John,

Your Eggbeater is looking UP for satellites.
Hearing below 15-20 degrees is tough.
It is great for overhead passes!
A preamp would help, but your radiation angle is the problem.
I simple 5/8 wave vertical is good for lower angles, and for higher angles 
on close passes. A 1/4 wave or a loop antenna with a preamp would work ok. 
Keep in mind that noise is vertically polorized.

73, Scott
