Shielded CATV Balun
The Shielded CATV Balun (500306) allows RG6 coaxial
cable to be replaced by Cat 5e/6/7 STP or UTP cable in
the terrestrial RF environment.
Used in pairs, the
Shielded CATV Balun allows broadband CATV equipment
to be integrated into a structured cabling system thereby
allowing CATV equipment to be moved or added to any
convenient modular wall outlet. When used with Cat
5e/6/7 shielded twisted pair cable, the connection
supports greater RF ampliflication and therefore greater
distance with less EMI/RFI egress versus other UTP
CATV baluns. The Shielded CATV Balun also works in
conjunction with MuxLab’s CATV Hub (500300/303) for a
total cabling solution.
Schools, government, offices, hospitals,
institutions, hotels and residential complexes.

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 STP/UTP losses are higher than coax at the higher frequencies. Linear gain compensation of up to 20-25dB 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
