Check out the item on this subject in the Hints and Kinks section of QST for April of this year. It is 2 or 3 sections of uni-strut fastened together. This material is available at Lowes, Home Depot, etc. It would need to be guyed, but it is a cheap alternative. I also know people who use large diameter heavy gage PVC pipe.
