I really hope this is not another trick question, if not, better get a new antenna, radio, and/or coax - seriously.
A 70 degree pass of the Fox-es and a clear view, their strong signal be received with a random wire.
On such a high pass, normally get 4of9 bars with a rubber duck and 8of9 bars with a 2 el yagi !

suggested the most obvious one...
most of our satellites have, after all, INVERTING transponders!

When the satellite is directly overhead with a vertical antenna that might
be tough to contact. Perhaps pointing the antenna at the ground is causing
the signal to bounce and reflect.

Are the elements installed on the boom backwards? :0
Shortest element closest to the satellite.
What antenna problem causes a null off the tip of the boom?
