Aholming transmitter

Aholming transmitter is a facility for formerly broadcasting the Program of Deutschlandfunk on 207 kHz with a power of 500 kW at day and 250 kW at night between Aholming and Ottmaring in Bavaria. It was (finally) shut down in the early Morning hours of January 1, 2015.The Aholming Transmitter, which could be received in most parts of Europe, was built between 1986 and 1988 as a Replacement for the older Erching transmitter. This became necessary as the Nighttime Operation on 207 kHz requires, according to the Geneva Frequency Plan a directional Radiation Pattern for whose Realization a second Mast was required. This Mast could not be built on the site of the former Erching, as it had to be cleared from tall Structures as in its Proximity the new Airport of Munich was under construction.The Aholming Transmitter, which entered into service on January 1, 1989, uses a directional antenna consisting of two grounded masts, which are guyed at three levels 101, 203 and 239 metres above Ground. Over the guy level, which is fixed with the Mast in a Height of 203 metres, the Transmission Power was fed into each Mast.Therefore, from the Top of the helix building close to the mast three conductor ropes run upward to a point of the 203 metre guy level, which is situated 110 metre away from its anchor point of the Mast.Both Masts, which are equipped in 6 levels with flight safety Lamps are nearly of the same height to wavelength ratio as those of Sender Donebach (0.1829). The distance between them is 483 metres.
