The 75 Ohm impedance sets this apart from the more common 50 Ohm SMB variants. It pairs exclusively with 75 Ohm cable and 75 Ohm equipment — video distribution, broadcast, CCTV, and some data-acquisition systems use this impedance standard. The PTFE dielectric maintains consistent impedance through temperature swings. Insertion loss is 0.3 dB — low enough that a single mated pair adds negligible attenuation to a video or RF signal path. ## Crimp Termination — Shield and Centre Contact Termination is crimp for the shield and either crimp or solder for the centre contact. The ferrule crimps over the RG-179 double braid shield; the centre contact can be crimped or soldered to the signal conductor. The heat shrink tube slides over the ferrule and cable jacket for strain relief and environmental sealing.","metaTitle":"142187-75 SMB Plug, 75 Ohm, RG-179, Crimp Kit","metaDescription":"142187-75 SMB mini plug, 75 Ohm impedance, for RG-179 double braid cable.
