MFJ-904 Compact Tuner
The MFJ-904 is a compact tuner for the shack or on the road. With two variable capacitors and a coil in T-circuit, the 904 matches almost all antennas from 80 to 10m, up to 150W transmit power.
All coaxial cable-fed antennas can be used. End-fed wires can also be used, in which case the tuner must have a good earth connection.
The tuner is equipped with a "bypass" switch, so that a well-matched antenna on some bands can be used permanently without having to remove the tuner every time. The built-in SWR meter shows forward and reverse power with a cross needle instrument, the measuring range is switchable between 0-30 and 0-300W. This makes the tuner also well suited for QRP equipment. The instrument is illuminated, for this purpose a 12V connector is available on the backside.
