Todd If you are interested in experimenting, you could try a K2AV folded counterpoise under that inverted L. If installed as recommended, it will provide a decent counterpoise system. One advantage to the FCP is that it is possible to also end fed the system, should that be a requirement.
I was using an inverted L against a tower with random grounding--antenna R was up in the 80 ohm range. Over the K2AV, and away from the tower the antenna R dropped to 26 ohms. It works good enough for now. I have very poor ground conductivity, and running a large radial field would be hard over rocky sandy soil. I also fed the L over the FCP for 80 meters, an L Network is switched in to match the antenna, and the FCP counterpoise is changed over to 80 meters using surplus Russian vacuum relays. _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
