This is an old message but it points out the foolishness of using only boomlength as a measure of antenna torque. For the 432 MHz beam in question, it could also considered equivalent to a 20M rotata

First of all, Yellow Medicine County is an 85 MPH windspeed zone. The HBX56 is rated at 10 sq.ft. at 70 MPH. Since you'll be using the BX-2 section as the top section, it's better than the smaller BX

Let me elaborate on the windspeed situation. At 70.7 MPH, the wind pressure is 20.0 pounds per square foot. At 85 (actually 86.6) MPH, the wind pressure is 50% more at 30 psf. Now you're really pushi
