Extending cables - advice please?

[bigtired]

Hi, Hope this is in the right forum.

I want to move my TV to the opposite corner of the lounge. At present I have a terrestial co-axial cable, and a sky cable coming in through the wall, and then a co-axial cable going out through the wall up to my bedroom (using the spare RF out on the Sky plus box) so I can watch Sky upstairs (I have a magic eye to switch channels).

I want to avoid having to have a reinstallation of all the cables if possible.

Where I want to relocate the TV etc is on an internal wall anyway. I also keep on changing my mind about the layout so I may want to move the bloody TV again!!

Is there any way that I can effectively extend the cables (circa 20 ft or so) without screwing up the quality of the signal. I have thought about leaving all the av in the same corner and then have some crazy length scart lead to the TV but I don't know if they make them 20 ft + long.

Any advice appreciated.

Thanks

Justin

I have had the following advice from an internet company.

Satellite Inline Amplifier

Connectors and cable to extend the sat and aeriel cables. They don't suggest an amplifier for the aeriel.

What do you think?
