and 75&nbsp;ohm and 50&nbsp;ohm BNC connectors that comply with the 2007 IEC standard, IEC 61169-8,<ref name="IEC 61169-8">[https://webstore.iec.ch/publication/4753] Radio-frequency connectors – Part 8: Sectional specification – RF coaxial connectors with inner diameter of outer conductor 6,5 mm (0,256 in) with bayonet lock – Characteristic impedance 50 Ω (type BNC)</ref> will mate non-destructively. At least one manufacturer<ref name="canford-2">[http://www.canford.co.uk/Technical/Article/BNCConnectors Canford]. "In over 15 years and many million BNC connectors we have no first hand experience of incompatibility between 50&nbsp;ohm and 75&nbsp;ohm types, other than extremely rare (and very obvious) manufacturing faults."</ref> claims very high reliability for the connectors' compatibility.

At frequencies below 10&nbsp;MHz the impedance mismatch between a 50&nbsp;ohm connector or cable and a 75&nbsp;ohm one has negligible effects.<ref name="canford-1">[http://www.canford.co.uk/Technical/Article/BNCConnectors BNC Connectors], The Canford Group</ref> BNC connectors were thus originally made only in 50&nbsp;ohm versions, for use with any impedance of cable. Above this frequency, however, the mismatch becomes progressively more significant and can lead to signal reflections.
