1 Multi Carrier (Mauritius) Ltd Television Reception Guide 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 better television reception: Locating the relay stations Frequency Bands for Terrestrial Television Broadcasting Choice of TV Antenna Antenna placement and positioning Cabling and distribution Notes 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. Table A : Locating the relay station covering your area Station Intended coverage areas Centre Malherbes Curepipe, Castel, Phoenix, Quatre-Bornes, Belle Rose, Rose-Hill, Beau-Bassin, Reduit, Moka, St- Pierre, Q-Militaire, Vacoas, Floreal, Henrietta, La Marie, Forest-Side, Nouvelle France, Rose-Belle, Plaine-Magnien, Mahebourg and their nearby regions.

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. Table B shows the range of frequencies used for television broadcasting in Mauritius and Rodrigues. Page 2 of 5

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. Page 4 of 5

5 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. Page 5 of 5
