splitting a sattelite signal?

[bampy]

I just bought a freesat box, connected it to the sat cable, via a splitter box, only one outlet being used. The message on screen was "no signal" I was baffled by this as I had seen the box working earlier in the day at another address. I reluctantly called out a sat engineer, who promptly put a straight single connection on the cable, and hey presto it worked.
How does the box know its being fed from a splitter?
Is there a way around this, as I would like to run the cable to another room, for an additional box/tv setup.

The engineer told me that The lnb at the dish would have to be changed at a cost of £135.

Splitting the signal weakens it, that is the problem. The "engineer" is over-quoting. What you need, for more than one receiver, is a quad LNB, fitted, instead of a single one. This gives you up to 4 connection points to run cables from for independent digiboxes. If you only have one, you do not need a splitter box.
