A coaxial cable connector interface for allowing signals to be transmitted over a coaxial transmission line between devices includes a coaxial cable and a cable connector that allows the coaxial cable to be attached to the devices. The coaxial cable includes a solid outer conductor that has corrugations to increase flexibility of the coaxial cable. The cable connector has a crimp portion that surrounds an end portion of the outer conductor of the coaxial cable. The crimp portion conforms to the corrugations of the outer conductor, thereby creating an interface with the corrugations that attaches the cable connector to the coaxial cable by maintaining an axial load between the cable connector and the coaxial cable. Additionally, the coaxial cable connector interface includes a sealing element and a protective boot for preventing moisture from bridging the interface and causing cable performance reduction.
