Cable assemblies and connectors
GLRG179 can be terminated with BNC, F and other 75 Ω connectors for custom cable assemblies. Send us your connector pair, length and frequency band and we will build the assembly to spec.
How to choose
Match the cable to your loss budget, frequency, power and environment. For higher temperature or tighter RF stability, compare a PTFE/FEP type; for longer or higher-power runs, step up to a lower-loss family.
