Careful choice of UHF channels and more importantly good quality coax and tight coax plugs and you should not have problems with loss of signal until you get more than 5 serial items in your chain. There is no easier way to do it. Anything else involves multiple wires or really fancy hardware at the sending end to only put on 1 UHF channel the thing you want to watch.

Some splitters are symmetrical, i.e. they can be used as combiners. I've seen really cheap splitters that use just resistors, but most of the ones lately use baluns to split. These balun types should work as combiners. But I don't know how much of the signals from the other three feed back into each source. The nice thing about this, tho, is that it's inexpensive to buy a four way splitter and try it out. You might even find one along with some coax pigtails for a dollar or two at a garage sale or a thrift shop.

That's probasly not going to happen, because there may be blocking capacitors inside the splitters, or worse, the spltter is a DC short across each of the coaxes.

Maybe something from this page will help you out... They are a bit spendy but I've installed them in several homes with great success. Notice the

If you don't want to spend that much here is something I learned not long ago. Apparently you need to balance the signal inputs to your splitter/combiners. If you are lucky enough to have your STB or modulators say what level dB signal they are outputing, try inserting an attenuator or two inline before the combiner. Say a 3dB or a 6dB. They can be found here...

As far as sending 10V over coax... a lead you can chase is this link...

My thanks for your comprehensive reply. Maybe when I have sobered up (from new year) it will make more sense!

Thanks again,
