That impedance is the standard for video — SDI, HD-SDI, and composite video runs — and for cable TV distribution. Using a 50 Ohm BNC in a 75 Ohm path creates a mismatch that reflects signal and degrades the picture. The 034-1028 is the correct interface for any 75 Ohm coax like RG-59, RG-6, or Belden 1855A, though the specific cable group is not listed for this part — the solder termination on the center contact and shield means you terminate the cable directly to the connector body. ## Mounting and Termination — What Ships in the Box The package includes two pieces: the connector body and the bulkhead nut. The center contact and shield are both solder-terminated, so you need a soldering iron and the right cable prep. No crimp tool required. The through-hole mounting style also has solder posts on the rear for PCB attachment if you are landing it on a board rather than a cable. The 034-1140-12G is the 12 GHz-rated sibling in the same HD-BNC series, also 75 Ohm, but with a nickel/gold body finish and a bagged package. The 034-1028 tops out at 4 GHz, which is enough for HD-SDI (3 Gbps) and most broadcast video. If your signal path runs beyond 4 GHz — 12G-SDI or higher-rate serial video — the 034-1140-12G is the correct choice. For standard-definition and HD video up to 3 Gbps, the 034-1028 covers the job without paying for the extra bandwidth.","metaTitle":"Amphenol RF 034-1028 BNC Receptacle, 75 Ohm, 4 GHz, Bulkhead","metaDescription":"Amphenol RF 034-1028 HD-BNC receptacle, 75 Ohm impedance, 4 GHz max, panel mount with bayonet lock.
