Firestik - K1A - Internal Locking Quick Disconnect
There are times when it is convenient to be able to quickly remove your antenna without fumbling around for tools. Perhaps your antenna is too tall to fit into your garage, or you often park in a high theft area. Maybe you don't use your antenna every day but want to be able to snap it on in a hurry when you do want to use it. If that's the case, a quick disconnect is all that you need. Compatible with 3/8"-24 threaded antennas and accessories.

The K-1A model has an internal locking mechanism. This design requires more handling and machining than an external locking design, but offers weather protected components and additional security from casual thieves who may not be familiar with the push-n-twist locking mechanism. The K-1A can be used with any of our antennas up to 5ft (1.5m) long and with all accessories too. The actual installed size is 2.9" (74mm) high x 0.600" (15mm) diameter. The upper and lower body parts are made of chrome plated machine brass. The locking pin and the spring are made from stainless steel.
