Note
The MFJ-934 is a 300 watt (175 watts on 160 meters) RF output power antenna tuner and artificial ground system that will match any transmitter or transceiver to virtually any antenna.
A special circuit in this tuner cancels the reactance of a ground lead or counterpoise, and reduces problems caused by RF "in the shack". Forward power, reflected power, ground current, and SWR can be read on the wattmeter's illuminated cross-needle meter.
The MFJ-934 tuner section uses a "T" network and covers all bands between 160 and 10 meters. This network will work with dipoles, inverted-vees, verticals, mobile whips, beams, random wires, and many other antennas. The MFJ-934 has rear panel connectors for coaxial, single wire or two wire feedlines. A built-in 4:1 balun allows the use of balanced open wire, twinlead, or twin-axial feedlines.
