INSTAllATION
Connect the RF output of the transmitter to the RF IN
connector on the rear of the Al-80A with 50 ohm coax. Con-
nect the existing station antenna system to the RF OUT con-
nector on the Al-80A with RG-8 type coax. Connect the
RELAY phono jack on the rear of the Al-80A to the normal-
ly open terminals of the RELAY jack on the transmitter. The
RELAYjack on the Al-80A has positive 12 VDC open circuit
and provides 100 MA of current when pulled to ground. Con-
nect as short a ground lead as possible from a good earth
ground to the GND terminal.
The 12V connection on the rear panel provides 12 VDC at
100 MA maximum to operate external dial lamps or
accessories.
