Optical to Coax

[Fishermanpaddy]

Hi folks,
I had a sattellite installed the other day to use with a freesat box. the wires were set out so that the sattelitte wire goes down into my living room into the lnb in in the freesat box, out of the lnb out and back up to the loft into a splitter for 5 rooms.
The trouble is that the lnb out in the box does not work, (i know its not the wiring because iv tested it with a skybox and it works fine). So my question to those of you who are knowledgeable in this field is that if i use an optical cable out of the back of the freesat box and use an optical to coax converter (iv seen one in maplin but i am unable to post links)
optical to coax converter, will it be sufficient to fire the signal into the loft into the splitter box and into each designated room?

I should mention that there are several outputs on the back of thr box (humax foxsat) and if the method that i have explained will not work, is there any other way (short of buying those annoying video senders) to loop the signal.

Many thanks in advance folks.

P.s here is an image of the intended converter

im just realisinf that tis is for audio, but can you get one for picture also?

You cant use lnb splitters of any kind - you need independant runs of cable from the dish to each receiver.

The lnb is an active device - its powered by the box. More than one box on a line interferes with the electronic switching.

You have it completely wrong.

You don't use the LNB out wire to supply multiple receivers with a splitter. It is for generally another receiver alongside.

To achieve what you want, you should fit a an Octo LNB and run separate cables to each room, or a quattro LNB and fit a multiswitch in the loft, and then run a cable to each room from that.

Forget the optical stuff, it won't work either.
