The sidelobes from a good antenna are only 20 dB down and published studies show up to 40 dB of excess noise. Eagle will also have a lower elevation than AO-40.

Hello For me AO-40 was an "easy sat". A 30 inch primestar, helix feed, and a
3731 d/c. Only an occasional "click" from whatever. If we are looking at the sky with a dish, how does the higher noise floor and qrm from the ground affect our reception. I admit I am not quite understanding something.

Mode U/S with AO-40 was a real pleasure to work, with excellent signals
once
the receiving set-up had been optimized (1.2 m solid dish and a good
DB6NT
LNA). Living here in high density WiFi area, cordless phones, wireless CCTV
and
all kind of 2.4 Ghz junk ! I could regularly hear the noise floor of the S band transponder and
contact
very low power stations. 73's Eric EA5GIY
