Whoosh. Yesterday the mast bent over in the strong wind as we watched. Just lucky but I went down to the Parker site for another reason and happened to be there when the wind was at it’s peak. The guys on the south side needed tightening. I had never seen the tower in strong wind so this was a good learning experience. I tightened the guys and the tower was ok. The mast on top was bobbing and weaving. I was feeling relieved the aluminum was allowing the flexing. Oops. Snap. While I was standing there watching along with the landowner we saw it happen. Guess it wasn’t all that flexible after all.
Today I lowered the tower and cut out the damaged portion of the mast. I also lowered the next telescoping section down inside the bottom section to provide double wall strength. Now it’s only 46 feet tall instead of 50. Modelling with EZNEC shows a slight improvement at 15 degrees. Go figure. Can you tell it’s 4 feet shorter? We’ll see if the on-the-air performance changes any.
