[Milsurplus] Tuning the ART-13/BC-348

Considering the HF frequencies aircraft usually
use then and today, the outside fixed wire never
aproaches a quarter-wave long.  Ergo a very high
voltage feed point.  The only Low-Z antenna I've
encountered is when the trailing wire is run out
to Max antenna Current right out of the transmitter.
Maybe that's 70 Volts or thereabouts.

War Story Follows:  Once when I operated a BC-191
on LF as a beacon the antenna wire wasn't not very
long, so there was a high voltage at the antenna
tuner.  I could light my cigarette by pushing a
1 1/2 wire into it, and holding it up to the antenna
binding post with a wood stick.
