Its 75 Ohm impedance targets video distribution, broadcast, and telecom infrastructure where 75 Ohm cabling is standard, rather than the 50 Ohm world of general-purpose RF test gear. The dielectric is polyoxymethylene (POM) acetal. Maximum operating frequency is 4 GHz, which covers SDI video, baseband telecom, and most CCTV signals.","metaTitle":"Amphenol RF 031-218-75RFX BNC to BNC Adapter, 75 Ohm","metaDescription":"Amphenol RF 031-218-75RFX BNC plug-to-plug adapter, 75 Ohm impedance, male to male, straight, free-hanging.
