cabling question

ZygOte

While moving furniture around the place ive moved the tv from one side of the room to the other. the tv and decoder were right beside the NTL point on the wall now that ive moved them i needed to run a cable along the skirting around the wall to where the decoder is now. im using a bog standard RF 10m cable with F plug on one end (into the NTL point) and the normal RF type on the other end into the ntl decoder. basically my problem is that my anologue singal is now slightly poorer (i think, it was never very good) but the digital doesnt seem to work properly at all. im getting less than half the channels coming in and they are quite jerky and stall. im assuming im loosing the signal over the cable length.

should i be using better cabling (like the crazy expensive monster stuff?), boosters etc? how can i get the signal to go the extra 10meters? i also noticed putting an F splitter in the cable kills the signal aswell. the signal must also be weak coming into the house?

Using splitters works best when the signal you're splitting is already quite strong. Using higher-grade cable would help and have as few connections as possible. If this doesn't solve the problem, try a booster with a variable attenuator to allow you to choose how much the outputs are amplified -- too much causes all sorts of problems. It can't work miracles (especially on digital) but it could help the analogue.

can anyone recommend the specific cable type and standard i should be using ?

You would be better off getting UPC/NTL out to move the cable for you. I think they charge about 50 euro to move a point. At least then if you ever have any problem you can call them to fix it.
Otherwise you will need some RG6 cable and some f connectors.
