Hi:
I put in a search for
military mast
on ebay and came up with a bunch of items for very good prices...one person
had 12 sections of 44 inch masting with carrying case and guy lines for $24
buy it now.
Some of the other ones aren't as cheap, but they are certainly inexpensive.
Just remember with these kind of light weight masts, they have to be guyed
if the height is over about 20 feet because of the tendancy to sway allot.
