A dual band radio telephone with separate dual band, dual feed point transmit and receive antennas. The dual band radio telephone has two transceivers. Two feed points of the dual band, dual feed point receive antenna are coupled to respective receive branches of the two transceivers. Two feed points of the dual band, dual feed point transmit antenna are coupled to respective transmit branches of the two transceivers. Additionally, image reject band pass filters are coupled between the feed points of the dual band, dual feed point receive antenna and the respective receive branches. When the dual band, dual feed point transmit and receive antennas are spaced apart closely, the transmit branches comprise transmit filters coupled between transmit power amplifiers and the two feed points of the dual band transmit antenna.
