The Comet CAT-300 is a high-performance manual antenna tuner covering 1.8–50 MHz for HF and 6-meter operation, enabling precise impedance matching between your transceiver and antenna system for maximum power transfer.
Built with a wide 300-watt PEP power rating, this tuner easily handles most base and mobile amateur radio setups, improving signal quality and reducing reflected power for clearer communication and longer equipment life.
Features an integrated cross-needle meter that simultaneously displays forward and reflected power along with SWR, allowing fast visual tuning and real-time transmission monitoring without external instruments.
Offers broad matching range of 3–300 ohms, ensuring compatibility with dipoles, verticals, long-wires, and beam antennas; includes high-quality variable capacitors and inductor coil for reliable manual tuning precision.
Designed with durable metal chassis construction and intuitive front-panel controls, the CAT-300 is compact enough for portable field use yet robust for permanent base-station installations, ideal for amateur operators who demand performance and longevity.
