Asked JK why he used the manufacturers antenna, in lieu of the base-loaded types. The mount requires a 3/4" hole to be drilled into an exterior panel with a three hole bolt circle. 7 m above ground level (AGL), and the apex is about 11 m AGL. 160- and 80-Meter Matching Network for your 43-foot Vertical - UPDATED Phil Salas – AD5X The popular 43-foot vertical is self supporting, not too obtrusive, and has higher radiation resistance than many popular trapped- or loaded verticals (increased radiation resistance minimizes efficiency-robbing ground losses). The loaded dipole (V2) is not as good as a full size antenna but it can be used in limited spaces and even indoors. receiving, the currents induced on the antenna by the passing EM field cause a terminal voltage at the feedpoint of the antenna, which generates a propagating signal down the coax to the receiver's input amplifier circuit. 625) Complete Cut Chart *Caution, this antenna looks very similar to our legacy No Ground Plane Antenna.
