I'd suggest you consider the water tank as a reflector of the type called
Gregorian after James Gregory of England who devised it about 1660, and the

Yes, but what's bugging me is that I'm sure there are BAD distances,
especially up close within 1-2 wavelengths

I don't think you are going to be able to model it to your satisfaction with
