Have a rooftop aerial and couple of cctv cameras going into a booster.
Occasionally picture is good but most of the time its rubbish.
Either plugged in separately works ok.
I'm now getting hassled off the rents to get the picture sorted.
I can't think of any other way to combine the signals apart from a better quality y splitter.
Ran out of things to put into google to try and get help.
Any ideas or any sites I can look at?

from what i remember you cant just use a y-splitter to combined the signals you will need to modululate the two source together, otherwise it causes interference - can get a modulator at maplin's but i dont think there that cheap.
Would be simpler to run the CCTV feed sperately and distrubute it to the tvs that need it

It will be just running them into the y-splitter that is causing the interference.
Even i'll just have to see if there is anything that does the job properly.
Its a hassle to change all the wiring or i'd run everything properly with higher quality stuff for a start.
Cheers though.

normally, you can use a capacitor (condensator) to do the job...
connect the axial bit from each cable through the capacitor tips...the rest (around the axial bit) connects...but the 2 should be isolated properly...i do this for my different tv axial cables...
but i don;t know the range of capacities you would need

Hmm would act as a filter.
Good idea.
I've slightly tweaked the channels the cctv feeds are showing on and it seems to have done enough to get them off my back for a bit till I can be annoyed doing it.
