Abstract: A vertical antenna which is omnidirectional and includes completely automatic band switching for the amateur radio frequencies of, eighty/seventy-five meters, forty meters, twenty meters, fifteen meters, and ten meters. The vertical antenna has a low angle of radiation and a low standing wave ratio on all frequencies which provides for direct coaxial cable transmission line feed. The eighty-meter and forty-meter resonator capacitor sections provide inductive reactance for operation on eighty/seventy five meters and forty meters while permitting simultaneous resonance on each of the three higher frequencies of twenty, fifteen, and ten meters. The entire radiator length of the vertical antenna is active on all frequencies except for fifteen meters where the upper portion of the antenna is decoupled above an end of a fifteen-meter quarter-wave decoupling stub in a first embodiment. The entire radiator length of the vertical antenna is active on all frequencies in a second embodiment.
