Our take on the ProComm JBC986 3" Heavy Duty Ball Mount

The ProComm JBC986 is a chrome-plated CB antenna ball mount with a swiveling ball that lets you bolt it to a vertical, horizontal or angled surface and still stand the antenna upright. It uses a heavy-duty SO239 stud with 3/8x24 threads, so it takes any antenna with a 3/8-inch bolt, and it ships with a chrome barrel spring. Two lug-style coax connections ride on the mounting screws, which simplifies wiring compared with mounts that need a separate stud and cable. It is built for full-length 102-inch whips, so it suits drivers and hobbyists who want a sturdy, adjustable base rather than a fixed L-bracket.
