Abstract

A UHF range antenna comprises a planar surface (2) connected to the inner conductor of a coaxial antenna feed cable and a grounded part (3) connected to its outer screen. Two trap devices (7, 8), one adjacent the antenna and the other a specific distance along the feeder towards a receiver (6) isolate the coaxial cable screen so that it acts as an antenna in the VHF range. The received VHF signals are coupled to the inner conductor of the cable at the receiver end.
