New Rohn 55 Tower Installation, Summer/Fall 2010

After an accident in the Fall of 2009 took down an 85' tower and 6 antenna, I realized it also gave me a clean slate to work with. I acquired about 28 feet of 5" X 7" X 3/8 "tool bar", perfect for making guy posts. Over the winter of 2009, these were built and Rohn 55 tower sections were secured. 

In the Spring of 2010, site work was begun. The holes for guy posts (2' X 4' X 5')and tower base (33" X 33" X 54") were all slightly larger than spec called for, and a total of 5 yards of concrete were poured. Plans were to allow it to cure for the requisite 30 days, but the summer of 2010 was much hotter in Louisiana than usual. We had several record breaking high temp days, and a long string of over 100 degree days as well. This caused most outdoor work to be put off until temps break in the fall. Since it was previously owned, the entire tower has been cleaned and re-shot with cold galvanize.

Another view of tower base                                                    Yes, it IS plumb

Fall 2010, Stacking Day - Its finally cool enough to work outside. 

We got 96' stacked the first day, and finished at a height of 124' the next week.

The 3 TIC rings were installed on the ground - MUCH faster than in the air.
