SLx Gold 1 Way Plug-Through TV Signal Booster is designed to boost
Digital TV or Digital Radio signals to a TV or DAB tuner.The gain is
adjustable (0-14dB) allowing you to get the correct amount of gain for
your particular situation. A lot of people do not realise this, but too
much gain is as bad as too little.
Unlike a lot of other plug in aerial amplifiers and TV signal boosters, the SLx Gold 1 Way is Plug-Through (or as it says on the packaging "Plug-Thru"). This means that you do not lose the use of the socket by plugging in the signal booster. There is a 13Amp plug socket as a part of the amplifier itself.
Apart from all the normal things you get from a TV signal booster the SLx Gold 1 Way Plug-Through Booster also has a built TETRA Filter. This filter helps to eliminate interference caused by emergency service TETRA Radio systems.
