Using a 75 Ohm plug on 50 Ohm cable creates an impedance step that reflects signal energy. The 112954-10 is specced for 75 Ohm cable groups, specifically 1-1/2\" annular cable per the listing. The 4 GHz ceiling and 0.2 dB insertion loss are measured into that 75 Ohm line; swap the cable impedance and the loss figure no longer holds. ## Kit contents — what ships in the bag This is a field-installable kit, not a bare connector. Each package contains 5 pieces: one BNC plug body, one crimp contact, one ferrule, one insulator, and one sleeve. The PTFE insulator centres the pin in the body. No separate parts to order — everything for one termination is in the bag.","metaTitle":"Amphenol 112954-10 BNC Plug Kit, 75 Ohm, 4 GHz, Crimp","metaDescription":"Amphenol 112954-10 BNC plug kit, 75 Ohm impedance, 4 GHz max frequency, 0.2 dB insertion loss.
