I did a pretty extensive analysis of this antenna including adding
screening for receiving AO-40. The article withh all the details
and measurements is in the proceedings of the 2004 AMSAT Space Symposium.
This antenna was designed for max gain, not space communications, and it has
a very high noise temperature. However, for receiving AO-51, the stock dish
is fine. An initial analysis shows that it should be fine for receiving Eagle
on S-band in most cases also.
