The General Radio GR900 series of 50-ohm precision adaptors allows users to convert from the precision sexless GR900 (14-mm) connector to other popular coaxial series (including BNC, C, N, TNC, SMA, SC, APC-7, Precifix AA/R&S 7-mm, and GR874) while retaining high-precision performance. These adaptors offer exceptionally low VSWR and exist in both plug and jack variants for most standard connector types.
