Note
The Palstar AT1500CV is an American-made antenna tuner designed to provide adjustable impedance matching for amateur radio operations. It uses a T-type circuit configuration to optimize the performance of antennas and transmitters.
Features
– It is rated for 1500 Watts PEP for SSB and 1200 Watts average for single-tone continuous operation.
– Frequency Coverage: The tuner operates across the HF spectrum from 1.8 MHz to 30 MHz.
– Impedance Range: It can match antenna impedances ranging from 20 Ω to 1500 Ω.
– Roller Inductor: Features a precision 26 µH steatite ceramic core roller inductor with a silver-plated roller and shaft.
– Capacitors: Utilizes two independently variable 315 pF capacitors rated at 4.5 kV.
– Tuning Controls: Tuning is achieved through 6:1 vernier drives for input and antenna tuning, alongside a crank handle for coarse inductor adjustments.
– Metering: It includes a dual-movement cross-needle meter that simultaneously displays forward and reflected power. It has two selectable ranges: 300W and 3000W.
