AT2K SPECIFICATIONS

PALSTAR
Building on success, Palstar upgraded the best-selling AT1500CV
throughout to create the American-made Palstar AT2K Antenna Tuner.
The AT2K optimizes the performance of your antenna and transmitter
by providing adjustable impedance matching using a T-type circuit
configuration.
The AT2K also measures the power (upgraded to include a PEAK/PEAK
HOLD function) and Voltage Standing Wave Ratio (VSWR or SWR),
which allows you to tune the SWR to the lowest possible for the
selected transmission frequency.
The AT2K also features a precision steatite ceramic core roller inductor
with a plated roller wheel and roller shaft. The smaller size permits
operation on 6 meters.
A high voltage ceramic wafer switch allows selection between coax
feedlines or wire-fed antennas. DIRECT switch positions bypass the
impedance matching circuit but allow for the SWR, FORWARD, and
REFLECTED and PEAK power meter FUNCTIONS.
Tuning is achieved with the front panel mounted controls. The 6:1 ratio
Vernier dials allow for tuning with precision and accuracy, while the
Inductor crank handle facilitates coarse adjustments. The range of the
meter (300W/3000W) is selcted by a push button switch located on the
front panel.
