MFJ-931 HF Artificial Ground Units make resonant a random length of wire thrown along the floor and produce 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. MFJ-931s electrically place a faraway RF ground directly at your rig, no matter how far away it is. They reduce the electrical length of the ground connection wire to virtually zero by tuning out its reactance.

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

FEATURES & BENEFITS

  • MFJ-931 artificial grounds connect between your rig and a random length of wire or a connecting ground wire
  • Tuned for maximum ground current using the built-in RF ammeter
  • Cover 1.8-30 MHz
  • Size: 7.5" x 7" x 3.5" (W x D x H).
