[TowerTalk] Rotator Swap U.S. Tower Crank-Up

[Mac]

I second what Joe proffers,  I lost [dropped] my mast last year about 
10-12 feet weighing near 350-400 pounds with all included,  and geez oh 
Pete,  a small bottle jack was all i could get to fit in the 
circumstances,  and to get all the mast back up took lot of work to at 
my guess was about 5" of lift from the jack per effort then reset the 
clamps and start the whole sequence all over till it was finally raised 
back up and in place... watching paint dry would have been more fun..
