[QUOTE="s-band, post: 1067649, member: 407744"] I had a quick look at 25E but using the S band front end and feed on a 1.2m. Both feed and LNA have drooped a bit by 1500MHz but Alphasat is there. The 2nd plot looks a bit like aero but it doesn't tie up with Jonti's site. However, that could be old info. [ATTACH]123083[/ATTACH][ATTACH]123084[/ATTACH] Curiously I found another big L band thing at about 45E. At L band the direction finding ability is poor though but it is probably within 2-3 degrees It's much stronger but is mainly pulsed signals. See plot where yellow is real time and green is max held. Any ideas [USER=187415]@hvdh[/USER] ? [ATTACH]123085[/ATTACH] I'm not sure you'll get enough s/n from a QFH but anything is worth a try. Find something using your helical first though. e-mail if you have questions. <edit> I just found these in the archive from May 2016 on 25E: [ATTACH]123088[/ATTACH][ATTACH]123088[/ATTACH][ATTACH]123089[/ATTACH] [/QUOTE]
