Broadcasting Options

Galcom offers the following broadcasting options:

Mother Radio Station

The mother radio station is set at a specific frequency and when installed will reach a radius of many miles/kms depending on the terrain, the wattage of the transmitter and the type and height of the antenna. The signal may be AM, FM or SW. Information on topography and geographic location is required to determine specific needs in setting up a new radio station.

Refer to our 10 Basic Steps for setting up a low powered Christian radio station. Low powered broadcasting is typically considered to be 2,000 watts or less. Galcom has even installed stations as low as 100 milliamps of broadcasting power.

Repeater or Translator Broadcasts

Installing antenna

After a mother station is installed, in some cases, a repeater station or translator can be set up to receive the original signal and then retransmit that signal on a new frequency. This allows the broadcast to be transmitted over a much greater distance. If desired, the second frequency can then be received by a second repeater station and again retransmitted on another frequency. This can be repeated a number of times enabling the signal to jump from one station to another in order to reach a much broader audience.

From the mother station, a series of outlying stations can be installed which will pick up the original frequency and then rebroadcast on a new frequency. This could be likened to a pie with a master station in the center and repeater stations with their own frequency out in different directions.

Studio-to-Transmitter Link Systems (STL’s)

An STL System utilizes two towers and two antennas to send the radio signal from a mother station in order to reach greater distances. The first antenna sends the signal from the studio to a second antenna which is usually located on a nearby hill or mountain top. The signal is then re-transmitted from the higher vantage point which allows it to reach a much broader audience.

Satellite Broadcasting

In areas too vast for traditional repeater station links, broadcasts can be uplinked to satellite and downlinked to repeater stations anywhere in the world. The data can then be rebroadcasted at any time of day over traditional FM frequencies.
