Big steel works the same way (at least with the KFI tower in Los Angeles). 1" guys on the bottom (13,000# tension), 1-1/4" guys on the top (20,000# tension).

The top guy is 550' up the 750' tower. The ground anchor is 550' from the base of the tower. Both the upper and lower guys connect to the same anchor.


......but, if you check your Rohn book, you will notice the lower guys are
usually one step down in size.  If the upper ones are 1/4, the lower  ones
are 3/16.  Therefore, less tension when tightening the guys on the
bottom....less pull.
