LB, W4RNL was giving advice on traped dipole for 160m and 80m and sugests using
trap on 3.4 MHz in order to equalize the gain. It sounds to me as M$ science.
One can hardly expect shortened 160m dipole on half the wavelength height to be
as good as full size 80m dipole so we simply make trap a poor isolator and
dimish the gain. The importance of the "same" traps regardless of the resonant
frequency beats the laws of physics but may fit some simulation programs.
