What is RG225 Coax Cable?

RG225 coax is a 50 ohm, flexible, radio frequency coaxial cable used in direct burial applications. The cable’s construction starts with an inner conductor insulated with a cable core and topped with an outer conductor that has both an inner and outer braid. This coax cable is then topped with a vapor barrier and fiberglass braid jacket. In addition, the RG225 cable is rated to MIL-DTL-17 specifications.
