A radio radio quasi-circulator-jammer system, which connects a transceiver and a jammer unit to a single antenna, for isolating the transceiver from the co-located transmitter jammer. The radio quasi-circulator-jammer system includes includes a quasi-circulator having a transformer, a matched electrical load having an electrical impedance substantially matched to the antenna electrical impedance and three radio signal splitters adapted to split incoming radio power signals into two substantially equal outgoing radio power signals. The three radio signal splitters and said transformer are arranged produce: a circulation within the quasi-circulator of about one-half of output power of the jammer transmitter and the communication transmitter in a first direction and a circulation of about one-half of said output power of the jammer transmitter and the communication transmitter in a second direction opposite said first direction and a circulation within said quasi-circulator of about one-half of input power received by said antenna in said first direction and a circulation of one-half of said input power received by said antenna said second direction; with the transformer positioned within said quasi-circulator so that substantially all output power of the two transmitters that is not otherwise transmitted or dissipated is cancelled in said transformer.
