- MFJ-931 creates an artificial RF ground! It resonates a random length of wire thrown along the floor and produces a tuned counterpoise. This ground effectively places your rig near actual earth ground potential even if your rig is on the second floor or higher with no earth ground possible.
- Also, the MFJ-931 electrically places a far away RF ground directly at your rig -- no matter how far away it is. It reduces the electrical length of the ground connection wire to virtually zero by tuning out its reactance.
- The MFJ-931 connects between your rig and a random length of wire or a connecting ground wire. Its tuned for maximum ground current using the built-in RF ammeter. The MFJ-931 Artificial RF Ground covers 1.8 - 30 MHz and measures a compact 7.5W x 3.5H x 7D inches.
- Full 1.8-30MHz Operation Custom designed inductor switch, 1000 volt tuning capacitors, Teflon insulation washers and proper L/C ratio gives you arc-free no worries operation with up to 300 Watts 1.8 to 30 MHz
- Tunes any Antenna Tunes out SWR on dipoles, verticals, inverted vees, random wires, beams, mobile whips, shortwave receiving antennas.... Nearly anything! Use coax, random wire or balanced lines. Has heavy duty 4:1 balun
- Custom Inductor Switch The inductor switch is the most likely component to burn up in any antenna tuner. MFJs inductor switch in the MFJ-949E was custom designed to withstand the extremely high RF voltages and currents that are developed in your tuner.
- 8 Position Super Antenna Switch Lets you select two coax fed antennas, random wire/balanced line or built-in dummy load through your MFJ-949E or direct to your transceiver.
- More hams use MFJ-949s than any other antenna tuner in the world! Has MFJs full size 3 inch lighted Cross Needle Meter (not a puny "meter" you cant read). Lets you easily read SWR, true peak forward and average reflected power simultaneously on 300 Watt or 30 Watt ranges. Lamp has on/off switch, requires 12 VDC or 110 VAC with MFJ-1312D (Not included)
