Our take on the Universal CB Antenna Mount SO-239 Stub, Stainless Steel Antenna Pole Mast Mount L-Bracket with U-Bolts and Install Screws 3/8-24 UNF

This is a stainless steel L-bracket with an SO-239 female socket and a 3/8-24 threaded stud, made to bolt a CB or ham antenna to a pole, mast or flat surface. The 10mm hole and included U-bolts let it clamp to round masts or bolt through a wall or rack. It is a plain mechanical part: no cable, no connector on the antenna side beyond the stud, and no ground lead. Buyers who want a cheap, simple pole mount with a standard PL-259 socket will find it fits most CB whips and many VHF/UHF antennas; buyers expecting a weather-sealed, pre-wired mount should look at a mirror or lip mount instead.

Pros
  • Standard SO-239 socket takes a PL-259 coax plug
  • 3/8-24 stud fits most CB and ham antenna bases
  • Stainless steel resists rust better than painted steel
  • U-bolts and screws included, so no extra hardware run
  • L-shape gives a 90-degree mount on flat or round surfaces
Cons
  • No coax cable or ground strap included
  • No gasket or weather seal around the socket
  • Thin bracket can flex with a long, heavy whip
  • U-bolts suit only a narrow range of mast diameters
  • Stainless threads can gall without anti-seize

Questions and answers

Will this fit a standard CB antenna?
Yes, if the antenna has a 3/8-24 threaded base. The SO-239 socket accepts a PL-259 coax connector, the common CB standard.
Does it come with coax cable?
No. It is the bracket and socket only. You supply the coax and a PL-259 plug.
What size mast does the U-bolt fit?
The U-bolts are sized for small round masts and poles, roughly 1 to 1.5 inches. Measure your mast before ordering; larger poles need longer U-bolts.
Can I mount it on a wall or roof?
Yes. The 10mm holes in the L-bracket let you bolt it to a flat surface, and the bracket can also clamp to a pole with the U-bolts.
Is it weatherproof?
The stainless steel resists rust, but the socket has no gasket. Seal the coax connection with tape or self-amalgamating tape to keep water out.
Do I need to ground it?
The bracket does not provide a ground path by itself. Bond the mast or bracket to earth for a proper station ground.
