Topband: FCP Folded Counterpoise

[Jim Bennett]

Mike - FWIW - I had a two tuned-radial 80 meter Inverted L hung in one of our redwood trees. Replaced it with an FCP and my bandwidth was almost the same. Quite happy with the FCP at this QTH. We aren't supposed to have any ham antennas outside, but being able to string the FCP towards the top of the fence line, and only a bit longer than 30 feet has made my 80 meter operating lots more interesting.
