[TowerTalk] Beverage Antenna Mounted 12' Above Gorund

[David Gilbert]

Since actual RF ground could be almost anywhere (and could be definitive 
or graded) depending upon your soil, practically speaking the difference 
between 12' and 10' is a meaningless distinction.

The height above actual ground will of course moderately affect the 
input impedance, but you're not going to know what that is ahead of time 
and to be rigorous you would want to adjust the terminating resistance 
for a more or less constant impedance as a function of frequency ... and 
then set the turns ratio of the coupling transformer to match.

Personally, I think being THAT rigorous isn't all that rational. Put 
your wire at 12' and use whatever input transformer and termination you 
already planned.
