The last thing you want to skimp on is something as crucial as your stud mount. You won’t find any cheap components here, instead Firestik used stainless-steel, machined brass and oversized hex stock for the best quality mount for general CB applications. The lug-style connection is compatible with terminal and ring-style coax. For best performance, we recommend using with antennas 5' and shorter.

Model / SKU:Firestik K4
Recommended for:
All-purpose CB use for antennas 5' and shorter. Lug-style stud is used with terminal and ring-style coax cables, which are ideal for when space is tight. For antennas longer than 5', you should use a heavy-duty stud or ball mount.
Compatible with:Accepts all fiberglass and center-load antennas with a 3/8" x 24 thread. Lug-style coax connection is compatible with terminal and ring-type coax cable connections. Designed to fit 1/2" stud holes, the industry standard on all CB mounts.
Installation Notes:It's crucial to install the nylon washer between the metal mounting surface and the top antenna nut. Otherwise, a short will occur. See stud washer troubleshooting for more information. If installing on a flat surface without a mount, a 1/2" hole should be drilled.

The importance of the stud mount cannot be overstated! The antenna stud mount acts as a bridge between the antenna and the coaxial feed line. Accordingly, it needs to allow for efficient transfer of your signals to and from the transceiver. If the stud mount doesn't perform that task efficiently, you end up with unneeded loss. And if that isn't enough, the stud mount must be strong enough to withstand the stress from an antenna subject to severe wind load and vibration.

Firestik stud mounts have become the industry standard. This wasn't by accident; it's because users learned to appreciate their outstanding design and quality material. Instead of inexpensive aluminum, Firestik uses chrome-plated machine brass. Instead of 9/16" (14mm) hex stock, they use 5/8" (16mm) stock. Instead of ABS or inferior plastic insulators, they use nylon. Instead of cadium-plated hardware, they use stainless steel. And their heavy-duty 3/8" center shanks can mean the difference between trouble-free use and lost antennas. Some businesses have copied the look of the Firestik antenna studs, but those "low-cost targeted" parts have a tendency to come apart -- it's buyer beware! You might save a dollar, but you could also lose a $25+ antenna as your "reward."

This K-4 stud mount has been praised by communications professionals for 20 years. You can actually pay more for a stud mount but you certainly will not get more than what the K-4 offers. This stud is designed for 1/2" (13mm) holes. In a typical installation, antennas with 0.680" (15mm) of exposed threads can be used without the fear of bottoming out before proper tightening is accomplished.
