I have one of the early PAR end-fed 20M antennas, for 20 watts, I think. I've only used it for field work backpacking with my Elecraft K-1, but it worked great. I'm looking at those now.

Tell me more about the folded dipole, how high do you have it up, and can you work top band with it? I would think it would suck for QRP, but everything else would be OK, actually, broadbanded and quiet?

Actually, best for me if I can get some aluminum up might be a roll my own 80-40-30 parallel dipole?
