Model QD-4A accepts a standard PL-259 terminated coax connector. The design of the lower section has been recognized as the industry standard because of its strength and unsurpassed tolerances. That, coupled with the unique and heavy framed body of the quick disconnect, puts this product in a class of its own.

     All of the machined  are made with half-hard brass and finished with bright nickel-chrome. Insulators are made from rugged nylon and the hardware (bolts, washers) as well as the tension spring are fabricated with stainless steel.

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 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."
