Dual receiver/transmitter radio devices with choke

A radio device for transmission of wireless signals, the device comprising:

• a first parabolic reflector;
• a second parabolic reflector;
• a radio circuitry configured for transmission of radio-frequency signals from the first parabolic reflector and configured for reception of radio-frequency signals from the second parabolic reflector;
• and
• an isolation choke boundary coupled between the first parabolic reflector and the second parabolic reflector, the isolation choke boundary comprising a plurality of ridges extending between the first and second parabolic reflectors, wherein the isolation choke boundary provides greater than 10 dB isolation between the first and the second parabolic reflectors.

A radio device for transmission of wireless signals, the device comprising:

• a first parabolic reflector comprising a transmitting reflector;
• a second parabolic reflector comprising a receiving reflector;
• a radio circuitry configured to transmit radio-frequency signals from the parabolic transmitting reflector and to receive radio-frequency signals from the parabolic receiving reflector;
• and
• an isolation choke boundary between the parabolic transmitting reflector and the parabolic receiving reflector, wherein the isolation choke boundary comprises at least 10 ridges extending between the parabolic transmitting reflector and the parabolic receiving reflector, the ridges extending in the direction of an outer edge of the transmitting reflector or and outer edge of the receiving reflector.
