In summary, Amphenol RF, the inventors of the BNC, looked towards the future in creating the HD-BNC™ to meet the HD demands of the broadcasting industry. HD-BNC™ delivers true 75Ω performance in a footprint that is 51% smaller than traditional BNC connectors, allowing four times the density. The HD-BNC™ meets SMPTE 292M & 424M standards, with both its return loss of 1.04 at 3GHz and its insertion loss of 0.10 dB at 1GHz.
