Rf coaxial cable

RF cable, which was made by super soft braided shielding wire and precision connectors. It has superior product performance, like wide bandwith, low insertion loss, low VSWR, bend resistance and reliable connection. And it was widely used on mircrowave communications, microwave measurements and other fields.
