The SuperLok® series RCA compression connector by Holland Electronics utilizes two independent compression points to seal and hold the coaxial cable to the connector. Other compression type connectors employ only one point for both, which requires extensive compression of the cable jacket to achieve the same goal. The SuperLok’s patented first stage compression/locking method, in use for over 8 years, insures the highest holding force. RPS has tested many types of RCA style compression head connectors and the Holland SuperLok® series are the ones we recommend and the ones we use in the field. This model is made to be used with RG-6 cable.
