6.0 INSTALLATION (Refer to fig. 7, page 11)
6.1 Connect a 50 ohm coax cable 60-72" long (supplied) from the transceiver RF output to
the ALPHA 89's RF INPUT jack.
6.2 Connect a transceiver T/R control line which is shorted on transmit and open on receive to
the 89's RELAY jack, using a standard "RCA" ("phono") plug. Cable should be shielded type.
6.3 Connect a nominally 50 ohm antenna for the frequency to be used to the 89's RF OUTPUT jack.
6.4 If desired, connect a cable from the the ALC jack to the transceiver ALC input, using an RCA
plug. See sect. 8.3.
6.5 Connect a heavy copper strap or braid from the ground stud & wing nut on the rear panel of the
ALPHA 89 to the chassis of the transceiver and other station equipment, and to the main station RF
ground.
