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.
