Using an unbalanced splitter is useful if splitting a coaxial cable between one modem and several televisions as the televisions don t need as much bandwidth. Extreme broadband bds103vfb 3 way balanced digital splitter vertical flex mount true flex rg6 coaxial splitter. Extreme broadband manufacturing bda103hb 3 way balanced hd digital 1ghz high performance coax cable splitter. Balanced cables and signals.

A ground a positive leg and a negative leg. As in the unbalanced cable the ground wire still surrounds the signal wires and is used as a shield against interference. Unbalanced splitters by contrast have odd numbers of output ports some of which have less signal loss than others.
