More details

You get all the best features of the MFJ-941E Cross-Needle Antenna Tuner and the MFJ-931 Artificial Ground in a single compact cabinet for less cost.

Even if you have a good ground, a long connection wire can ruin its effectiveness by isolating a true RF ground from your rig, you might have these following problems caused by poor RF grounding, especially if your rig is on a second floor with no ground at all:

  • RF "hot spots" that "bite" you when you transmit
  • RF feedback that causes your rig to quit working on some bands
  • TVI/RFI that makes your neighbors hard to live with
  • Weak signal reports because of extreme ground losses or radiation pattern distortion

The MFJ-934 is unique because it has a built-in artificial ground. A ground matching knob lets you switch in inductance to bring an attached wire to a low impedance current point to form an artificial ground. A push button lets you use the cross-Needle Meter to monitor for maximum ground current.

With an artificial ground to work against, youll be surprised to see how well a random wire can work. Don't be surprised if you can work the world without hours of calling CQ. When you don't need the artificial ground feature, you can use the MFJ-934 as a full featured tuner.
