The new end fed Zepp that I put up last weekend seems to be doing a good job for itself. I haven't gotten what I would consider a decent signal report from the States, yet; but DX has been A-OK!
So far I've worked Romania, Finland and St. Vincent with it, all on 30 Meters and all with QRP power levels. It seems to favor locations off the ends; so in this case NorthEast (which would beam into Europe) and to the SouthWest.
I haven't added any counterpoises. There seems to be no problems with stray RF getting into the shack. I think it'll be okay for 30 Meters.
