Patent ID: 7050018

Claim:
A multi-band antenna system comprising: a) At least a pair of spatially somewhat parallel radiating conductors fitted with a plurality of relays arranged along the length of said radiating conductors in a way that allows the effective length of said parallel radiating conductors to be changed by the action of the contacts of said relays, b) a first means of electrically isolating said pair of parallel radiating conductors in order that direct current and low frequency control signal voltages may exist between them, c) a second means of extracting power and control signals from said parallel radiating conductors in order to activate said relays in accordance with electrical signals from a remotely located controller, d) a third means of electrically connecting said pair of parallel radiating conductors together at high frequencies allowing said parallel radiating conductors to act as a single radiating conductor, e) a fourth means of conducting direct current power and control signals to said relays from said controller through the antenna feed line conductors and the said parallel radiating conductors without interference to or from the radio frequency signals utilizing the same conductors.
