A tamper-resistant coaxial terminator includes an inner body rotatably captivated within an outer shield. A deformable portion of the inner body extends within an annular recess formed in the outer shield. An optional RF port, containing a resistor, is press-fit within the inner body. The RF port, or alternatively, the inner body, is internally-threaded for engaging the outer conductor of an equipment port. A seal ring extends over the outer conductor of the equipment port and is urged by the outer shield to directly engage the internally-threaded portion of the terminator. A seal is also optionally disposed between the outer shield and the inner body to minimize moisture induced corrosion. A shipping cap, usable at either end of the terminator, helps protect the terminator during shipment and prevents entry of debris.

An insulated cable attachment device, made of an electrically insulating material, is connectable to a termination connector which is in turn connectable to a tap port for a cable television system. When an installer disconnects service to a subscriber's house, the signal is shut down to the tap port to which the subscriber drop cable is connected. The drop cable is disconnected from the tap port and a terminator connector is connected in its place on the tap port. The installer then installs the insulated cable attachment device onto the terminator connector before connecting the drop cable to the insulated cable attachment device, thereby preventing any difference in ground potentials between the terminal connector and the drop cable from being transmitted to the end of the drop cable near the house.
