It's a 75 Ohm, right-angle, female-socket plug designed for field termination onto RG-179 or RG-187 coaxial cable. The kit includes four pieces: the connector body, an end cap, a crimp ferrule, and a heat-shrink tube, so you're not hunting for loose parts at the bench. ## Cable Prep and Termination Sequence This plug terminates with a solder contact and a crimp shield. The centre conductor solders into the beryllium copper pin (gold-plated), and the braid gets captured under the crimp ferrule. The heat shrink then seals the cable entry — important for keeping moisture out of the dielectric on outdoor or high-humidity runs. ## Electrical and Mechanical Ratings Insertion loss runs 0.6 dB through the mated pair, which is typical for an SMB at these frequencies. ## Construction and Plating Dielectric is PTFE (Teflon), which keeps the 75 Ohm impedance stable and handles the full temperature range without creeping.","metaTitle":"Amphenol RF 142194-75 SMB Mini Plug, 75 Ohm, RG-179/187","metaDescription":"Amphenol RF 142194-75 SMB mini plug, 75 Ohm, for RG-179/187 cable.
