Combining multi signals to tv's

beebaw

I want to combine all the 2 sky boxes, cctv, soarview, boxes together so that all of these can be viewed in all rooms,

So far i have put the RF 9v Out feed into the "0" port in the SPC4 Combiner, then i have a rf converter for the video output feed from cctv and it going to port "1" in SPC4 combiner, now out of the combiner and into a Tri_link, here i have the Soarview put into the scart feed, the Tri-link output is a 9v RF out so that it will send power to the magic eyes, this 9v Rf out now goes to the "RF in" on a Labgear 4 port splitter and then the various feeds to the house.

My problem is that the signal quality is very poor from the 2 initial feeds into the SPC4 combiner, but yet the signal from the soarview tri-link feed is crystal clear.

how can i improve the signal quality from the 2 SPC4 feeds (this is the Sky box and also the CCTV)

Which UHF channels are the Skybox & CCTV modulators using?

hi,

i am using channel 40 for cctv, 50 for soarview, and 60 for sky, i currently only have 1 sky box connected but would like to connect up a second also

thanks

You probably already know which channels to avoid but is the signal from the terrestrial aerial present on the feeds to the tvs for the analogue channels?

What part of the country are you in?

Did you check the quality of these before they're connected to the tri-link?

Does adjusting the tri-link gain control have any effect?

When tuning in the signal to the tv's there is a very slight terrestrial signal coming through, enough for the tv to think it is a channel,
i have tried the sky box and cctv using the tri-link input and the signal is perfect for these. Im sure it is something very simple but it is annoying when wathcing

In a lot of cases involving multiple devices, it's a matter of finding out which particular piece of kit is causing problems; trial & error basically.
