No need to call for a radio check when you have this compact, easy to use, unit on-board. The ART-3 tests receiver function as well as output power and VSWR (antenna efficiency).It is powered by an internal battery or can be connected to ships 12 VDC with the supplied power cable. Battery level can be checked at the flip of a 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, the AS-2 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.
Used to connect the ART-3 in line with your antenna, or for the CS2 switch. Includes 2 PL259 connectors, installed. Packed in a plastic bag with header card.
