Air traffic obstacle
Encyclopedia
An Air traffic obstacle is a tall structure which can endanger air traffic. Air traffic obstacles have to be marked in most cases with red and white colored markings and with aircraft warning lights
at night. On larger structures blinking lights are required. An example of an air traffic obstacle is the air traffic control tower.
In the past lamps similar to those used on lighthouses were sometimes used. There are still such lamps on Fernsehturm Stuttgart
in Stuttgart, Germany. A fainter rotating light is on Blosenbergturm
, Beromünster
, Switzerland.
A special method of marking was used at the mast of Deutschlandsender Herzberg/Elster
in 1939. On small poles near the mast multiple rotating skybeamers were mounted which illuminated the lens-like structure on the top. Because of this no electrical installation was required on this mast.
Aircraft warning lights
Aircraft warning lights are high-intensity lighting devices that are attached to tall structures and are used as collision avoidance measures. Such devices make structures more visible to passing aircraft and are usually used at night, although they may be used during the day as well...

Deutschlandsender Herzberg/Elster
The Deutschlandsender Herzberg/Elster was a 500 kilowatt long-wave transmitter at Herzberg/Elster, which was in service from 1939 to 1945. It used a 337 metre high guyed steel lattice mast of triangular cross section. This was used as a mast radiator and was therefore mounted on a 0.75 metre high...
