Video Splitter, 4 way Legacy, NTSC/PALA common mistake made in video cabling is the use of widely available BNC T connectors to distribute a video signal to multiple receivers (monitors, transmitters, VCRs, etc). This creates problems due to the 300mV reduction of signal strength incurred with each additional receiver a reduction which results in a progressively dimmer picture, as well as the mismatched cable impedance resulting from multiple 75 ohm terminations on a single line something
