I am thinking of moving the modem to a different location and would need a longer F cable. Do I need a 50 ohm of 75 ohm cable?
Alternativly, what is Virgin likely to charge to move the point to a new location?
My advice is always get Virgin to do it which will cost you around £99.
however I know you will think it is a rip off and won't want to pay so make sure you get the right cable I would suggest spotting a virgin tech and asking for a small length.
Thats a hell of a lot to my mind. I think I'd rather run an extension cable round the room, so 50 ohm or 75 ohm?
75 WF100 is what I would use, but RG6 might work.
If you mess up the connection for everyone in your street then the £99 fee would have been worth it.
You can get Attenuation sheets for all cable you buy too, no clue what the stats are on the stuff VM uses.
If your using a modem with a router then I would just run Ethernet.
