembled vertical elements.
Slide the 2.75" element section
into the 3" OD base element
section aligning the 4 holes.

- 26 -
3. Assemble the 2.75" OD element tube to the 3" OD element tube (installed on the Extren
insulated channel) using the two stainless steel 3-1/2" long 1/4" bolts, four stainless steel flat
washers and two 1/4" stainless steel Nyloc nuts as shown below. When tightening the bolt and
Nyloc nut, tighten them enough to hold, but not tight enough to deform the aluminum elements.

DANGER: When raising or lowering the vertical antenna make sure you have
not inadvertently located the antenna underneath or near power lines.
Residential power lines are often less than 40' high.
Contact with any power or utility lines Can Be Lethal !

In areas where there is a high atmospheric static condition (areas prone to precipitation or snow
static) this antenna (as with all antennas) will build up a static charge. When working on the
antenna, especially in the raised position, you may want to ground the antenna to bleed off any
static before touching the antenna. (Obviously, you also do not want RF present on the antenna
when touching it). When installed, the base series and shut coils (described below) will act as a
constant static bleed for your vertical antenna in areas where precipitation static or snow static is
present.

When the vertical elements are all connected together, the overall total length measured from the
bottom of the 3 OD base element to the top of the capacity hat assembly will be approximately 55
feet in length.

Base Series and Shunt Coil Assembly and Installation
Two coils are used at the base of the antenna. One coil is in series with the antenna feed point; the
other coil is shunt coil and is connected to the Radial Plate. Attach the series coil with the straight
bracket on the antenna feedpoint using the hardware as shown.

Install the shunt coil with the L bracket to the radial plate on top of an existing radial wire bolt
using the hardware as shown below. The wire (with terminals) is connected from one end of the
series coil to the shunt coil (top connection). At this same connection point the wire with the PL-
259 on the other end, is connected to this same point.

Position the shunt coil on the Radial Plate to allow the wire to connect to the series coil and not
interfere when pivoting the antenna.

Capacity Hat Information
The capacity hat is made up of special mounting hardware at the top of the antenna. The capacity
hat uses four 39 foot 14 gage wires coming from the top of the antenna in a four sided pyramid
shape connected to four 24 foot 14 gage wires at the base of the pyramid. The bottom joints of the
capacity hat (the pyramid) will then be guyed using the included rope to the guy points that are 55
feet from the antenna base.

Capacity Hat Assembly
1. Locate the eight wires for the capacity hat. Four wires are 39 feet in length. Four wires are 24
feet in length. Ring Terminals are installed on the ends of the wires.

2. Gather the other parts required for the Capacity Hat assembly.

3. If not already done, insert the fiberglass tube into the aluminum tube making sure the drilled
holes are aligned.

- 31 -
Notes on the capacity hat assembly:

Two threaded rods are installed (centered) in the drilled holes.

Each side of the threaded rod will get one of the 39 foot wires with ring terminal and be held
in place using an external tooth washer and a stainless steel hex nut as shown.

Aluminum spacers are pressed into the patented insulators as shown.

Note the positioning of the patented insulators (look carefully for cupped area).

Prior to installing the four patented insulators on the two threaded rods, one end of the 39
foot wires will be routed through the patented insulators.

The following pictures detail the assembly of the capacity hat assembly

3. Using the four patented insulators, 10-24 x 3/4 hex bolts, #10 external star washers, #10 flat
washers and the 10-24 Nyloc hex nuts, join the 39 foot wires coming from the capacity hat
assembly with the 24 foot wires together as shown below.

Note the way the three wires are woven through the insulator in the following photographs.

Refer to the overhead picture on the previous page for an overall picture of how the capacity hat
should look when assembled.

- 38 -
No Slip Knots
No slip knots are the most efficient way to securely tie ropes for antennas. The following diagram
shows the steps to make a good no slip knot.

Guy Rope Installation

Guy ropes are made from the 500 foot spool of rope included with this antenna. Two sets of four
ropes are installed. One set of four 20 8 ropes are connected to the antenna at the guy ring using
carabineers and connected at the other end at the lower insulators (connecting the capacity hat wires
together). The other set of four 46 guy ropes are connected to the lower four insulators (connecting
the capacity hat wires together) and go to the four optional earth anchors.

It is suggested that these ropes be anchored in the ground 55 feet away from the base of the antenna
using the optional DXE-EA15-4P Earth Anchors available from DX Engineering. Your soil
conditions may require different guying scheme. The DX Engineering anchors may not be suitable
for real loose sandy soil or rock.

Cut four ropes at 48 feet each, and four ropes at 23 feet each. This allows about 1-1/2 feet on each
end for looping and tying knots.

Using the four Carabineers, tie one end of the four 23 foot ropes using a no slip knot.

The four Carabineers are then attached to the Guy Ring. The Carabineers open when pushed.

- 39 -
 Note the four holes used on the guy ring.

