I have Time Warner Digital Cable and since move to we new place we signal have be a issue . we have two digital box and Time Warner refuse to boost the signal so we could hook up cable to additional tv use a coax cable . before this product try to do so kill the signal to one of the digital box . in addition , the box whose signal would get kill by other source would lose signal for high def channel from time to time with no split . I order the booster and the Ohm terminator and it work like a charm . not only be we able to watch cable on all we tv with no disruption , but the picture on both digital box be crisper than before . all channel on both box work and I no longer have to constantly reboot my digital box . I be so glad I give it a try .
