TEM was established in 1977 by a team of specialists in radio communication and broadcasting. In 1978 TEM begun manufacturing FM transmitters with an output power of 20W to 10kW. New 40 kW FM transmitter is actually available. The production of TV transmitters dates back to 1979, while the first microwave links were installed in 1981 and today more than 9.500 microwave systems are installed worldwide. Huge effort has been given to the development of new digital technologies, mainly in the last two years. Today TEM manufactures the following product lines :
