Success Story - China

"Itelco consolidates its market share with a new successful installation"

by Andrea Severino and Giuseppe Maniconi

In a concerted effort with the local TV station of Foshan near the capital city of Guangdong province in China, Itelco has successfully installed its most sophisticated system yet after similar successes in Shantou and Jinan. Installed on the 230-meter steel tower the complete system included a 20+20 KW passive reserve IOT UHF transmitter system, a microwave link to the broadcast studio and antenna system from COEL. A sophisticated monitoring and test system was also supplied to set and maintain the broadcast signal at the specified levels. In case of failure of one of the two transmitters the automatic switch-over system engages the stand-by transmitter within a few seconds to continue regular broadcasting operations.

The new system included some of the latest developments for the now proven Itelco IOT technology. Such developments are aired at guaranteeing the highest reliability to the customer while improving intermodulation noise to lower levels by use of Itelco newly designed IOT cavity. Installation of such sophisticated system is critical in a country like China where dust levels and voltage mains variations are higher than average. For this purpose 2 Itelco specialists and a team of engineers from Foshan TV station and from the Municipal Bureau worked together for almost a month to guarantee proper operation and performance of the transmitter system while improving the Transmitter room environmental conditions.

After a 3-day acceptance session the signal was measured to be strong and clear within 70 Km from the tower and the first programs went on the air on December 8th as planned. The representative from the newly established Itelco Beijing office, Mr. Liu Dameng, helped throughout the effort and is always ready to interface with the customer for all needed assistance.
