Operating Your AT5K
1-800-773- 7931 W W W .PALST AR.CO M
Before Operating
1. To avoid possible damage to the
AT5K set INPUT, OUTPUT, INDUC-
TOR, and POWER RANGE switches
as outlined in the chart before applying
transmitter power.
2. Begin tuning with your transmitter/
lamp into the tuner set at a low output
power setting (50-150 Watts).
Tuning
1. Select the band and frequency of
desired operation.
2. Set TUNE and INDUCTOR controls
to the suggested setting before apply-
ing transmitter power (see chart).
Actual settings will vary from antenna
to antenna.
3. Set your transmitter/amplifier to a
low power output (100-150 watts). If
your transmitter/amplifier combination
has a LOW POWER position, select
that position to obtain the 100-150
watts for the initial tune-up.
4. Preset the INPUT, OUTPUT, and
INDUCTOR values shown in the chart
supplied for each band or on the label
on the front panel. Select the type of
antenna feed you require (BALANCED
or COAX) with the pushbutton on the
front panel. Note: BALANCED shows
red LED.
5. Set the POWER RANGE switch to
300 W (with POWER range switch
meter button out).
6. Set the OUTPUT SELECTOR switch to
the position matching your antenna connec-
tion. To tune your antenna, the switch
selection
must be set to: COAX 1 TUNED,
COAX 2 TUNED or WIRE
(BALANCED ANTENNA). Selecting
COAX 1 DIRECT, COAX 2 DIRECT or
BYPASS bypasses the tuning selection.
WARNING: DO NOT OPERATE THE AT5K
WITH THE COVER OFF.
