Automatic Coaxial SwitchPart #: AS-2This innovative switch toggles two radios to one antenna. It mounts out of the way, because you don't have to get at it to use it. When you key the microphone on one of the radios, it switches the antenna to it. Automatically. The radio stays locked onto the antenna until the automatic switch detects a transmit signal from the other radio.
