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
Hi All I am going to be ading to my tower collection & would like some input on putting a 31 foot long 432mhz beam on a rohn hbx56. I know rohn says no boomlengths longer than 10' but this antenna on
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

Steve is prejudiced against the BX series of towers. I have had one (same one) up at two places --Dallas and here in Fla.-- and like its performance. Never had a rotor shelf problem, It is still stan
