Ismaning radio transmitter

From this point of feeding, several wires ran to the arms on the tower top and to fastening spots at a height of 80 metres.

At this height a differential transformer was installed in a small housing inside the tower; its task was to prevent the drain of the radiated high frequency over the feeder.

Restrictions of the waveplan of Geneva required a minimum of radiation in direction Northeast, in order to reduce interferences of the transmitter Saint Petersburg, Russia, on the same frequency, if transmission power is 600 kilowatts at night.

As back-up aerial a 105-metre-high (344 ft), guyed steel framework mast was built in 1947[3][4] close to the transmitter building.

This mast, which was originally used for transmitting the program of AFN was until 1969 126 metres high and carried from 1958 to 1969 aerials for FM transmissions.

Restriction by the waveplan of Copenhagen had the result, that the mediumwave transmitter of the Bavarian Broadcasting Company had to work with directional radiation with minimum toward Northeast after 1951 at nighttime.

As aerials for shortwave transmissions of the Bavarian broadcasting company there are a dipole aerial, built in 1976, which hangs on two guyed steelframework masts with a height of 35 metres and a winkle dipole which hangs on three guyed steel framework masts with a height of 55 metres.

For FM broadcasting transmission, there is a silvery grey guyed steel framework mast with dipol arrays on its top near the station building.

[12][13] The Voice of America ran until 1994 near the station of the Bavarian Broadcasting company a large shortwave transmission facility, which has nowadays has been scrapped The medium wave transmission facility of the Voice of America and Radio Free Europe/Radio Liberty operated by the International Broadcasting Bureau was shut down in March 2005.
