QRP Loop Antenna Tuner MFJ Excellent Quality

MFJ, QRP Loop Tuner, M, Rig Mount

The MFJ Mini Loop Tuner TM is a small, versatile, highefficiency device that turns a wire loop into a highefficiency multiband transmitting antenna system.

Designed to mount directly to your radio, it is perfect for onthego operation. It is designed for ohm use at QRPpower input on all modes.

The MFJ Mini Loop Tuner TM resonates various lengths of wire to create a HiQ tunedcircuit that functions as a transmitting loop. It uses special lowloss capacitors for high efficiency and interfaces the HiQ transmitting loop circuit with any length of Ohm coaxial cable.

No ground, radials, or counterpoise system are needed. The MFJ Mini Loop Tuner functions with wire loops of any shape circle, square, rectangle etc. For highest efficiency, use wires approaching one quarter wavelength erected in the shape of a circle.

The MFJ Mini Loop Tuner TM uses fixed wire lengths to cover roughly a 1.5:1 frequency ratio ( MHz, MHz, etc.). Exact frequency coverage depends on each individual installation and involves your choice of wire length, loop diameter, loop shape, height above ground level, plus other stray factors in the immediate operating environment.
