If he knew the TOA could he not ascertain the height of the reflecting layer
using your "hop distance" program:.
I suspect that your program on the same subject has a similar use so perhaps
you could answer your own question.
With my antenna having a TOA of 10 degrees I could work out backwards a
whole mine of information all based around your program, assuming your input
data is correct. Grin

Sure, just rent a helicopter and make field strength
measurements.

What use would he make of take-off angle if he ever gets to know it.
