MFJ VERSA TUNER II The MFJ-941E is designed to match virtually any transmitter to any antenna, including dipoles, inverted-vees, verticals, mobile whips, beams, random wires, and others fed by coax lines, balanced lines or a single wire. An eight-position antenna-selector switch provides versatile antenna selection. The MFJ-941E will handle up to 300 Watts of transmitter RF output power. The MFJ-941E employs a cross-needle meter so forward power, reflected power and SWR may be read simultaneously. The meter lamp can be powered by a 12 Vdc source, such as the optional MFJ-1312B power supply. Use a 2.1mm coaxial plug with the center conductor of the plug connected to the positive and the sleeve connected to ground. The ANTENNA SELECTOR switch utilizes eight positions. They are DUMMY LOAD, BALANCE, LINE, COAX 1, and COAX 2 positions for both BYPASS (direct) and TUNED (through) the tuner operation. An external 50 Ohm dummy load can be connected to the EXT LOAD connector located at the rear of the tuner.
