In fact, many good aluminum/copper/stainless flats, rods, tubing, etc
can be found for antenna projects... yellow pages should provide anyone
with a source...

One should be careful when using aluminum conductors for antennas.
ACSR (Aluminum Conductor Steel Reinforced)
may be a better choice for tensile strength.
but Aluminum oxide is an insulator. and it forms easily at the connections.
But I have made some good antennas out of Aluminum Arrows
I even left the fletching (feathers) on for a couple of antennas. :-)
