Transmitter Höhbeck

The transmitter Höhbeck (internal designation: radio transmission point Gartow ) is a transmission system of the Deutsche Telekom AG for directional radio as well as for the distribution of VHF programs. It is located on the Höhbeck elevation, up to 76 meters above sea level, in the Lüchow-Dannenberg district . A 344 meter high guyed steel framework mast is used as the antenna carrier and a 44 meter high reinforced concrete tower is used as the directional radio tower . The individual parts of the large mast were manufactured, galvanized and coated with paint in a Geesthacht shipyard . These components were then mounted on concrete foundations on the Höhbeck.

Until July 1, 2008, analog television was also broadcast from the transmitter. The 324 meter high Gartow 1 radio mast used for this purpose was blown up on August 20, 2009 .

Gartow 1

The 324 m high Gartow 1 radio mast was built in 1963 with a stable construction and was partly guyed to double guys . It was used to implement an over-the-horizon radio link to West Berlin and had several square grid structures in the upper part that represented the radio antennas. The opposite station was the Berlin-Schäferberg telecommunications tower . With directional antennas and high transmitter powers was diffraction effect of radio waves used. From here the ZDF was broadcast analogue on channel 21 and the Deutschlandfunk on 102.2 MHz with 94 kW. The television stations for rbb television and NDR television were shut down at the end of 2006 and early 2007 with the introduction of DVB-T . The cessation of the ZDF broadcast and thus the entire television broadcasting operations from the Höhbeck location was completed on July 1, 2008 with the introduction of DVB-T in northern Saxony-Anhalt .

Demolition

The steel truss mast that had become inoperative was blown up on August 20, 2009. Three kilograms of Semtex Razor 40 were used as the explosive . The explosive consisted of 16 cutting charges attached to eight guy flaps. The guys, with which the mast was guyed in a north-easterly direction, were separated at the guy foundation. The radio mast was still guyed to the northwest and south and therefore fell in a south-westerly direction over the road between Brünkendorf and the Schwedenschanze . A fall direction of 244 degrees was planned.

Originally a demolition was planned for New Year's Eve 2008/2009. However, the radio mast contained a high proportion of asbestos-containing substances that had to be removed beforehand. The removal lasted until spring 2009. This resulted in a further delay because the breeding and setting time from March 1 to July 15, 2009 in the Lower Saxony Elbe Valley Biosphere Reserve , in which the transmitter is located, also had to be observed.

Detail of the top

The 344 m high Gartow 2 radio mast was built from 1977 to 1979. From May 1980, a (quasi) line of sight for an interference-free radio link between West Berlin and West Germany was possible for the first time from May 1980 on the mast of the Berlin-Frohnau radio relay system, which was erected at the same time and structurally . Up until the commissioning of this system, this was only possible across the territory of the former GDR with the help of the complex technology of over-horizon radio relay, which required high transmission power and sensitive receiving systems. Since this mast carried the directional radio antennas on top, it was built in a particularly heavy design. At four heights of 60 m, 132 m, 216 m and 312 m, it is partially guyed to double guys and contains several closed operating rooms and an elevator for six people.

This mast has also been equipped with a wind measuring system since 1989. At a distance of 18 meters, the wind speeds and directions are measured with anemometers and wind direction sensors. In addition, strain gauges are attached to the corner posts of the mast and the connections of the guys to measure the mast stress due to wind. The Gartow measuring system is operated by the Institute for Steel Construction at the Technical University of Braunschweig .

The operating room at a height of 325 meters represents the highest closed space above the ground in a building in the EU area.

Radio amateurs also operate a relay station for amateur radio television here . In addition, it carries transmission antennas for broadcasting the FM program Deutschlandfunk (DLF) on 102.2 MHz with 94 kW ERP. A future use for broadcasting DVB-T programs is in principle possible after installing a corresponding antenna on the tip, but was not carried out for reasons of cost.
