R.F. CONNECTORS & ADAPTORS

VIDEO/BROADCAST SPECIALTY CONNECTORS & ADAPTORS

BNC 75 OHM CONNECTORS

Communications systems are becoming more demanding and are requiring high performance, impedance matched cable interconnections. We have offered true 75 ohm performance connectors for some time and now are greatly increasing our breadth of products. These units are needed to insure proper impedance matching which is required for broadcast, Post Production, CATV, MATV/SMATV, Audio/Video, Multimedia, Computer, CCTV, Security and Home Entertainment applications.

The goals of our connector designs are to provide reliable performance in the various environments where signal integrity is required whether the circuitry is analog or digital. The broadcast industry faces many challenges and the correct selection of reliable, quality cabling and interconnect products will determine if the audio, signal or video transmissions will maintain clarity and prevent downtime. As broadcast and the many associated industries prepare to meet the new demands, the selection process becomes much more difficult for the design engineer, systems installers and the contractors. Too often product is selected on appearance and price, rather than proven specifications and performance history. We have been providing connectors, adaptors and accessories for thousands of designs year after year and protected systems form failures. Our products are designed for the most popular 75 ohm cables and are suitable for rack systems, CCTV systems and equipment signal connectors.
