CC-SAFR is designed to fit RG174, RG178, RG188, RG196 and RG316 cable, and cables of similar outer diameter and core wire size.

This connector has a characteristic impedance of 50 ohms, and needs to be mated with 50 ohm coaxial cable in order to prevent signal loss, noise, and/or transmitter damage due to signal reflections at the point of mismatch. 50 ohm cable, connectors, and adapters are commonly used in wifi (802.11 wireless LAN) antennas, ham tranceivers, and other radio frequency (RF) analog and digital signaling, microwave, radar, hi-fidelity professional audio, non-destructive testing (NDT), oil and petroleum production, ultrasonic transducers, accelerometers, strain gauges, and some professional video applications.
