tomorrow. $25 each seems reasonable..
Yes, the price is reasonable but using it for antenna mast
applications comes with some warnings. Pipe is not rated for strength since it
just
carries liquids. I think I saw that pipe yield strength is down somewhere
around 30,000 psi - good enough for a tribander close to the top of the tower
or
VHF/UHF arrays in not so windy areas but not good for much else. Caveat emptor.
