[amsat-bb] source for square aluminum tubing?

["Mark L. Hammond" <hammond@xxxxxxxxxxxxxxxxxx>]

Does anybody know of a good source for square, hollow aluminum tubing?  I'd 
like something about 1/2" on a side, to use for construction of a 2.4GHz 
helix (a la G3RUH's article).    Lengths of like 6' or 8' would be best 
(but a 4' length might suffice).

1" tubing is pretty easy to come by--old TV antennas ;-)  Even the local 
Home Depot has 1" square tubing.  But for 1/2", all they carry is steel.

Any weblinks, phone numbers, etc. would be appreciated.

Thanks!
