Operating Your AT1KP
1-800-773- 7931 W W W .PALST AR.CO M
Before Operating
1. To avoid possible damage to the
AT1KP set the POWER RANGE
switch to the OUT position (Low
range) and set the TUNE and INDUC-
TOR as outlined in the chart before
applying transmitter power.
2. Begin tuning with your transmitter/
amp into the tuner set at a low output
power setting (50-100 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/amp to a low
power output. If your transmitter has a
TUNE position, select that position.
4. If you use a linear amplifier, set it to
Standby. Do not use the linear ampli-
fier until the AT1KP is tuned.
Do not
exceed 800 watts average (single
tone) during tune-up
.
5. Set RANGE switch to 300 W
(button out).
6. Set the DIRECT/TUNED mode
switch to BYPASS or the position
matching your antenna connection. To
tune your antenna, the switch selection
must be set to: COAX 1 TUNED,
COAX 2 TUNED or WIRE
(BALANCED ANTENNA).
WARNING: DO NOT OPERATE THE AT1KP
WITH THE COVER OFF.

The Palstar AT1KP Antenna
Tuner is an American made im-
pedance matching network that
can provide balanced and un-
balanced output.
The AT1KP optimizes the per-
formance of your antenna and
transmitter or SWL receiver by
providing adjustable impedance
matching using a T-type circuit
configuration with a dual-stator
differential variable capacitor.
The AT1KP also measures the
power and Voltage Standing
Wave Ratio (VSWR or SWR)
which allows you to tune the
SWR to the lowest ratio possible
for the selected transmission
frequency.
The AT1KP features a precision
roller inductor with a steatite
ceramic core. The innovative
differential capacitor design sim-
plifies operation by reducing the
number of knobs and eliminat-
ing false peaks while tuning. It
also results in a more compact
case that takes up less room on
the operating desk.
The AT1KP is designed to han-
dle both Balanced line feeds
and Coax feeds with a front
panel mounted switch to select
between feeds.
Tuning is achieved with the front
panel mounted controls. The
Vernier dial allows for fine tun-
ing with precision and accuracy,
while the Inductor crank handle
facilitates coarse adjustments.
