The MFJ-949E is a 300 watt RF output power antenna tuner that will match any transmitter or transceiver to virtually any antenna. Peak or average forward and reflected power and SWR can be read on the illuminated cross-needle meter.

The wattmeter has an internal lamp that backlights the meter scale. The lamp circuit requires power from an external 12 Vdc source, such as the optional MFJ-1312D power supply. The rear panel jack accepts a 2.5 mm coaxial plug with a positive center pin polarity.
 
The MFJ-949E uses a "T" matching network and covers all bands between 160 and 10 meters. This network will tune dipoles, inverted-vees, verticals, mobile whips, beams, random wires, and many other antennas. The MFJ-949E 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.
 
An internal eight position antenna-selector switch selects a built-in 50 ohm dummy load, two separate coaxial line outputs, or a single wire line-balanced line output. All of these functions can be selected in tuned (with tuner's "T" network in line) or bypassed (no tuning circuit) configurations.
