The Telecommunication Tower Koblenz (also Telecommunication Tower Kühkopf or Koblenz 10 ) stands in the city forest of Koblenz on the summit of the Kühkopf . The telecommunications tower is the second tallest structure in the Hunsrück after the SWR station in Koblenz and the third tallest in Rhineland-Palatinate .
history
The plans in the early 1970s compared three different types for the Koblenz telecommunications tower: a telecommunications tower for purely telecommunications use, a telecommunications tower with a viewing platform and one with an additional restaurant. The different designs were estimated at 13.247 million, 15.268 million and 24.601 million marks , respectively . The Federal Post Office decided against the additional costs that arise from the viewing platform and the restaurant, as no cost bearer could be found. The need for an observation tower so far away from the city center could not be clearly demonstrated. The final preliminary draft was drawn up by May 1972.
The groundbreaking ceremony took place on April 16, 1974. The topping-out ceremony was celebrated on December 13, 1975. The construction costs amounted to 11.5 million DM, with an additional 11 million DM for the installation of the telecommunications technology. The tower, which is owned by the Deutsche Funkturm and in which asbestos residues were removed until 2005 , is not open to the public.
This tower is mainly used to expand the radio link network for telephone and data connections as well as the transmission of television signals between the television studios and the television stations. It is also a broadcasting location for cellular networks and an important feed-in point for cable television . The top of the tower installed in 1985 broadcasts the radio programs RPR1 and bigFM for the Koblenz region. Since 2002 digital radio has been broadcast via the transmitter on the Kühkopf. In telecommunications tower also is amateur radio - Fonierelais DB0ZK ( 2 m and 70 cm) housed. The 2 m band amateur radio relay was modernized in August 2017 so that connections in FM and digital mode C4FM can now also be handled.
On July 14, 2008, a new antenna system was installed on the telecommunications tower, which has been supplying the Koblenz region with DVB-T television signals since August 26, 2008, raising the tower by 5.70 meters.
description
The telecommunications tower , originally 255 meters high from 1974 to 1976 as a vertical cantilever construction , stands out due to its simple shape. The base of the tower is strongly exposed because of the particularly high foundation floor and has four floors inside for lounges and storage rooms. The foundation of the so-called special tower has a diameter of 28 meters with a foundation depth of four meters. In the shaft there is an elevator and a reinforced concrete staircase with 784 steps up to the tower cage .
The relatively wide, 40-meter-diameter, two-story tower pulpit at a height of 150 meters is pierced by a concrete shaft that tapers upwards, making it look like a giant toothpick. The shaft diameter at the base of the head is only 5.6 meters. Steel frameworks, which sit on the lower operating floor by means of train diagonals, serve as a supporting structure for the tower pulpit .
Frequencies and Programs
Analog radio (FM)
The first nationwide private radio station was activated on April 30, 1986 with the start of RPR1 at this location. It followed on December 9, 1991 with RPR Zwei, a second nationwide broadcasting network. However, this program was discontinued in August 2003. Since then, bigFM has been broadcasting on the frequencies of RPR Zwei.

Digital radio (DAB +)
The digital radio ( DAB + ) is broadcast in vertical polarization and in single-frequency mode with other transmitters. The DAB + broadcast standard has been used since November 16, 2011; broadcasting in the DAB broadcast standard on channel 12A has been switched off. On August 29, 2012, the Bundesmuxx was activated on channel 5C with 10 kW ERP transmission power. On December 3, 2015, Block 11A of the SWR moved to its own location in Dieblich-Waldesch .
Digital television (DVB-T)
Since August 26, 2008, the Koblenz telecommunications tower has broadcast digital aerial television ( DVB-T ) with three public multiplex channels for the Koblenz region. The horizontal polarization is maintained, antennas do not have to be rotated. Today's digital broadcasts running in single-frequency operation (Single Frequency Network) with other transmitter sites.
