Firestik K-4A Heavy-Duty SO-239 Stud Mount w/Hardware

The importance of the stud mount cannot be over stressed! The antenna stud mount acts as a bridge between the antenna and the coaxial feedline. Accordingly, it needs to allow for efficient transfer of your transmitted and received 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 all of the stress placed upon it from an antenna that is subject to severe wind load and vibration.


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, we use chrome plated machine brass. Instead of 9/16" (14mm) hex-stock, we use 5/8" (16mm) stock. Instead of ABS or inferior plastic insulators, we use nylon. Instead of cadium plated hardware, we use stainless steel. Furthermore, our 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.


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.
