Transmission Equipment for a Radio Station

The equipment of a radio station can be broadly classified into two categories:

1) Studio Equipment &
2) Transmission Equipment

We have talked about studio equipment in a separate article. Lets list down the transmission equipment here.

A radio station needs 3 major transmission equipment.  These are:

      Receiver
      Transmitter
      Antennae

Additionally you require some support equipments like audio processors, cables connectors, power supply equipment, interface panels and mounting rack.

These 3 transmission equipments are elaborated as follows:

1) Receiver

Receives transmission signals from the studio setup via cables and connectors. Technically speaking the radio set that is fitted into your car is an example of a receiver. So why do we need a receiver in a radio station ?

The receiver lets us monitor the quality of broadcast from within the radio station.

2) Transmitter

The transmitter transmits the radio signal at a given frequency.

The choice of a transmitter is a vital decision for setting up a radio station. The choice depends upon the radius over which you want to relay your programs. A 300+ W transmitter is the minimum recommended for people planning for a commercial radio station. The choice may vary based on your expected geographical coverage area.

3)Antennae

A good antennae is a very crucial part of radio broadcasting and you should settle for nothing but the best that you can afford. You will need to buy for omni directional antennae, the one which broadcasts in all directions as opposed to a directional antennae which is not relevant in context of radio stations. Choosing a good location for high placement of antennae is very vital for unobstructed broadcasting.
