[amsat-bb] Re: The Eagle has died.

[John B. Stephensen]

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.

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.
