Above bus height at the tower doesn't mean that every section of the sight lines between the tower and each house is above bus height.

I specifically meant when it comes to mounting it on the office/house endpoint. Everything else in between should have another flexibility when it comes to choosing the location.

Yes, both ends the tower and endpoint can be mounted higher than a bus, but because most building are single story, they can't be mounted that much higher.

So a small increases in elevation in an area between the 2 points means that the LOS can still be crossed by a bus.
