@uhoh, I hope this answers your first question.
I sourced the following 2 paragraphs from an NBC article by Jesse Emspak, "Has Mysterious Signal From Space Finally Been Explained?":
Two big issues are that the signal didn't repeat, and it appeared for such a short time. Ehman noted that the Big Ear telescope had two "feed horns," each of which provides a slightly different field of view for a radio telescope.
"We should have seen the source come through twice in about 3 minutes: one response lasting 72 seconds and a second response for 72 seconds following within about a minute and a half," Ehman told Live Science. "We didn't see the second one."
The first para clearly states that the 'Big Ear' had no single field of view. I also tried to search for this in many ways, but with no luck, the telescope has also been disassembled.
For your second question though, it requires some thinking as the 2 'feed horns' of the telescope give slightly different field of views. I don't know the answer to this yet, but I will attempt to find it.
