So that would place the  quad boom about 15ft above the  rotator..
Then at the very top I would have a 2m/440  vertical


    Umm, maybe. What's your county windspeed rating?  You can look it up at 
_www.championradio.com_ (http://www.championradio.com)  under Tech  Notes. 
 
    Then you need to calculate your proposed load at  that windspeed. 
There's at least one online spreadsheet to do it or you can  spend ten bucks and 
get the Mast, Antenna and Rotator Calculator (MARC)  Program from 
_www.championradio.com_ (http://www.championradio.com) .  

THEN you'll have the answer to your question.  Anything else is a pure 
guess.
