Mfj-1644 150 watt 80 - 10 meter whip tuner, artificial ground


The Whip Tuner/Artificial Ground is a versatile antenna solution for portable, fixed station, and emergency use. It operates on a wide frequency range of 3.5-30 MHz, with an effective 150-watt power output. The setup is simple, requiring only a short whip and counterpoise wire. The high power, hi-Q 3-core variable loading coil efficiently resonates with the whip or random wire, while the identical inductor tunes the counterpoise. 

For operation on 30-10 Meters, the Whip Tuner/Artificial Ground includes a 4 1/2 foot telescoping whip antenna and counterpoise assembly. To enhance efficiency on 80-30M, you can add a longer whip or random wire and an external loading coil. The built-in reversible L-network allows for tuning to low SWR, while the current balun decouples the radiating elements. By tuning for maximum current on the RF Current Meter, you can achieve maximum radiated power and minimum SWR. 

The Whip Tuner/Artificial Ground also features a sensitivity control that enables the use of QRP to 150W QRO. Its ultra-low capacitance fiberglass antenna/counterpoise insulator minimizes shunting antenna current to ground, resulting in maximum radiated power. With a compact size of 7 1/4W x 2 1/4H X 2 1/2D inches, it is a convenient and effective antenna solution.
