A vertical on a slope (or cliff) means that the dirt in the far field

"Take-off angle" is a seriously flawed concept. Better to think about
absolute field strength in the vertical plane, as I pointed out in my
observations about interpreting models the compare antennas. :)
One of Tom's important observations that I failed to mention in the
first post about it is that the drone data showed significant field
strength below 0 degrees elevation in the direction of the drop-off.
