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.
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.
