I'm shuffling things around a bit in my home office and need to extend the incoming cable from the internal junction box to the modem unit by about 4 metres.Virgin want £99 to do this ten minute job!
Is there any way I could do it myself or is there anyone out there who's qualified to do it at reasonable cost?(Bolton,Lancs area)

You need a length of good quality (satellite) coax able, two F Connectors and a Female/Female F Connector. (If you don't feel up to making the connections, you can buy lengths of cable with the F Connectors already fitted.)

Screw the F connector at the end of your Virgin box into one side of the Female/Female and the new length of cable to other side - Bingo!
