Abstract
An antenna coupling network for supplying VHF television carriers to a VHF tuner of a television receiver and weather band carriers to a tuner of a weatherband radio incorporated in the television receiver from a single monopole antenna without adverse interaction simply comprises a first wire connected between the monopole antenna and the VHF tuner and a second wire wrapped around the first wire a predetermined number of times and connected at one end to tuner of the weatherband radio. The number of turns are selected to form a series resonance at a midpoint of the weather band. Desirably the other end of the second wire is left unconnected.
