![]() "christofire" wrote in message ... snip The antenna I'm trying to remember was receive only and was less than 6 feet high. It had a shape that sort of resembled a squat wire basket. Sal Sal, There's a directory of antennas used at one time or another by the US Navy at http://www.combatindex.com/hardware/...nsor_main.html. Could it be the AS-2231? No, that's called a sleeve, I think, but I moused over the MIL nomenclatures and looked at each picture. The antenna I was thinking of is the AS-2866/SRR. I am surprised to see in the write-up that it's only 24 inches tall. I thought twice that. I used that website many times when I was working (prior to June, 2007) and was wishing I had saved the link on my home computer. Now I have it again :-))) I was aware that the discage in at least one of its incarnations had two separate feed lines, and the combination of two antennas in one 'package' gives rise to its particular shape. However, it has always intrigued me that a single element of similar shape has been used since the early 50s by the British Navy in the AJE/UK-SRA-102: http://middle-watch.com/communications.htm and http://rnmuseumradarandcommunication...org.uk/AJE.pdf. This could be a coincidence or it could be that F. A. Kitchen, the designer of the AJE, had been influenced by having previously seen a discage (his paper about development of the AJE doesn't really explain where the shape comes from). So I wonder when the AS-2802 'discage' came into use? I think it was removed from USS Dubuque (LPD-7) during the ship's overhaul in 1982/83. I was there but the memory gets a little hazy about such details. If that recollection is correct, it predates the 1980s. |
