[TowerTalk] Beverage Antenna Mounted 12' Above Gorund

[Richard (Rick) Karlquist]

Besides the 2 ft vs 10 foot A/B tests, I did some BOG tests.
The signal out is quite low, but they did work OK and I think
would be valuable in case I had to run a "stealth" beverage.
I have 20 acres so I fortunately don't need to resort to that.
I used 2 ft mainly just to keep them out of the weeds.

BTW, my soil is highly conductive (15 to 30 mS).
