Variable Coaxial Attenuator 0-20dB (75ohm)Overview - Decibel (dB) is a logarithmicunit of measurement that expresses the magnitude of a physical quantity,usually power or intensity. This device will reduce the signal strength between0-20dB to hopefully help you achieve a better signal quality.

It will usually take trial and error towork out what the problem is. An attenuator is usually the cheapest option toestablish what the problem might be.The example below is to guide you through a typical aerial installation,this may vary if the attenuator is not being using with an aerial, however thesame principles apply.If you have installed an aerial and you've done the basics such asmaking sure it is pointing in the right direction and you are sure thatall your contacts are making a good connection then, it may also be worthlooking at houses near to you, look at their aerials, if yours looks to bepointing in a similar direction and is a similar sort of aerial, it may beworth asking them if they have any problems with reception. If their receptionis fine, it is likely that you have made a mistake somewhere when installing.If everything seems to be installed correctly and you are still gettingproblems with reception, buying this attenuator will establish whether yoursignal is too weak or too strong. When installed, if your signal qualitydeteriorates further, then your signal is too.
