|On the outskirts of the town at the edge of the camping site is a radio guidance bunker. The bunker is 130 meters above the sea. The system used here was the second generation of radio guidance called Y-Gerat. For an explanation of this system consult the pages on Fort Allemand. The aerial was mounted on the roof of the bunker and was rotated to its position on a rail, the supports of this rai...||01/15/2010||318|
|This is the horn antenna of the Bell Laboratories. In 1964 Robert Woodrow Wilson and Arno Penzias accidentally discovered with this antenna the Cosmic microwave background radiation, considered as the best evidence for the Big Bang theory.|
In 1978, Wilson and Penzias received the Nobel Price for their discovery.

|The Star Tower is a 956 foot (291.4 m) high transmitting tower for TV and FM in Cincinnati, Ohio at 39°12′01″N, 84°31′22″W. It was built for WSTR-TV, then known as "Star 64", which still broadcasts from the tower a non-directional antenna for its analog signal, and a directional antenna pointing northwest for digital. It was built in 1991 using a helicopter. Similar stru...||04/15/2007||497|
|Erika was a late development in radio guidance, and came too late to have much effect on the German’s war effort. They had started with Knickebein, then progressed to X-Gerat and Y-Gerat, all of which were far superior to anything the Allies had at that time. The only problem with this system was the large number of bunkers needed which allowed the planes of the RAF to spot the installations. E...||01/15/2010||427|
|The Effelsberg telescope is one of the World's largest fully steerable instruments. This extreme-precision antenna is used exclusively for research in radio astronomy, both as a stand-alone instrument as well as for Very Long Baseline Interferometry (VLBI) experiments.|
