The AS-603A is an automatic antenna switch for three radios and six antennas. It has internally two independent switches. One to select the radios and another to select the antennas. The operation is individual, which means that only the selected radio will have access to the antennas. Unused antennas are automatically grounded.
To facilitate the operation, the AS-603A also has a third internal switch that switches the Send commands and the Com port to the selected Radio.

The AS-603A supports communication with the following radios:
Icom (CI-V), Kenwood (RS-232), Elecraft K3 (RS-232), Yaesu (RS-232) or any other Radio that uses one of these communication protocols.
