Us Towers HDX 589 worked great for me for several years. I had about 37 sq
feet. 40 meter 4 element 52 ft 3 inch boom and 5 element 20 meter OWA 36 ft 3
inch boom. about 17 feet above that.
Other antennas and two big tilt plate double wall very heavy mast. Heavy Orion
rotor etc Approximately 439 lbs of weight . Ran that about 5 years. Always
cranked it down to where the sections overlapped during high winds or all the
way down when in our tornado season.
Towered worked just fine.
I did watch my tower closely as I was advised by US Tower I was pushing it.
Good luck on the opposition!!
