Advice sought

Hi Guys, I'm new to the forum and was wondering if anybody could offer me any advice on the following.

My girlfriend has has the basic Sky+ box in her lounge and wants to be able to send the signal to her tv in the bedroom as the digital tv signal upstairs is very poor.
Are there any devices out there that can send the sky+ signal to her upstairs tv and allow you to change channels etc? Not having sky myself I have no Idea how these things work. Any help would be much apprieciated.

Cheers, JC;)

The easiest and cheapest thing to do would be to run a coax from the RF2 output on the Sky receiver to the TV in her bedroom, then fit a magic eye, this will allow you to operate the Sky receiver just as if it were in front of her.

Look on e-bay, you can get kits with all the bits you need for less than £20, maybe a little more if you want a second remote to save carrying it up and down.
