Work in the RF or audio/video market long enough, and you'll find a time when you need an adapter that you just don't have on hand. This RF Adapter Kit is the problem solver you need! Using included connectors and universal couplers allows you to easily make 64 inter-series or intra-series connector combinations by simply screwing two connectors together. Every technician should keep this kit in his toolbox, service vehicle or tool cart. Make the adapter quickly in the field (with no soldering or crimping required) to get the equipment up and running, then replace the adapter later when you have more time. Each adapter has a gold-plated brass body with center conductors, and a Teflon(R) insulator material.
