Loops Aerial Coaxial Cable Variable Attenuator

• 0-20dB range.

Variable Coaxial Attenuator 0-20dB (75ohm) Compatible with: Digital (freeview) and analogue signal signals Satellite signals Cable TV Technical Details: VSWR - Voltage standing wave ratio is kept low to maintain signal integrity Variable Attenuator - This attenuator can be adjusted from 0 - 20db Frequency Range - 5 - 1000Mhz Resistance - 75 ohm rated High quality metal surround construction If you experience break-up on some or all of your channels whilst trying to tune in your TV, it could be that your signal is too strong or too weak. It will usually take trial and error to work out what the problem is. An attenuator is usually the cheapest option to establish what the problem might be. If you have installed an aerial and you've done the basics such as making sure it is pointing in the right direction and you are sure that all your contacts are making a good connection, and you are still getting problems with reception, buying this attenuator will establish whether your signal is too weak or too strong. When installed, if your signal quality deteriorates further, then your signal is too weak, if the signal goes better you should leave this attenuator installed and set the variable dial to the point that gives the best signal. One other way to reduce your signal strength (to check whether you need an attenuator) is to put your signal through an extremely long length of cable. Good quality coaxial cable loses about 0.18db/metre, therefore a cable run of 40 metres would lose about 7.2db. How to use: The attenuator should be positioned between your aerial (or other device) and splitter (in your loft), if you don't have a splitter then it should be positioned between your aerial and TV.
