SOLD! USED MFJ-931 - 1.8-30 MHz HF Artificial Ground

used artificial ground, very nice condition, 3 months warranty (No box but will be packed well)

Create an artificial ground with the MFJ-931! It 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!

It electrically places far away RF ground at your rig. Hows your RF ground? Do you have RF feedback that causes your rig to quit working on some bands? Do you get weak signal reports because of extreme ground losses or radiation pattern distortion? These problems could be caused by poor RF grounding, especially if your rig is on a second floor with no ground at all. A long connection wire can ruin its effectiveness by isolating a true RF ground from your rig. It creates an artificial RF ground! 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, It 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. It 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.
