Did you consider a fold-over tower? The fact that you say you cannot use
guys suggests that you are space limited? I have a very nice motorized 72
ft. fold-over Heights tower, PE rated for 35 sq ft of antennas in a 70mph
wind zone. Tower apex is at 78 ft when erected. You did not say what the
beams were, so hard to judge if something like that would work for you.

Subject: [TowerTalk] Am I asking for trouble? - tower loading
I would like to get everyone's opinion on this -
I am planning on installing a US Towers crankup tower. These towers are
rated for windloads at 50mph and 70mph. I want to stack 2 beams on the
tower. These 2 antennas would exceed the tower's windload rating at 70mph
but would be well within the rating for 50mph. I plan to install a wind
speed meter and deligently crank down the tower every time the wind exceeds
50mph.
I cannot install a guyed tower at this location so this is my only option.
The crankup with these antennas and cranking it down in winds over 50mph is
my plan. Am I asking for trouble in doing this?? Thanks.
