FireStik® K-4AX - CB Mount for K-4A Stud Antenna

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" (13 mm) holes. In a typical installation, antennas with 0.680" (15 mm) of exposed threads can be used without the fear of bottoming out before proper tightening is accomplished.
Firestik stud mounts have become the standard of industry. This wasn't by accident. It was because users learned to appreciate their outstanding design and material quality. Instead of inexpensive aluminum, chrome plated machine brass is useed. Instead of 9/16" (14 mm) hex-stock - 5/8" (16 mm) stock. Instead of ABS or inferior plastic insulators - nylon. Instead of cadium plated hardware - stainless steel. Furthermore, heavy-duty 3/8" center shanks can mean the difference between trouble free use and lost antennas. Some businesses in the industry have copied the look of the Firestik antenna studs but those "low-cost targeted" parts have a tendancy of coming apart. It is buyer beware! You might save a dollar when you buy them and you might loose a $25+ antenna as your reward.
