The TE Connectivity 1-1478046-0 is a Greenpar-series BNC jack-to-jack adapter, a straight female-to-female barrel that passes a 50 Ohm signal path through a panel. This is the adapter you spec when a coax run needs to break at a panel or bulkhead without introducing an impedance bump.
50 Ohm Impedance, 4 GHz Bandwidth — The RF Specs That Matter
The 4 GHz upper frequency covers the full L-band, S-band, and lower C-band, which means it handles GPS, Wi-Fi, cellular backhaul, and most radar IF signals without rolling off. The 500-cycle mating life is typical for a BNC bayonet interface; the silver-plated brass centre contacts hold up to repeated connect-disconnect in test-rack or field-service duty better than a tin-plate alternative would.
Panel Mount with Bulkhead Hardware — Installation Checklist
The adapter mounts through a panel cutout sized for a standard BNC bulkhead — the lockwasher sits on the outside face, the nut tightens from the inside, and the connector body stays fixed while cables mate on either side.
