ref3 is ~1.505m above top of profile's plate.
center of sonic is 0.053m above top of boom
TRH is 0.37m below top of boom, thus top of TRH boom should be 0.42m above top of sonic boom.
In array 4:
Our measurements of profile:
Note that 7.x TRH of 5.886m is 2.1cm higher than desired and 8.x TRH of 6.787 is 1.1cm higher than
desired. We can't move the 7.x TRH lower due to Rohn internal braces, thus, we'll leave both
of these.
