use
The transmitter of the Deutsche Funkturm GmbH (DFMG) bears the internal name Münster 42 . On the tower there are, among other things, several VHF transmission systems, radio converters for BOS radio and base stations for mobile radio applications .
Since June 12, 2007, the Münster telecommunications tower has been broadcasting digital television in DVB-T standard, and since April 25, 2018 in DVB-T2 HD with the complementary private programming offered by Freenet TV . For this purpose, on April 27, 2007, a coupling for a new antenna construction was attached to the top of the tower by helicopter. With the new antenna, which was installed on May 15, 2007, the tower increased from its original height of 222.5 m to 229.5 m.
In addition, various radio links were maintained for telephony services, but these were increasingly being replaced by fiber optic connections . There are currently only three important radio links from Münster to Bielefeld , Schwerte and Haltern am See . The radio tower is also home to the automatically operating relay radio stations DBØHH and DBØOVM of the amateur radio association VFDB-Z14.
