Talk:Circularly disposed antenna array

What obsoleted the Wullenweber?

The article reports that these antenna arrays have pretty much all been abandoned. What technology replaced them? We don't say. --Gnuish (talk) 01:06, 27 March 2011 (UTC)

The German wikipedia article about the Gablingen facility explains this: https://de.wikipedia.org/wiki/Abh%C3%B6ranlage_Gablingen Triangulation is not possible with just one active device. Modern satellite technology is more effective than conventional antennas. US-military has abondoned Gablingen, the array itself is in a bad state, the bunker is not usable any more. Due to the fact that the military still make a big secret out of the facility and even remove map entries (not Google earth aerials, just descriptive entries such maps.google) local people spread lots of stories about the big underground facility which as far as I know is only small and by now without any military importance since NSA and military found a new home in other facilities such as Bad Aibling (Bavaria). At the moment, there is a strong public demand for means against espionage in Germany and the BND is starting to make its facilities official. Concerning the wullenweber device: I hope that the Gablingen facility will be opened for public before the antenna - which is an important relic of technology - will be destroyed due to bad maintenance. --lechspitz 19:55, 31 May 2015 (CEST)

"Skisby"

They article states: The first Wullenwever was built during the war at Skisby (in German: Hjörring), Denmark.

There is no place called "Skisby". There is however, a Skibsby, which is a village just outside the city of Hjørring (which the Germans would have spelled "Hjörring"). However this is almost 20 km west of the coordinates given in the article (correcting 10°20'04" E to 10°00'04" E does produce a location close to Skibsby, though). –Henning Makholm (talk) 20:01, 29 November 2011 (UTC)

Lots of claims and facts, but no citations...

This article is rich with claims and facts, but totally lacking in citations. What are the secondary or primary sources for the various claims and facts? Without citations I have no way to verify the reliability of information presented.

For example, the article says: "After the Hanza array was decommissioned in 2006, the Canadians now operate the last two FRD-10 arrays in existence." What is the reliable source for this claim? I doubt that the statement is entirely true, but truth isn't the issue. The issue is whether or not this claim is from a verifiable and reliable source, as defined by WP:SOURCE.

Skibsby

Skibsby, north-east of the city of Hjørring (in German: Hjörring), Denmark - the coordinates given - 57°28′39″ N 10°20′04″ E are obviously wrong, this is a place further east, rather in Fredrikshavn. --Reinhard Kraasch (talk) 00:01, 18 May 2020 (UTC)

Yeah, the coordinates given clearly don't make sense, and are unsourced to boot. A bit of googling found me a (similarly unsourced, to be sure) claim of 57°29'10"N 10°00'38"E, which (a) is actually near Skibsby; (b) points to a plot of land that according to Google Maps is used by the Danish Defense Intelligence Service, which supports an inference that the Germans might have built a radio installation there during WWII; (c) the Google Maps aerophoto seems to show some ghostly circular traces in the vegetation of about the right diameter.

I'll change the coordinates accordingly; at least it looks unlikely that will be _more_ wrong than what is there currently. –Henning Makholm (talk) 21:28, 4 October 2024 (UTC)

Hmm, dewiki gives (just as unsourced) the coordinates as 57°29'04"N 10°01'11"E, which is about 600 m east of the coordinates I just edited in. I think I like mine a bit more; at least they point to land within the current intelligence facility. –Henning Makholm (talk) 21:40, 4 October 2024 (UTC)

Plath GmbH

C. Plath was founded 1862, so Maximilian Wächtler cannot have founded it. Maybe he re-founded it after WWII. --Reinhard Kraasch (talk) 00:10, 18 May 2020 (UTC)
