After several years with a sky dish, my parents asked me to do something with their old aerial setup. The aerial, high up on the gable was a perfect perch for the local pigeons to sit and make a mess on their doorstep.
They have a Panasonic tv in the living room, connected with a sky+ box, and a Sanyo in a bedroom... with a wii connected to it.
Ive got one of those £15 signal detectors from screwfix. 5 green lights to signify strength.
Took the old aerial down and pulled out the old brown coax from 1987.
I fitted a rather large 'hi gain' aerial in their attic and pointed it at a best guess direction. Signal detector showed a just barely 1 green light - not great. I made up a trailing lead, ran it out the hatch to the bedroom and plugged it into the telly. Autoscan picked up 60 channels, which is pretty good for the region we live in. Pretty happy.
I continued to run new screened coax from the attic down the outside and drilled through into the bedroom and living room.
Job finished... bedroom tv still picking up 60 channels... living room only picking up BBC channels?
I didn't have time today to check the connections, or trying the upstairs tv downstairs and vice versa. I'm pretty sure I read somewhere that the different brands of tv use different tuners, and some are better than others with weak signals. is this true?
I'll try a simple 2 output amplifier and see if that helps.
 
Samsung tvs have traditionally required a bit more signal than most but this is marginal.

There is no substitute for collecting the maximum amount of signal available. Aerial location is paramount. Blind amplification is just as likely to destroy the signal as help it (it will amplify the unwanted 'noise' as well as the wanted signal
 
The splitter is located in the attic. I think it is a satellite signal splitter as it has a 'power pass'(?) diagram on it. Its the living room feed connected to the powerpass output.
Ive not had time yet to swap over the TV's, or the outputs to the splitter... just to clarify whether it might be a cable.
One thing I didn't mention was the living room cable is connected into an old wall point. Then a new lead from wall to TV. The bedroom is directly into the TV.

Other day had too much signal , causing sound breakup .
Got better as unplugged aerial lead !
( Need to know way around some device menus to even find a
signal level )
....Some signal levels are creeping up ! (especially if amplified)

Which is one of the reasons why you don't amplify unless you know you need to.

It is very rare to get too much signal off air (unamplified).
