Quick Overview

This Firestik stud mount is our best-selling stud and the one we recommend for general CB applications! Instead of low-cost components, Firestik uses stainless steel, machined brass and oversized hex stock for a high-quality stud that will last. The SO-239 connection is compatible with all PL-259 style coax connections. For best performance, we recommend using with antennas 5' and shorter. If you'll be using a longer antenna, you'll want to consider a ball mount or an oversized, heavy-duty stud.

Details

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-4A 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-4A offers. The K-4A should be used whenever a PL-259 terminated coax cable is to be used (K-8A, K-9A, R-8A, R-9A). Like the K-4, 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.

My father was desperately seeking for this part. After numerous searches online, we came across this site. It has great prices and carries "hard to find" items plus fast shipping! We will definitely buy again and will spread the word! (Posted on April 3, 2013)

This stud mount is used with the bandi mount for my '07 FJ Cruiser along with a medium spring and quick disconnect which are hooked up to a 3' Firefly antenna. I have had no problems with reception or transmitting. In the end I really like this stud and would definitely recommend it. (Posted on February 7, 2013)

I picked this up for a CB whip I modified for the 10 meter ham band. I have the antenna mounted outside. So far this stud works fine. Great service by the way! I will be back if I need any more CB items for my ham radio projects. (Posted on February 5, 2013)
