Here is a used, good condition, NMO trunk-lip antenna mount. This appears to be an OPEK mount, since the soldered-on PL-259 connector that terminates the 15-foot RG-58U feed line is engraved with that company's name. As seen in the photo, the rubber washer surrounding the mount shows some cracking, but is still water-tight. The hex-wrench required for installation is included, along with a plastic screw-on rain cap. Tested/good with proper continuity between the center-pins of the mount and PL-259, and the "ground" side of the mount and the PL-269 shell ... and NO continuity between the PL-259 center-pin and shell.
