Rated to 6 GHz, this connector covers the full L-band, most ISM bands, and common wireless backhaul frequencies before the VSWR climbs. The gold-plated phosphor bronze centre contact and nickel-plated brass body give it corrosion resistance for outdoor or industrial cabinet runs. ## Cable Prep and Termination Sequence This plug uses a crimp shield termination and a solder centre contact — a two-step assembly common on LMR-195. ## Why 50 Ohm and 6 GHz Matter for This Cable LMR-195 is a 50 Ohm cable with about 6.8 dB/100 ft loss at 1 GHz. The 034-5079 matches that impedance exactly, so there is no reflection at the connector-to-cable junction. The 6 GHz ceiling is the practical limit for this interface — above that, the BNC HD geometry starts to radiate. Compare this to the 034-1118-12G, which is a 75 Ohm BNC HD plug rated to 18 GHz for Belden 1855 A cable. If your system is 75 Ohm or needs the higher frequency headroom, that peer is the correct choice; for standard 50 Ohm LMR-195 runs, the 034-5079 is the direct fit.","metaTitle":"034-5079 BNC HD Plug, 50 Ohm, 6 GHz, LMR-195, Active","metaDescription":"034-5079 BNC HD plug, 50 Ohm, 6 GHz max, mates with LMR-195 cable.
