Is there any reliable way to tell what the "real" height of a yagi is
that's on top of a building? In other words, electrically how high the
antenna thinks it is. Is there a formula to calculate this if one knows
all of the critical information (dimensions of the building, antenna
height above building, etc.) and assuming that the building is a 3D
square or rectangle? Are there any rules of thumb for this or is
modeling the only way?
