The video of the array begins at about half way through the video. It appears to be hundreds of phased verticals in front of a circular reflecting screen. Each element of the array appears to be a br
That is a Wullenwber (or Wullenwever) array. See: http://en.wikipedia.org/wiki/Wullenweber It would have probably made one heck of an 80/160 meter receive antenna <G>. The video appears to be one of
Frank: I think the antenna in the video is a former Soviet Union "Cold War" version of a German Wullenweber also known as a Circularly Disposed Antenna Array (CDAA) http://en.wikipedia.org/wiki/Wulle
Back in the day, we (US Army) had a 1/2 mile diameter, 100 feet high wire array located in south Florida. I routinely copied Russian aircraft taxing on the runways in Russia using cw. This looks some
Yep - one of 'dem can be seen down in San Diego, at the southern tip of Cornado and at the northern tip of Imperial Beach - the "site" is, if I understand it correctly, now owned and operated by the

The Soviet Krug array was a much smaller than the array in the video, nearly identical to the World War II German Wullenweber array. The Krug construction techniques were far different and much less
I started hearing the Woodpecker on 20M at NSGA Bremerhaven, on the North Sea coast, in the late 1960's. It would completely peg the S Meter and wipe out every signal on the band. Even the Italian st
I wish I had taken Pics of our Rhombic Antenna farm at Camp Darby near Livorno (Leghorn) Italia At the Xmtr site we had Rhombic ant. in every direction 360 ft on a side wit three wires on each leg th
Since some of these large antenna sites are no longer used it could be an ideal location for a SRD receiver feed (for 160 meters only) and with sufficient delay during contests to avoid their misuse,
Herb: If any organization or individual is fortunate enough to gain access to a CDAA there is no reason to limit use of SDR to 160 meters, any band 160 - 10 would benefit. 73, Jack Since some of thes
Jack, As the all band demand would increase the load from a 100 users to thousands, I guess it would be up to the system capacity and if the antennas are capable of the bandwidth requirement at one g
Arrrrg, Herb you have stumbled on to the idea we have joked about here for some time. A pair of 8 element RX arrays for diversity receive served up by subscription on the internet. Located on top the
That would be great Lee but one system won't be enough, you will need to put up any number of systems so subscribers can be assured what is spotted can be heard in their area... Go for it... 73, Jack
I just turned my webcam around and snapped a pix of the proposed array location. How can I resist that low take off angle on 160? Dreams, Ahhhhh. "http://www.k7tjr.com/culver_cam.htm" Lee K7TJR That
. That was the birth of EME, not a resurgance. Sam, W1FZJ, made the first EME contact just a few years before moving from MA to PR. I was one of his antenna "apes" in MA as his favorite saying was "i
W1BU was the club call for the Rhododendron Swamp VHF Society in Medfield, MA and never left there until it expired and was reissued years later. Sams son Pat, W1HIV, still lives there. Carl KM1H ___
There was also one of these at the University of Illinois that was decommissioned in the early 80s. I've seen this thing up close and there were even rumors of some of the W9YH club members hooking a
Here's a Wullenweber that is intact and I believe functional although not used like it was. It's coordinates are 54.028911,-132.065256 and it is quite visible in Google Maps. Of course it belongs to
