If you take a drone with a camera, tie a string or a 100ft. measuring tape to it, and take it up until you get LOS with a tower(if you can see it with the camera), and measure the distance of the string or the tape to get your needed tower height.
OR
Ziptie a mobile hotspot to the drone that has strength of signal info you can access via laptop or phone, attach the string or measuring tape, and once you get to maybe 40 ft., slowly rotate the drone until the signal maxes out. Repeat at different heights as the battery of the drone allows, until you get the best direction and height.
Sounds stupid?
