The Palstar AT-2K tuner is a manual antenna tuner for shortwave and 6m. By using the three controls (2x variable capacitor, 1x roller inductor) you get very accurate and precisely reproducible tuning results. Varicaps are tuned via a 6:1 reduction, the smooth-running roller inductor via a big crank. These components have, accordingly to its maximum allowable transmitting power of 2000W PEP, a very high voltage resistance. Impedance ranges from 20 to 1500 Ω for frequencies from 1.8 to 30 MHz, on 6m impedance is a little less.
Connect with the mode switch two different antennas either directly or via tuner to the transceiver. An additional output to connect balanced antennas is available, an optional 4:1 current balun is recommended (not included). The built-in dual cross-needle meter shows forward and reverse power as well as the resulting SWR. Switch max. measuring range of the meter from 300 to 3000W. A 'Peak and Hold' function makes it easier to read the meter. Power supply requires 12V, max. 200mA.
