NOTE: When sweeping waveguide on the drum, a sliding load must be inserted
into the open end of the waveguide to form a temporary termination
(simulation of the antenna).

Conversion Formulas
Return Loss: RL = −20log(ïΓï)
Reflection Coefficient: ïΓï = (VSWR − 1) ⁄ (VSWR + 1)
Voltage Standing Wave Ratio: VSWR = (1+ïΓï) ⁄ (1−ïΓï)
