The 50 Ohm impedance is a straight match for the listed cable groups — no impedance bump at the transition if you follow the manufacturer's crimp dimensions. ## Field Termination Kit Contents Each 31-321 unit includes four pieces: the BNC plug body, one crimp contact, one ferrule, and one PTFE insulator. The crimp contact and ferrule are sized for the RG-59/62 cable group — no separate die selection needed for the common types.","metaTitle":"Amphenol RF 31-321 BNC Plug, 50 Ohm, 4 GHz, RG-59/62 Kit","metaDescription":"Amphenol RF 31-321 BNC plug, 50 Ohm, 4 GHz max, 0.2 dB insertion loss.
