Rated operating temperature is -65°C to 165°C. ## CCTV and Video Signal Path — Why 75 Ohm Matters The 034-1021's 4.5 GHz bandwidth covers the full HD-SDI data rate (1.485 Gbps) and 3G-SDI (2.97 Gbps) with margin. If you are wiring a CCTV head-end or a broadcast rack, this connector keeps the return loss low through the patch panel. The shield termination is solder, so you get a solid 360° bond to the cable braid — no crimp-on ferrule to corrode or loosen over time.","metaTitle":"Amphenol RF 034-1021 BNC HD Receptacle, 75 Ohm, 4.5 GHz","metaDescription":"Amphenol RF 034-1021 BNC HD receptacle, 75 Ohm, 4.5 GHz max frequency, 500 mating cycles, gold body, through-hole, bulk.
