[TowerTalk] Boom size?

[Ed Stallman]

 I'm gathering parts to build a 6M beam , 7 elements on a 30 foot boom.
here's what I have in mind for the boom, let me know if you thing it will
be strong enough.
The center section will be 12 foot 1-1/2 X 1-1/2  .125 wall, (square stock)
The 2 end's will be 9 foot 4 inch each 1-1/4  X  1-1/4   .062  wall.  The
elements are .405  .062 wall.
The center section WT=  10 LB's . The end's WT = 3.5 LB's each. All 7
elements WT = 5.5 LB's . For support I will use Overhead Dacron rope.
So what do you think the wind Survival of this antenna will be??
