31.3.2 Olympic Tower Transmitter, Munich

The Munich Olympic Tower has originally been built in 1968 as telecom-
munications tower. Since April 2005, it has at its top the DVB-T transmit-
ting antennas which, together with the Mt. Wendelstein transmitter, form
the DVB-T single-frequency network Southern Bavaria since May 30th,
2005. From here, too, a total of 6 channels are broadcast in single fre-
quency completely synchronized with the Mt. Wendelstein transmitter.
The output power of the DVB-T-transmitters is approximately twice as
high as that of the transmitters on the Wendelstein mountain. It is about 10
kW per channel in the UHF band. In contrast to the Mt. Wendelstein
transmitter, where the main pattern of the antenna points to the North, the
Olympic Tower has an omni-directional pattern. The ERP is about 100 kW
in the UHF band from the Olympic Tower.
