Here are some ANITA/PUEO pictures that I received from Christian Mike that might be helpful.  I include his descriptions as well.

The one with the black crates in the background is the  ANITA 1 and ANITA 2 form factor and the one in the anechoic chamber is the ANITA 3 and ANITA 4 form factor. I dimensioned out an ANITA 3/4 antenna, in CAD space, to give you a better idea of the ridge profile. The ANITA 1/2 CAD models we have, I found, are inaccurate.

Attached are images of the PUEO antenna array geometry. One image annotates the approximate locations of the Vpol feed with the top antenna feed as the origin.
