Cable assemblies and connectors

GLRG58 can be terminated with SMA, N, TNC, BNC and FME 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. Browse the full range on our products page or request a quote for a made-to-order assembly.
