[TowerTalk] Beverage Antenna Mounted 12' Above Gorund

[David Gilbert]

I could certainly believe that to be the case.  If your ground 
conditions are such that the effective reference is not near the 
surface, lower is probably better since a Beverage high off the ground 
is just an end fed long wire.  As Jim and others have pointed out, a 
true Beverage needs reasonable proximity to lossy soil to work properly.

My soil here on this rocky southern Arizona hillside is normally bone 
dry, and I suspect (can't prove it though) that my BOG works as well as 
if I had it higher off the ground.  I've adjusted the terminating 
resistor until I got a constant feed impedance versus frequency (i.e., a 
flat line) and it's roughly 400 ohms ... not much different than the 
generally accepted value for a standard beverage.

73,
