The screw terminal balun is used in pairs to transmit standard composite video and supports transmission of color signals up to 1200' (365m) via Cat3; it can be extended to 2200' (670m) via Cat5. For black and white signals, the maximum transmission distance is up to 1500' (457m) via Cat3 (can extended up to 2500' (762m) via Cat5/6). The balun uses 2 screw terminals.
Made of ABS fire retardant plastic, the compact screw terminal balun measures 2.30 x 0.62 x 0.62" (5.8 x 1.57 x 1.57 cm), and features low return loss that ensures maximum power transfer with no line faults between the input and output. Besides using Cat3/5/6 as a cost-effective alternative to coaxial cabling, the balun also makes changes or additions to modular outlet connections faster and easier.
