I seem to recall reading on this reflector that it is possible to find multiple resonant points on a single antenna. Measuring my shortened 160m vertical, I find resonances at every now and all the w

If your antenna is properly fed with a good balun, you'd get resonances on odd harmonics with SWR generally increasing with frequency due to increasing radiation resistance. This implies that both r

_________________________________________________________ This is normal behavior for nearly all antennas. A simple half-wave dipole is resonant at its fundamental frequency and also at all of the od
