Hello;
I have a hy-gain tower, modle HG-52SS. Tower is rated at 50 mph at 52
ft, with windload of 10 ft. I'm useing a 13 ft. mast with 4 antennas.
Wind load will be 10 sg. ft. The tower is a three section crank up. I
only want to crank the tower up to a height that would allow it to be
rated at app. 75 mph., need help to determine what height I should
crank the tower up to for a app. rateing of 75 mph. Also does anyone
have a est. windload for each ft. below 52 ft.
Any help would be greatly appericated.
Jim
