The transmitter is located about 660 m east of the Königsstuhl rock formation , the highest point of which corresponds to the mountain summit, next to a 673.5 m high point. A former US Army transmitter is located about 350 m west of its transmission tower , and the Ludwigsturm observation tower is 210 m east .
overview
The transmitter Donnersberg serves as the basic network transmitter for VHF radio and DAB + as well as television (DVB-T) and supplies large parts of the Palatinate without the southern Palatinate , the Nahe region, Rheinhessen , the Rhine-Neckar region and the Rhine Valley between Speyer / Bruchsal and Wiesbaden .
A 1961 serves as an antenna carrier reinforced concrete construction erected television tower , the at 670.52 m stands height. It was originally 207.04 m high. After the conversion to DVB-T, its height has been only 204.82 m since October 12, 2007. Until this changeover, the tower also served as a mother transmitter for a large number of unmanned TV fill transmitters.
The tower, which is not accessible to the public, has become a landmark of the Donnersberg that can be seen from afar.
After the Kettrichhof transmitter, the tower is the second tallest building in the Palatinate. In the immediate vicinity, after the Second World War (1939-1945), the largest radio station in Western Europe was built for the US Army , which was of paramount importance for the connection to the USA , especially during the Cold War .

DVB-T (2007-2018)
On December 4, 2007, the transmission tower was switched from analog broadcasting to DVB-T . For this purpose, the previous television antenna was replaced by a DVB-T compatible antenna on October 12, 2007. Today's digital broadcasts running in single-frequency operation (Single Frequency Network) with other transmitter sites.

In most cases, DVB-T reception from the Rhine-Main area is also possible ( DVB-T Rhine-Main ). From there come the private broadcasting groups RTL Group and ProSiebenSat.1 Media as well as a mixed private multiplex that also contains Tele 5 . A roof antenna aligned vertically at the Großer Feldberg im Taunus location is the best solution in this regard. Indoor or outdoor antenna reception may also be possible in favorable locations. When using roof antennas, it should be noted that both band III VHF and band IV / V UHF are broadcast. This means that either a combination antenna Band III VHF / Band IV / V UHF or two different antennas suitable for the respective areas can be mounted in vertical polarization on the antenna mast. After the relocation of the DVB-T multiplex ARD regional hr Rhein-Main, which is currently broadcasting in Band III VHF, to Band IV / V UHF by July 2009, DAB radio reception is then also possible via Band III VHF with the antenna set.
On December 4, 2007, the E37 channel, which was formerly used on the Donnersberg, went to Hessischer Rundfunk, which thus covers the Rhine-Main area and southern Hesse with the ARD national hr multiplex (Das Erste (hr), hr-Fernsehen, arte / EinsFestival ) digitally supplied. In return, the SWR received the E57 channel, which was previously in operation in the Rhine-Main area at the Großer Feldberg (Taunus), Europaturm (Frankfurt am Main) and on the Hohen Wurzel (Taunus) sites with this same multiplex.
DVB-T2 HD (from 2018)
On November 28, 2018, the switch to DVB-T2 HD will be in regular operation together with the regions of Eifel (Eifel transmitter ), Mosel-Saar ( Trier-Petrisberg telecommunications tower ) and the Palatinate with the Donnersberg and Kaiserslautern telecommunications tower , with three bouquet from ARD , ZDF and SWR.

Other transmission systems
Because of its exposed location, the Donnersberg is also used by other transmission system operators. The US Army built the largest radio station in Western Europe and a smaller one there after the Second World War . These were also used by the US soldiers in Germany to broadcast the moon landing in 1969 .
The smaller of the two plants was given up in the 1990s and went into civil use. Today the masts used as radio relay stations of Pfalzwerke . The large radio station was given up in October 2011, the site came to the Federal Agency for Real Estate Tasks . At the beginning of 2015, following a public tender, the Saarland- based telecommunications company Inexio KGaA acquired the station from the Federal Agency for Real Estate Tasks.
