Flexible semi-rigid microwave coaxial cables
PRODUCT
DESCRIPTION
astro-cobra-flex®
is high performance semi-rigid cables which utilize a seamless outer conductor
to provide excellent RF shielding. The convoluted design gives this cable
excellent phase tracking characteristics over temperature due to minimal
dielectric migration. These cables are offered with many options including
tin-plated outer conductor, copper clad steel center conductor for low thermal
conductivity in cryogenic applications.
