Another question (pardon my ignorance)


Is it a given that the TOA that the antenna is "putting out" should be
the same as the incoming angle? Is their no change over time?

An antenna radiates at all elevation angles. It does not "put out" at
any single angle. Likewise, it receives signals from all elevation
angles, not just a single one.