Guy Ring Guy Ring mounted on antenna Carabineer open

Four 46 foot ropes are attached to the four insulators used for the bottom of the capacity hat. The
four 23 foot ropes are also attached to the four insulators and when tied should be 20 8 long.

Adjustments should be made to align the guy ropes in the manner that allows you to raise and lower
the antenna by only removing one set of guys from the earth anchors. DXE-EA15-4P Earth
Anchors work very well for most installations and are available from DX Engineering. Tie the loose
ends of the four 46 foot ropes at four points 55 feet from the antenna. See the diagram on the next
page for details. The ropes should be snug, but not overly tight. The four ropes going from the earth
anchors to the capacity hat keep the wires properly spaced from the vertical antenna and the four
ropes going to the guy ring give the antenna stability. By adjusting the position of the Capacity Hat
and Guy Ring to have the ropes as shown below, only one set of guys needs to be loosened from
one earth anchor when pivoting the antenna.

Tuning
Tuning Hints
According to prior instructions, assemble and erect antenna, radial plate, radials and top hat and
then the two tuning coils (series and shunt) to the base of antenna and radial plate. Raise the
antenna.

Staying at least fifty feet from the base of the antenna (using at least a 50 piece of low loss coax
such as RG-213U) set up to use either an antenna analyzer or an HF radio as an SWR indicator.
A fifty foot RG-213U with PL-259 connectors installed is available from DX Engineering as part
number DXE-213UDU050.

In some areas, due to the signal capture ability of this antenna at low frequencies and the close
proximity of AM Broadcast Stations some Antenna Analyzers such as the MFJ-269 or others of
similar design may not be able to be used. It will be necessary to use a normal HF rig with an SWR
indicator. We have used both methods and the results are the same.

To determine if your location is near AM broadcast stations which may interfere, go to this website
and enter your location: Using your zip code: http://radio-locator.com/

Using Longitude and Latitude information - http://radio-locator.com/cgi-bin/locate?select=lonlat

Naturally, using your Longitude and Latitude information [which can be obtained on your qrz.com
page] is MUCH more accurate.

Tuning Procedure
Place the SWR coil tap clip-lead in the middle of the Shunt Coil (the coil mounted to the Radial
Plate on the L bracket).

Short out the Series Coil (the coil mounted to the antenna feedpoint with the straight bracket)
completely with the coil tap clip-lead provided.

- 42 -
Look for the lowest SWR on the Radio or Analyzer. A typical reading would be: Approximately
1.4:1 SWR at approximately 1.885 MHz. If you dont see an SWR dip look higher or lower in
frequency and adjust the top hat and length of the vertical to get the SWR dip approximately as
shown in the SWR graph on the next page.

Move the shorting lead on the Series Coil to about the middle turn. A typical reading would now be
approximately 1.5:1 SWR at approximately 1.800 MHz

To raise the Resonant Frequency, adjust the Series Coil shorting lead to short out more of the coil.

To lower the Resonant Frequency, adjust the Series Coil shorting lead to short out less of the coil.

Adjust the Shunt Coil to achieve the lowest

SWR. This may cause the Resonant
Frequency to change slightly since the 2 coils
interact somewhat.

Readjust the Series Coil to arrive at the

frequency where you wish to have the lowest
SWR.

A typical final reading will be approximately

1.2:1 SWR at 1.824 MHz.

Once final tuning is complete and you have

verified correct operation on-the-air, the coil
taps can be soldered in place to eliminate any
future intermittent connections due to
environmental corrosion to the coil taps and
coil wire connections.

Typical
SWR
Graph

- 43 -
The antenna exhibits more than a 40 kHz wide 2:1 SWR Bandwidth as shown in the graph above
which is a screen shot from a calibrated Agilent 8714ET Network Analyzer.

Using an Icom IC-718 Radio with an internal tuner DX Engineering Design and Test Engineers
were able to reduce the SWR at the 2:1 points down to 1:1 easily. This will extend the use of the
antenna significantly beyond the 2:1 points shown above. Almost any radio with a built in tuner -
and certainly with an external tuner of any reasonable ability - will be able to do the same.

The adjustment of the Series Coil and the top-hat will allow wide excursions inside and slightly
above and below the 160 meter band, if desired. DX Engineering will not be able to supply detailed
instructions for this but basic antenna principles will apply: A larger top-hat or use of more of the
Series Coil will lower the frequency whereas a smaller top-hat or using less of the Series Coil will
raise the frequency. The adjustment of the Shunt Coil will reduce the SWR.

Locking the Pivot Base

To help prevent accidental pivoting, ensure the four pivot locking
bolts are in place and properly secured. Additionally, you may replace
one of the bolts with a padlock to further prevent tampering or
accidental pivoting as shown below.

Ensure all four Pivot Locking Bolts are in place

the wire, squeeze the handle, and listen for the click. Thats the sound of another perfect wire stripping job performed in about 2
seconds- a fraction of the time it takes your pocket knife to do the same job. An adjustable wire length guide helps
you make uniform strips, and a built-in wire cutter and crimper helps you complete your wiring job.
