Been a long time since I've done anything with coax. Used to run a coax computer network and did lots of 450 and 800 mhz 2-way radio stuff BITD.
Those splitters are not great, especially without terminal caps for the ones not in use. When we used them (long coax runs for 800mhz trunk radios) we needed powered signal boosters to make them functional. This maybe what is happening here - simple signal deterioration.
Maybe cheaper to replace and see what happens?
Aroogah-
Cheers. I remember aerial boosters being all the rage when I was younger but never really knew whether they actually worked. Maybe something like this would do better

When I moved into my house it had been all wired up for a tv aerial with aerial points in each room and one of these under the stairs linking it all to the aerial wiring in the loft:
There wasn't an aerial installed but I traced the wiring up to the loft using one of these and connected an aerial.
It doesn't work. The aerial does work (I put a wire down the chimney breast and connected it to my tv and it works fine) so it must be somewhere in the wiring which has a fair few joins (but still shows continuity from the downstairs aerial point to the wiring in the loft).
Any suggestions for tracking down where the issue arises that doesn't involve me wiring up a freeview box and screen at each join to see where it stops working? Cheers
