The 413589-8: This is the video/broadcast impedance, not the 50 Ohm used in RF test equipment. The 500-cycle mating life means it's built for field reconnection — patch panels, camera cables, equipment racks — not a one-crimp permanent install.
Cable compatibility is explicit: RG-179, 179A, 179B, 187, and 187A. These are the 75 Ohm, 30 AWG solid/stranded centre-conductor cables with a nominal 0.100-inch dielectric diameter — the standard for broadcast video and CCTV runs. Termination is all-crimp: the centre pin crimps onto the conductor, the ferrule crimps over the braid and jacket. No solder, no clamp. The shield termination is crimp-only, which means a clean 360° braid capture without cold-solder joints. The free-hanging (in-line) mounting suits cable assemblies, not panel jacks.
The 2 GHz max frequency and 0.15 dB insertion loss suit broadcast video paths. The gold-plated centre contact and polyethylene dielectric maintain consistent impedance.
