I can build anything you want if you draw a picture of it on the back of a big enough check.
There's no substitute for hard work....but that doesn't mean I'm going to give up trying to find one.

In frustration one night I googled "bidirectional video amplifier" not knowing such an animal existed, and there it was! I ordered one, got rid of all the splitters, and ran home runs back to the closet for each drop.
And that's when I came to find out that cable TV termination is real; until I terminated all the open ports, the dialog between the cable boxes (I now have two of them) and the mother ship was very undependable, and some channels would not work at all.
I did some looking on line, and I read about termination and the problems that lack of it can cause, so I bought a box of terminators and installed them everywhere I could. Problem solved.
