Bit of tech help needed here
we've got an aerial in the loft which is connected to our tv downstairs and give a decent digital signal, it comes down through from the loft, into our bedroom then down to the living room.
We intend to split it in our bedroom and run it to the second tv, will splitting it reduce the signal as it would with an analogue setup?
If so, will it be possible to use a booster behind each tv, or does it need boosting where the split is? Or even in the loft at the aeriel end?

Splitting will reduce the signal.
I'd try it first of all then if you need one put a booster where it splits.

At the split not at the ends? The issue we have is power, the socket is the other
side of the room tithe aeriel so any booster would need an extension lead

You boost noise as well as signal so if you boost at the end of the line you boost more of the noise, that's not to say it won't work though.
I'd try with a normal splitter first and take it from there.

At the parents they have the signal coming from the aerial straight into an amplifier which splits it and sends it to all the points around the house.
Looks something like this:

Mains powered? Does that need to go near the aeriel?

Mains powered and as close to the aerial as possible.

You could fit a mast amplifier/splitter to the aerial, it would mean that you'd run another feed to the bedroom but the power supply (for the amplifier) could connect on the feed in your lounge. Although i can't remember if the PSU has to be connected to the amplifier within a certain distance, i'm also not too sure having the PSU so far away from the amplifier will cause excess noise etc.

Best way is to take the feed from the aerial into the loft and into an amplified splitter like the one above.
From that you take one coax to each TV point.
Use good quality cable (WF100) and keep the coax away from mains electric cables where possible.
This will ensure the best possible signal.
If you dont have a socket for the amp in your loft you can take it off the lighting circuit, you must make sure its fused to 3A max though, ideally through a fused connection unit.

I had a standard aerial in my house that cost me £65 including fitting, that ran two TVs in the upstairs bedrooms and the downstairs tv, all with freeview, every channel worked perfect. The fella tried to sell me a booster etc but I just took the gamble and it paid of with 3 seperate wires.

Split the feed from the loft into a 2 way junction box, put a new end on the downstairs coax to make it work, ran a new coax to the upstairs tv...
Worked fine for about 20 mins then lost all channels downstairs but it's fine upstairs still.
Tried swapping it over to the other socket to see if that worked but it doesn't.
I just don't get why it suddenly stopped after some time

Something must have came loose or moved somewhere.

or you have some of the insulation from the cable touching the cable itself on the cable you have ran downstairs
