I am moving the telephone wall socket in my study because I'm
often checking out some extra phone device and need better
access than a single socket at floor level. A simple extension
lead may not work too well because they don't usually have
twisted pair wiring, so I'm told they can pick up interference
and I have enough interference on the line anyway.

I need some advice on positioning the sockets.

I was going to put in a double socket (two double sockets
actually) about 10-12 inches above the level of my desk. Any
devices I am looking at would be able to rest on the desk.

The master socket is in another room so these are all extensions
sockets wired in parallel.

I chose a height of 10-12 inches above the desk because if the
socket was too low then any phone plugs and adaptors which stuck
out might jostle with papers, books and desk things.

One problem for the new sockets in this position is that an old
style PC monitor (CRT) would be about 2 feet away. I really want
to avoid creating line noise so do I need increase this
distance?

On the other side of the sockets are flourescent light fittings.
Some are compact flourescent bulbs and there is a 20 inch long
strip bulb too.

Any thoughts on positioning. Sensible ones please (the ceiling
isn't going to work!)
