    It's 5 of one and 10 of another. If you use a 5-footer, you wind up with 
all complete 10 foot sections when it's time to remove the tower. If you use 
a 10-footer in the concrete, you've got to chop it off and you wind up with a 
tower 5 feet lower next time you put it up. 

    Don't forget to put 4-6" of gravel in the bottom of the hole and set the 
section directly on the gravel so the legs will drain of water condensation.
