Boosting A Split Signal

[LLcoolDave]

So I've got my line split 3 ways at the moment (2 receivers and the router) as a result the signal has weakened.
Any amplifiers on the market that are worth going for?

This is the one i bought. Konig Professional TV Amplifier 26db and it worked on my cable box.

Used to have that issue in the past when I had a 3 way splitt, take a look at the Technetix HDU-400. there the ones virmin engineers use.
