[TowerTalk] Multiband antenna with non-resonant trap

[Hans Hammarquist]

This might be the wrong forum but does anyone remember an article in QST (or maybe QEX) of how to make multibands antennas using LC traps where the traps resonance frequency is not at the operating frequencies. By putting an LC circuit somewhere in or close to the center of a vertical you get two resonances, one where the C-part act and increase the resonance and one where the L-part decreases the resonance frequency.


Anyone?
