I bought a Phillex SLX1 1 way signal booster to help me get freeview. I currently have the roof aerial plugged into a sky box, the output of this is split into 4 and goes into rooms around the house and my room (long cables).
I plugged a short wire from the booster (output) to the TV in my room and plugged the long cable into the booster (input).
When using the booster I am getting a rubbish signal, all the terrestrial channels are worse and i'm not getting a signal at all on freeview.
Without the booster the terrestrial channels are fine and I get a low signal on freeview.

There is a gain control on the booster, when I change this nothing changes to the picture on the screen, the picture is full of static and the sound is crackly.

Does this sound like a broken signal booster or have I done something wrong?

Thanks
 
If I could understand your post it would help.

You say you plugged the long cable into the booster input. Where does this long cable originate?

Also, how have you split the signal?

What RF channel is your sky box outputting at?
 
can you get a freeview signal when connected directly to the aerial?

Remember that a booster will boost everything, including crap in the signal that you don't want.

Sorry about that, just read it back and it is quite confusing.

I just done this diagram to help explain it better. The cable from the sky box to the splitter is very long, this is probably causing the signal loss.


The splitter is just a white box with one input and 4 ouputs (from memory). Not really sure about the make/model as I can't see it as it's in the attic.
Sky is outputting at CH68, 847.25mhz. Not sure what RF channel means but this is all the details I can find.

If I plug the aerial in directly (no boosters, extensions, sky box etc)I recieve most of the freeview channels with a good signal. Unfortunatly I can't keep it like this as the cable from the roof aerial is downstairs and the freeview box will be kept upstairs.
Without the booster and freeview connected with extensions, sky box etc, I recieve a signal but it's so low it's unwatchable.

I think putting the signal booster where it is in my diagram should have fixed it but it's hasn't, when it's plugged in it's making the signal worse instead of better.

Sorry I can't explain very well, not very good with cabling and TV's.
I might just forget about it and get a professional in to sort it out.
 
I would put the booster just after the sky box so the signal is boosted prior to the splitter and the long cable run. This will improve the picture on all the TV's then :)
