I'd like to design and build a new 2-meter Yagi antenna, and would
like to construct it using aluminum tubing and rod. Drawn tubing--the
stuff with an axial seam--would suffice.

Anyone know of a good source for this stuff in Washington DC or nearby
areas in Maryland? I've tried Home Depot and the like, but the stock
available in these places is incomplete and expensive.
