These are all 75 Ohm, small-diameter coax cables with a characteristic impedance that matches the connector's 75 Ohm design. The crimp termination covers both the center contact (pin) and the shield braid via the ferrule, giving a gas-tight connection that maintains the impedance through the transition. Using a cable outside this group will shift the impedance and degrade return loss — the fit is cable-specific. Rated to 2 GHz maximum frequency with 0.2 dB insertion loss, this plug holds signal integrity well into the UHF band. For a crimp BNC at this price point, 0.2 dB through 2 GHz is clean — it means the transition from cable to connector doesn't introduce a measurable bump in the signal path. The PTFE dielectric keeps the dielectric loss low and the impedance stable across temperature. The nickel-plated brass body resists corrosion in humid or salt-spray environments common in field-deployed video gear.","metaTitle":"Amphenol RF 31-71013 BNC Plug, 75 Ohm, 2 GHz, Crimp","metaDescription":"Amphenol RF 31-71013 BNC plug, 75 Ohm, 2 GHz max, 0.2 dB insertion loss.
