Firestik stud mounts have become the standard of our industry. This wasn’t by accident. It was because users learned to appreciate their outstanding design and material quality. Instead of inexpensive aluminum, they use 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 cadmium plated hardware, they use stainless steel. Furthermore, their heavy-duty 3/8″ center shanks can mean the difference between trouble free use and lost antennas. Also may be used with any 3/8″-24 threaded accessories.
The K-4 stud utilizes ring terminal connectors (supplied) making it compatible with non-PL-259 terminated coaxial cables. In a typical installation, antennas with 0.600″ (15mm) of exposed threads can be used without the fear of bottoming out before proper tightening is accomplished. The K-4 can be used in any mount or mounting surface with a 1/2″ (13mm) hole.
