PALSTAR

The Palstar AT5K-HP Antenna Tuner is an American-made impedance
matching network that can provide unbalanced and balanced ouput
with a power rating of 3500 watts (single tone carrier) and 5000 watts
PEP at certain Z ranges.

Tuning is achieved with the front panel mounted controls. The Vernier
capacitor dials allow for tuning withprecision and accuracy, while the
inductor crank handle facilitates coarse adjustments.
