Aerial Information
The Radio 3 needs to be connected to an aerial to work. The FM
aerial socket (No.1 on 'Back Panel' page 9) is designed to accept a
75Ω coaxial cable. If a 300Ω twin lead wire is used to connect an
aerial, use a 300-75Ω adapter.
The very best results from the Radio 3 will be obtained when using
a multi-element aerial mounted externally.
An aerial will also be needed for AM reception. This should consist
of a simple single wire of 4 meters long, connected to the tuner's AM
socket (No.3 on 'Back Panel' page 9) and if possible laid horizontally
along its length. Try to avoid metal shelving and experiment for the
best reception.
Distant AM reception can be improved* by using a 'long-wire' aerial,
mounted externally, parallel to the ground. This should be a single
wire, up to 30 meters long.
Further improvements may be made by connecting the earth socket
(No.2 on 'Back Panel' page 9) on the Radio, to earth, via a copper
plated rod driven into the ground. A substitute electrical earth, such
as a cold water pipe may also prove effective.
*Please Note: If you are close to a broadcasting aerial, the
reception of local AM stations may actually be worsened by this
method.
