Boosting Signal?


Standard Member
Hi all,

I live in Swansea and according to information on ukfree.tv the Kilvey transmitter which is the closest to me broadcasts several channels such as Dave, Sky 3, E4+1, etc... (all the best ones!) at a really low power. This obviously means that I can't pickup these channels with any kind of consistency.

I was wondering if there is any way I can 'boost' the signal after picking it up on my ariel so that I can view them properly? Am I naive in looking for a 'signal booster' or some such convenient device heh?

Any help would be appreciated! Thanks!

Signal boosters (amplifiers) are available from most electrical type shops. Argos sell them, so you can try one and take it back if it doesn't work. Whether one will help depends on the exact signal level and a few other factors at you location.

Take a look at this information from Satcure:

What type of aerial are you using now? Is is indoors set-top or outside?
Using a central Swansea postcode as an example, Wolfbane gives the following result


As GaryB said there are too many (unknown) factors to say if a booster would work or not

More info on aerial being used here

As "...18 element wideband ariel (didn't see the point of going larger since I'm really close). The new ariel is pointing directly at the transmitter..."
is being used I can't see any obvious reason to use a booster. Is there too much signal I wonder.

Sorry for not providing more information.

I am using an 18 element wideband rooftop ariel as I mentioned in that post.

What do you mean by 'too much signal'? Is that even possible? :confused:

Yes, there was a post on here recently with exactly that problem of a signal which was too high


and also

"Too much signal? In some cases, if you're fairly close to your TV transmitter, you may be getting too much signal, and could be overloading your Freeview receiver. If this is the case, you need an Aerial attenuator from Maplin. This plugs into the aerial socket and reduces the signal."
