With the patented InSITE Technology feature, now standard on all IDEAL RG-11 compression connectors, field termination of these blind entry connectors is simpler, faster and now provides a higher performance connection for all applications from CCTV to HD Video. The InSITE window is a 360° clear window which allows the installer to verify that the prepped cable has been inserted far enough into the connector to make contact with the fixed pin-before the connector is compressed. Features RG-11 or RG-11 Quad Plenum sized connectors are available for use in applications and installations from 5MHz to 3GHz, including CATV and satellite trunk/distribution lines. An internal sealing compression sleeve prevents moisture from entering the backside of the connector and aides in cable retention Nickel-plated brass construction provides corrosion resistance Weatherproof for indoor and outdoor use Recommended compression tool: 30-793 OmniSeal PRO XL Requires a standard 1/4 in. x 1/4 in. cable preparation Dielectric diameter range: 0.270 in. - 0.280 in.
