It terminates RG-179B and RG-187A cable — the 75 Ohm impedance matches the characteristic impedance of those cable types, so the signal sees no reflection at the connector interface. The plug ships as a three-piece kit: the connector body, the center contact, and the ferrule, ready for field or bench assembly.
RF Performance and Termination
Rated to 2 GHz with a typical insertion loss of 0.2 dB, this BNC plug holds the signal clean through the upper VHF and into the lower microwave band — adequate for HD-SDI video, baseband telecom, and instrumentation links. The center contact is gold-plated brass, soldered to the cable center conductor; the shield is crimped using the included ferrule.
Mating and Mechanicals
Bayonet lock fastening — a quarter-turn mates or unmates the plug with any standard 75 Ohm BNC jack. Rated for 500 mating cycles, which is typical for field-serviceable BNCs; the gold center contact plating prevents wear and oxidation at the signal interface over repeated connects.
No official second-source cross-reference exists, but the 415420-1 is a functionally similar TE BNC plug in the same Greenpar family — confirm the cable group and impedance match before substituting.
