Where I am,there are gusts of wind that are alarming me at this time. I have those radio antennas(Police scanner radios,and Shortwave receivers,and a transmitter antenna) on the roof. One of those antennas is about 23 feet tall,and that's not including the mounting mast. That one has guide wires to keep it in place,so that should help. It's a major job task to put them up,and I did all of the work. BF
