5. Connect the IN connector to your transceiver. Do not install any active antenna
matching devices on this port. In general, the shortest and most direct cable
connection is best, although high quality cables can be very long without adverse
effect on performance. RG-58/U or Mini-8 (RG-8X) style cables are acceptable.
You should never use a tuner of any type on the amplifier input, nor should
you drive this amplifier with over 100 watts peak envelope power.
6. The ALC line is optional. In general, transceiver internal ALC is all that is
necessary. The ALC monitors the RF output power and reflected power supplied
by the ALS-706 to the load.
7. Operate the bandswitch manually during initial testing. Do not connect band
decoders, band data lines, or computer interfaces until initial tests are completed
and the amplifier is functioning normally.
8. When using an automatic antenna tuner that has the capability to inhibit the
amplifier from operating either during tuning or when conditions are outside of the
tuner’s capability; and when the Radio Interface Cable that has the Amplifier
Relay line included (not using the RELAY jack); the KEY LINE can be used. The
KEY LOOP Switch is used to route the key signal from the interface to the amp
directly or out the KEY LOOP jack.
a. If the KEY LOOP is not used, set the KEY LOOP Switch to OFF so the
Radio Interface Cable can key the amplifier.
b. If the KEY LOOP is used with an automatic antenna tuner switch the KEY
LOOP Switch to ON, run a cable from the KEY LOOP connector on the
amp to the AMP ENABLE IN connector on the tuner, and run a cable from
the AMP ENABLE OUT connector to the RELAY connector on the amp.
