Hi Roger, if you think through this you will see that in the worst case one of
the four guys is taking all the forces. When the wind is blowing directly in
line with one of the guy anchors, the back guy takes none and the two side
guys are at right angles and can also take no load. This is exactly the same
worst case as for a three way system, one guy anchor has all the load.
The foldover numbers work because the towers are short, 48, 58 or 68 feet tall
and the sections are designed to handle heights up to 200 feet for 25G or 300
feet for 45G.
The same numbers have to work for short regular 25G and 45G towers but for
whatever reason Rohn has decided not to publish the data.
These considerations explain how many hams get away with grossly overloading
(according to published data) 25G, 45G and 55G towers.
Tnx/73 de Gerald, K5GW
