Finishing construction of the 26ft tower

The tower and quad were installed in the summer of 2005 and it has withstood many 100 mph wind storms over 4 years and never once complained. We live on the border with Canada and get ravaged with many 100 mph wind storms each year. I was amazed that the tower dosnt even qwiver during the big windstorms. The added section to turn it into a 26ft tower is very sturdy. I had expected the tower might have at least a little sway during the big winds. But it stays as sturdy as a rock. Although I did place 5/8" threaded rod tie downs rather than using lag bolts. I also grounded the tower using a 20ft length of copper flex pipe as shown in pictures below. The ground connects to an 8ft ground rod placed directly under the tower.
