A connector for coupling a coaxial cable to an interface port comprising a capacitor segment configured to interpose a center conductor of a coaxial cable and an RF interface and an outer conductor segment extending over and electrically shielding the capacitor segment. The capacitor segment comprises an inner and outer pin having a dielectric insulator therebetween and is configured to electrically connect an inner conductor of the coaxial cable to the RF interface port. The capacitor segment facilitates the passage of RF energy from the inner conductor of the coaxial cable to the RF interface while inhibiting the passage of electric current through the capacitor segment to the RF interface.

An interface terminating device for an interface port includes, in one embodiment, a resistor having first and second conductive leads and a resistive element between the first and second leads. The interface terminating device includes a resistor holder and resistor engager which cooperate together to establish electrical contact with an interface port.

A surge-protected coaxial termination includes a metallic outer body, a center conductor extending through a central bore of the outer body, and a spark gap created therebetween to discharge high-voltage power surges. A plurality of dielectric insulators surrounds the center conductor on opposite sides of the spark gap. High impedance inductive zones surround the spark gap to form a T-network low pass filter that nullifies the additional capacitance of the spark gap. An enlarged portion of a center conductor mitigates deleterious effects of arcing. An axial, carbon composition resistor is disposed inside the outer body, and inside the dielectric insulator to absorb the RF signal, and prevent its reflection.

A radio frequency load for absorbing a radio frequency wave having a frequency in a predetermined frequency band and a wavelength comprises a waveguide with a portion having an opening for said radio frequency wave. In addition, the radio frequency load comprises at least one metal rod provided in said waveguide, said at least one metal rod having a length of one-half of said wavelength to damp said radio frequency wave.
