Steve - I have a similar setup as Arie - an 80 meter Inverted L at 40 feet for my transmitting antenna and a Hustler 5BTV vertical ground mounted about 10 feet from being directly under the vertical. Works fine. If I crank up my KPA500, the relays in the K3 quickly isolate the subrx from too much RF.
