CATV Balun II 500302 - Surveillance
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.

Typical Application:
In a point-to-point scenario for CATV (superband and hyperband), VHF and FM, cable lengths of up to 50 meters may
be achieved without amplification if the nominal input is about 15dB. 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.
