Aerial amplifiers can be very useful if your signal reception is not quite up to scratch. They are used to improve the performance of your T.V. or radio equipment. If your T.V. picture is 'grainy' or in the case of Digital Freeview, your picture 'freezes' or is 'pixilated' then this item may solve your problem. Poor FM radio reception causes background 'mush' and possible loss of Stereo reception.

The best place to site the amplifier, is as near to the aerial as possible as this is the point where your signal is strongest. If your aerial or the incoming cable  is in the loft area then this would be an ideal location. If this is not practical then it can be fitted at the T.V. end of your aerial lead. Some amplifiers have more than one output so you can run more than one set from them. You should look at the gain or amplification factor of the amplifier. The higher the gain the more amplification you will receive. The gain is measured in dB.

Aerial amplifiers are ideal for running more than one set from your aerial. If you fit an aerial splitter to your aerial downlead you are in effect cutting your signal in half thus reducing it by 50%. An amplifier insures that your signal output is at maximum on all output sockets with no signal being lost. When used in this way aerial amplifiers are sometimes called aerial distribution amplifiers.

If your signal is very poor then this is probably not the item for your needs. In very poor signal areas, mast head amplifiers are usually fitted. These are amplifiers which are fitted to the aerial mast and are powered by a power supply unit. The power supply units are usually sited in loft areas or at the T.V. These items are usually installed by aerial installers and cost in the region of £150. You may also find that replacing the co-ax cable with a quality low loss type such as RG6 (satellite cable) will also help. It is also a good idea to look at your aerial and make sure it is pointing in the same direction as your neighbours. If it has moved and is pointing in the wrong direction then realignment is probably all that is required. If your signal varies in strength and is more noticeable on windy days, it is likely that you have a tree in front of the aerial, blocking the signal as the branches move in the wind. If the tree is not an evergreen then the condition may improve in the Autumn when the leaves fall. The problem may be that the tree is in another garden or has a preservation order on it, in this case getting the saw out is not an option! Moving the aerial to another position, if possible, may solve this problem. If not, have you thought about moving to a tree house? ........If you can't beat them, join them!
