Screw this onto a SO259 antenna base, then screw the PL259 antenna onto this adapter. Select either VHF or UHF operation by attaching the longer or shorter counterpoise whips (respectively) into the threaded holes in the adapter. As the instructions mention, be gentle - the threads are small and soft. Make certain the whips are inserted straight and not cross-threaded, then carefully screw them in with fingertip pressure only. DO NOT FORCE and use no tools. Given that these are for stationary base use, they don't need to be very tight, simply secure enough to make reasonable electrical contact. For mobile use, for example on a motorcycle or plastic top with insufficient metal to provide a suitable ground plane, I would recommend using adhesive or cement after attaching the counterpoise whips to ensure they don't back out with vibration. It should be something removable, however - changing between VHF and UHF frequency ranges requires removing one set of whips and installing the other.Once installed, this does a good job of improving the ground plane of an antenna that does not include one as part of the basic design. That is typical of mobile antennas designed to be installed on a metal vehicle which use the metal surfaces at the ground plane. It's also easy to set up and take down for portable operation, setting up a temporary base operation in support of community service or an emergency. Disassemble, put the parts in a zipper bag, and keep it with the stand used to hold the antenna. You will be ready to support a temporary base operation at a moment's notice.

While installing one of the ground plane rods broke off with very little effort... It came with three shorter rods but the threaded part is broke off in the hole so I can't use the shorter ground plane...

Made a mag mount ground plane for VHF/UHF Amateur Radio use. Works great, highly recommended.
