    4-Stack Dipole Arrays

    VHF Mid-Band 66…87,5 MHz

    ★ FDC four-stack dipole arrays consist of centre-fed, broadband,


    half-wave antennas fully equipped with mounting booms and
    clamps.
    ★ By vertically stacking these antennas, the width of the vertical
    beam is minimised while the width of the horizontal beam
    remains unchanged.
    ★ This configuration results in a 6 dB gain.
