The Listen Technologies LA-123 antenna is designed to mount on the
rear BNC antenna connector of 72 MHz versions of the Listen Technologies
receiver/amplifier, or LR-600
receiver/speaker. It can also be used to create a custom remote antenna,
such as a wall plate mounted antenna. The Listen Technologies LA-123 antenna
is included with the Listen Technologies LA-125 which allows the antenna
to be placed in the front of the equipment rack.
