The 034-1037 is specified for RG-122, RG-180, RG-180A, RG-180B, RG-195, Belden 1855, and Belden 1865A cables. These are all 75 Ohm coax types with a nominal impedance match — using a different cable group will shift the impedance and degrade return loss. The crimp ferrule is sized for the outer jacket diameter of these specific cables, so swapping in a different coax means the ferrule won't bite correctly. ## 75 Ohm vs 50 Ohm — what's the difference? This is a 75 Ohm connector, not the more common 50 Ohm BNC. The impedance is set by the dielectric geometry and center pin dimensions — a 75 Ohm BNC has a smaller center pin than a 50 Ohm version. Using a 75 Ohm plug on a 50 Ohm cable or vice versa creates a mismatch that shows up as ripple in the passband and reflected power. For video (composite, SDI, HD-SDI) and broadcast reference signals, 75 Ohm is the standard. For RF test equipment or radio, you'd want a 50 Ohm BNC. ## Field life and temperature range The PTFE dielectric holds its dielectric constant across that range, keeping the 75 Ohm impedance stable.","metaTitle":"Amphenol 034-1037 BNC HD Plug, 75 Ohm, 4 GHz","metaDescription":"Amphenol 034-1037 BNC HD plug, 75 Ohm impedance, 4 GHz max frequency.
