[Towertalk] small diameter aluminum tubing

[n4zr@contesting.com (Pete Smith)]

Is there a non-radio/hobby/hardware source for 1/4" OD aluminum 
tubing?  Maybe in the model airplane world?  I know copper is readily 
available in the plumbing section of Home Depot et al, and maybe that will 
do, but if aluminum can be found I suspect it would probably be 
sturdier.  Application is elements for a 136-MHz Moxon rectangle, in an RFI 
DF setup.
