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.
