It would be interesting to see the K9AY with a preamp set to give the same 
"gain" as a Beverage added to those signal reports in the future.

Since the Beverage is a non resonant piece of wire Im curious how close it 
can be to those verticals? Since the verticals have little signal at about 
7* and lower according to the article and probably much higher over poor 
ground will a close Beverage wire have any effect?

I have room for either system but not both unless I go into a neighbors 
woods behind me and run a 1000' feedline. They are OK with 2 reversible 
Beverages going 400' and 600' beyond my property but may not approve of a 
320' circle with a fair amount of trees removed no matter how poor (the 
trees) and scruffy they are.

If I remained on my property at least 3 Beverages would be inside the 
vertical circle and they could be dropped to 3-4' above ground. RF ground is 
almost non existent here as bedrock is only a few feet down.
