Abstract
An apparatus and method for exciting an antenna with dual frequency bands which comprises feeding a first channel of the antenna with a first signal in the VHF band such that a first current is established in a first direction resulting in a first polarization, feeding a second channel of the antenna with a second signal such that a second current is established in a second direction resulting in a second polarization, and isolating characteristics of the first channel from characteristics of the second channel and the characteristics of the second channel from the characteristics of the first channel such that both the first channel and the second channel are adapted to transmit and receive energy within the same antenna structure without appreciable coupling between the first channel and the second channel.
