Using a TV/satellite coax splitter

PeteW

There's currently a Virgin Media cable going under my living room to where the TV is. I'd like to also run a normal TV aerial signal to the TV. I've been unable to run a seperate cable under the floor, but I thought that I'd found a solution by using these diplexers/splitters.

From what I've seen, you should be able to connect the satellite cable and aerial cable to one side of the splitter and the cable on the other side should then contain both signals, which you can then split out at the other side. Is that right?

I tried it and no had luck - no signal on either the TV or the Virgin box. I tried removing the splitter at the TV side of things (so two wires going into the combiner, then a single lead coming out going to the Virgin box), but that didn't work either.

Anyone know if I am doing this all wrong, of if that should be working? Or any suggestions of how to get it working…?

Cheers

It doesn't work because Virgin doesn't use Satellite IF frequencies but uses UHF, the same as terrestrial TV.

You could try UHF splitter/combiners but if Virgin use the same channels as terrestrial TV you will possibly lose that Virgin channel AND a bunch of terrestrial channels as terrestrial is a muxed signal carrying a number of TV channels.

From one of the reviews of the Amazon device the OP gave a link to:-'This device combines aerial feeds from your satellite dish and terrestrial TV aerial onto one coaxial cable. IT DOES THIS BECAUSE THE FREQUENCIES ARE WIDELY SPACED APART and so can be combined without fear of interference. Make sure you connect the the satellite and TV feeds to the correct inputs - the LNB on the satellite dish needs to see a low DC voltage to switch the polarisation of each TV channel. One input of the combiner is designed to pass this DC - use this one for the satellite dish and the other for the TV aerial.'
Could you perhaps feed your aerial cable in through an external wall and run the cable around your skirting board or something?

It won't work with Virgin Media as their system is completely different and combines TV and bi-directional Internet down the same coax. Virgin Media cables between the street and the Virgin Boxes mustn't be altered by anyone except Virgin as it can affect the signal level not only to you but your neighbours.
