[QUOTE="cazhh, post: 888728, member: 391121"] I finally have measurements from the first sidelobe just 160km to the east. (Thanks to lnb123 @forum.digitalfernsehen.de) The result is pretty amazing and shows how the east/west wobble works. [url=http://abload.de/image.php?img=allweek-140528-lnb123imsuh.jpg][img]http://abload.de/thumb/allweek-140528-lnb123imsuh.jpg[/img][/url] in the top graph you see my measurements here on the east end of the mainlobe. The bottom one shows the SNR measured in Rostock. Astra 2F is in blue/pink, Astra 2E in red/green. As you can see 2F is in Rostock already nearly saturated. That means the center of the sidelobe is nearer to Rostock, while 2E still shows the whole snr variation. This can be seen better when i transform the rostock values and merge them with mine. (the Rostock value is multiplicated with 18.74 and inverted) the two 2e graphs almost merge. [url=http://abload.de/image.php?img=rostock-elmshornc3jhm.jpg][img]http://abload.de/thumb/rostock-elmshornc3jhm.jpg[/img][/url] 2F is different [url=http://abload.de/image.php?img=elmshorn-rostock-2fgyssg.jpg][img]http://abload.de/thumb/elmshorn-rostock-2fgyssg.jpg[/img][/url] I didn't expect that 2e would be that symmetrical.
