The ATX Network TSB-31G/B is a 3-port RF splitter with a digital-ready broadband frequency range of 5 MHz to 1000 MHz. A solder-back cover-plate provides maximum EMI-RFI shielding > - 130 dB, eliminating signal ingress to guarantee distortion-free pictures. TSB-G series splitters feature a capacitor coupling circuitry at all ports for effective DC voltage blocking.
