K-332 Cable Assemblies Now - MAXRAD/PCTEL K332-406-1000 MHz Ground Plane Disc for Fiberglass Vehicles

For GMRS it brought my SWR down from 1.4 to 1.04.

I have a few trucks. One is a fiberglass body and this plate did the trick in creating a proper ground plane. Now my mobile CB reaches out on the road.

Used this with a mobile antenna on my Maverick X3.

Not worth it. Waste of money.

The media could not be loaded.  I drilled the center hole and installed this under my fiberglass top for a UHF ground plane. It works great and improved my antenna performance greatly.
