The Feeder
The amount of energy hitting the antenna is incredibly small even though
there are hundreds, possibly thousands, of separate individual radio waves
hitting it. Getting this small quantity of energy down to the receiver is
one of the most critical - but often most overlooked - aspects of radio
reception.
The picture shows several different types of coaxial cable - each designed for a specific purpose and it is important to use the type of cable specified by the manufacturer of the receiver even though, in many cases, the cables look the same.
When the manufacturer suggests a 'generic' type of cable, seek advice from the cable supplier and go for the best quality within your budget. - And don't forget the connections at each end of the cable! Good quality plugs will pay in the long term.
