Electrical Interference to FM Broadcast Radio

Almost all reception difficulties are caused by faults or deficiencies in the radio or antenna installation. This can be checked by following the procedure below:

Substitute another radio for the affected one. If the second radio is not affected, the problem is most likely in the first radio. If it is affected check your antenna.

For the best possible reception your antenna should be mounted outside and look similar to a TV antenna. Sometimes the TV antenna is used for both the TV and FM radio. If this is the case, remove the TV connection, leaving only the direct cable between the antenna and radio.

Check that your antenna is suitable for FM radio (a technician will be able to advise you about this).
 

Three Element FM aerial - pictured below -   This aerial pulls in signals from local transmitters and ones further a field.  Example:  if you have got noisy or hissing radio stations that keep going into mono this aerial will bring the best stereo reception.  It is also directional and can be aimed at a certain transmitter but will still give you the local transmitters as well.
