• a plurality of peripheral antennas positioned symmetrically around the central antenna;
• a first coupler providing a first radio connection and a second radio connection;
• a first 180 degree hybrid coupler coupled to a first two diametrically opposed antennas of the plurality of peripheral antennas;
• a second 180 degree hybrid coupler coupled to a second two diametrically opposed antennas of the plurality of peripheral antennas;
• a third 180 degree hybrid coupler coupled to the first and second 180 degree hybrid couplers, the third 180 degree hybrid coupler providing a third radio connection and a fourth radio connection;
• a wireless broadband circuit having a transmit node coupled to the first radio connection, a receive node coupled to the second radio connection, and a secondary receive node coupled to the third radio connection;
• a Land-Mobile-Radio circuit;
• a controller;
• a single-pole-double-throw relay having a pole, a first throw, and a second throw, the pole coupled to the Land-Mobile-Radio circuit, the first throw coupled to the fourth radio connection and the second throw coupled to the central antenna;
• wherein the first, second, third, and fourth radio connections are decoupled from each other, and the first, second, and third system radio connections are decoupled from the central antenna.
