Default How much voltage on a vertical?


"Bob Glenn" wrote in message

On a typical 25 watt 2 meter setup, how much voltage would there be on
the end of a 1/4 antenna?


==============================

25 watts into a 1/4-wave vertical antenna on 2 meters -

Base current about 0.82 amps into 37 ohms,

Volts about 160, measured (if you can) at top of antenna across about 1000
ohms.

Things vary slowly with length-to-diameter ratio of the antenna conductor.

As conductor diameter increases, volts at the end tend to decrease.
