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, shielded CATV balun allows broadband CATV equipment to be integrated into structured cabling system thereby allowing CATV equipment to be moved or added to any convenient modular wall outlet. When used with shielded twisted pair cable, connection supports greater RF ampliflication and therefore greater distance with less EMI/RFI egress versus CATV Balun II (500302).
