Our take on the 3/8" x 24 Stud CB Antenna Mount to SO-239 Adapter fit 1/2" Hole by Heavy Chrome-Plated Brass for CB Ham Radio Antenna

This is a chrome-plated brass stud adapter that converts a 3/8-24 antenna thread to an SO-239 socket and mounts through a 1/2-inch hole. It is a small metal part, not a full mount: it lets a 3/8-24 whip or stud screw into a coax-fed SO-239 setup, or lets an SO-239 connector sit on a 1/2-inch panel hole. It suits CB and ham operators building or repairing a mobile or base antenna mount who already have the bracket, coax and connector. Rivals in this niche are plain steel or nickel adapters; brass with chrome plating resists corrosion better, but the 1/2-inch hole fit and 3/8-24 thread are the only compatibility it offers, so check both before buying.

Questions and answers

Will this fit my antenna?
Only if your antenna uses a 3/8-24 thread and your mount has a 1/2-inch hole with an SO-239 connection. Check both before buying; there is no other size option.
Is this a complete antenna mount?
No. It is an adapter stud only. You still need a bracket, coax cable and the mating PL-259 connector.
Does it improve signal?
It only makes the mechanical and electrical connection between a 3/8-24 antenna and an SO-239 feed. Signal quality depends on your antenna, mount grounding and coax, not on the adapter itself.
Is it brass or steel?
The body is brass with chrome plating, which resists corrosion better than bare steel in outdoor mobile use.
Can I use it for a base station?
Yes, if the base mount has a 1/2-inch hole and SO-239 fitting. It is not limited to mobile setups.
What is in the box?
One adapter: the 3/8-24 to SO-239 stud mount. Nothing else is included.
Where is the 3/8" x 24 Stud CB Antenna Mount to SO-239 Adapter fit 1/2" Hole by Heavy Chrome-Plated Brass for CB Ham Radio Antenna cheapest?
