For a homebrew short-boom yagi antenna project, can one use electrical conduit pipe for the boom, or would you be better off using aluminum tubing? Is electrical conduit piping generally made of galvanized steel (weight issue?), as opposed to aluminum? Any suggestions would be appreciated. 73

Use aluminum. Conduit (EMT) is steel. It is thin walled and not very strong. It will rust over time.

And EMT is designed to BEND, a common step in installing
electrical conduit.

Aluminum is  a much better choice.

Yes, aluminum is the best. I found that out the hard
way many years ago when I built quads. The EMT bends
too easily.
