Are Neutrik BNC connectors true 75 Ohm connectors and are they suitable for HDTV?
Neutrik BNC connectors are true 75 Ohm HDTV connectors. With the introduction of HD signals the impedance of BNC connectors become more important than ever. Every deviate impedance has a negative influence on the “return loss” / “VSWR” (Voltage Standing Wave Ratio) which are important measurements for reflected signals in a transmission line. Especially on high frequencies – as they occur when transmitting HD signals (typical transmission @ 2.25 GHz) – an impedance mismatch results in a lot of return loss. Neutrik’s BNC connectors feature a true 75 Ω design that meets the stringent requirements of HDTV and sustain a consistent impedance at high frequencies up to 3 GHz. To achieve this result every Neutrik BNC connector has been adapted to the measurements of a small group of cables, this guarantees the best possible performance and a little return loss. The higher the frequencies the more pronounced is the “skin effect”, which means the energy moves to the outside of the conductor. The
