Comment:  Have you ever wanted to have a strong, reliable, and fairly inexpensive antenna mast for your ham shack?  If you don't want to spend a lot of cash for such a project, Hank's (WV7U) Tilt-Over Mast may be what you're looking for.

This pipe comes in 21' lengths. Galvanized plumbing pipe of the same size would be OK too, but it was about 50% more expensive, and the zin
