TV Aerial signal distribution - what do I need etc?
Right.....
I need to move the aerial socket in my living room as SWMBO wants the room changed around 
I'm planning to start in the loft and re-route cable down through a fitted wardrobe and cavity wall to a new wall socket.
Then I started thinkig that while I'm doing it it would be worth fitting some kind of splitter in the loft and wiring in proper sockets in 2
bedrooms and down to the conservatory. The physical wiring is easy enough as most internal walls are dry lined, but what do I need in terms of
hardware?
1. Powered 4 way FM/DAB/UHF splitter - is it worth getting one with F link threaded connectors? or are these only for satellite?
2. Reel of decent co-ax cable
3. Wall plate sockets
4. Any thing else?
Input please 
(Thining on from this Iwas wondering about putting in CAT5 cabling for a network too  )

A socket in the loft to supply the amp (powered splitter).
Tell them about the bent treacle edges!

We originally had a 4 way Aerial amp feeding 4 rooms but changed to two seperate loft TV aerials, each with its downlead split into two by a
non-powered splitter. This avoids having an amplifier powered 24/7 in the loft or a cupboard.
We are a bout 12 miles from a very powerful transmitter on which we have line of sight hence have good reception. I just have simple loft aerials for
TV & FM which share a down link going to two rooms via a simple (ie non-powered) splitter, FM is split from TV at the wall plate, this works well
-- in fact I found I got better FM and Freeview reception by fitting 3db attenuators at the the wall plate.
With a non powered splitter you get losses, how much you can split the signal without boosting will depend on how good your aerial and how good your
reception.
The other way to split he signal is use an amplifier --- Asda used to/may still sell good quite ones reasonably cheaply. Look for one with variable
output some Freeview boxes don't like over boosted signals.
With aerial amps avoid Micromark

I'm about to do something similar, except I'm running to more rooms than you.
I'm going for a Triax DDU 112, which works out around £70 or so. You feed all your aerials into it, and it amplifies them as necessary, before
feeding the signal down to your main TV point. You can then add more signals to that (say Video, Sky+ etc) and feed the signal back up to the Triax in
the loft, which then distributes *that* signal to all the other points in the house. Means you can do stuff like watch the video recorder in your
lounge from your bedroom.
As with any of these things, use the best quality coax you can get, especially if you have long runs. The stuff from B&Q and the like is pretty
cheap and nasty. The places that sell gear like the Triax will also be able to sell you good quality coax too.
Cheers
