Television Reception Guide (download in pdf format)

The following is intended to be an informative guide to terrestrial television reception. It is highly recommended that you contact an antenna professional for the proper installation of a terrestrial TV antenna system.

General guidelines for a better television reception:

Locating the relay stations
Frequency Bands for Terrestrial Television broadcasting
Choice of TV Antenna
Antenna placement and positioning
Cabling and distribution
Note on Digital Terrestrial Television Reception
Maintenance of antenna system installation
Analogue Television Transmission in Mauritius SECAM B/G in the VHF/UHF bands

1. Locating the relay stations

The first step in planning a television antenna installation is to find out the location of the transmitting station intended for your area. MCML has a national network of stations that covers all the populated regions of the island. Television signals, especially UHF signals travel in straight lines and are obstructed by major obstacles in the landscape such as mountains and tall buildings. Table A below is a guide for locating the appropriate relay station covering your region.

2. Frequency Bands for Terrestrial Television broadcasting

The next step is to determine the radio frequency band that is used by your relay station for broadcasting. The band of frequencies used by your station will be an important factor to choose the right type of antenna.

3. Choice of Antenna

Selecting the right type of antenna is an important factor to ensure good quality of television reception. The following factors can influence the choice for an appropriate antenna.

  • Channel frequencies broadcasted by the relay station
  • Signal strength in your area
  • Presence of major obstacles in the path between your antenna and the relay station

4. Antenna placement and positioning

Once the antenna has been chosen, it should be placed in a location where maximum signal strength is obtained.

  • The antenna must be pointed towards the relay station
  • The antenna should be mounted horizontally for all relay stations except for Le Morne & Pte Jerome where the antenna should be mounted vertically.
  • The antenna should be installed clear of obstacles for example buildings, walls, trees, etc. for good reception.
  • Multiple antennas should not be stacked on a single stand-off pole close to each other. Maintain a distance of at least 50 cm between them.

5. Cabling and distribution

A low loss coaxial cable (impedance of 75 ohms) is recommended for distributing the signal to the receiver. For distributing the signal to more than one television set, a splitter may be used, however a distribution amplifier may be required if the received signal is low.

6. Note on Digital Terrestrial Television Reception

Digital terrestrial television eliminates most of the reception problems of analogue broadcast television such as snowy pictures and ghosting. However like all digital systems, if the signal received is near the minimum threshold, you may get frequent interruptions or no reception at all. To ensure a stable reception, make sure that your antenna system receives a good quality signal comfortably above the minimum level as indicated by the set top box.

7. Maintenance of installation

The antenna installation must be inspected from time to time to detect signs of corrosion or damage. Bad weather conditions, like rain and strong winds can decrease the lifetime of the antenna and cabling.
