proof qrp works.
True enough, I have a 80 M coax fed dipole that tunes right up on 160 meters. Doesn't radiate with a damn but hey the radio sees a 1:1 SWR.
6 meter 3 element beam will load on 20 meters too!
Hey I have made contacts on my old Heathkit Cantenna that is sitting on the basement floor and that thing has a 1:1 SWR on all bands.
