A telescopic antenna assembly provides pairs of arms (210, 220, 230 and 240) on an elongated dielectric tube (260). A hot conductor (273) and a ground conductor (275) of a group of exciters couple energy between the arms and a feed line (250). The hot and ground conductors (273) and (275) slide within...http://www.google.com/patents/US5943027?utm_source=gb-gplus-sharePatent US5943027 - Telescopic antenna assembly
