Our arial enters the loft, then is split to 4 locations in the house. As such, the signal is chuff.
In the lounge I've popped a simple booster there, but ideally i'd like to boos closer to the source.

Is anyone here a TV whizz, and can reccommend a decent 4 way booster/splitter please?

Cheers,

How is the cable split at the moment? Is it split using a proper box? Or is the cable just split out to the 4 different locations?

Depending on how it's done, you might find you don't need a booster at all, and that just having a proper splitter makes everything work better. Something like this.

If it's using a proper splitter, and a booster is required, then just something like this would be fine…

Screwfix do some that are fine for the job;
