CATV Balun II 500302 ___________________________________________________________________________________________ Overview The CATV Balun II (500302) allows traditional 75-ohm coaxial cable to be replaced by a single pair of Cat 5 UTP cable in the CATV, VHF and FM environments in certain applications. Used in pairs, the CATV Balun II allows broadband CATV equipment to be integrated into structured cabling systems thereby allowing CATV equipment to be moved or added to any convenient modular wall outlet. The CATV Balun II provides a versatile cabling solution for broadband video systems used by schools, government, offices, hospitals, financial institutions, hotels and residential complexes. The CATV Balun II works in conjunction with RF splitters, combiners, amplifiers and cable modems for a total cabling solution. Benefits Supports broadband Internet and digital cable Eliminate costly coaxial cable Quicker moves, adds and changes Neater wiring Features High bandwidth – up to 900 MHz Low insertion loss Compact design Specifications Environment: Private and public broadband CATV, VHF and FM networks.

In some applications, a “tilt” amplifier may be required since the UTP losses are higher than coax at the higher frequencies. Linear gain compensation of up to 2025dB at 750MHz is usually adequate. Conversely, if amplification is used to compensate for losses at higher frequencies and long distances, it may be necessary to attenuate the lower frequency, shorter distance signals to avoid over-driving the TV monitors.
