This plug is designed specifically for RG-178B cable, a 50 Ohm, low-loss, double-shielded coax with a stranded centre conductor and FEP jacket, often used in tight-bend, high-density RF harnesses. The right-angle body keeps the cable exit parallel to the mating axis, saving space in enclosures where a straight plug would interfere with the lid or adjacent components. Termination is a two-step process: solder the centre pin to the cable's centre conductor, then crimp the shield ferrule over the braid.","metaTitle":"MMCX-LP-178B/U MMCX Plug, RG-178B, 50 Ohm, 6 GHz, Gold","metaDescription":"MMCX-LP-178B/U MMCX plug, male pin, right-angle, for RG-178B cable. 50 Ohm impedance, 6 GHz max, gold body.
