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.
According to Hank, the expenditure of around $300 US for locally available materials should provide all of the components needed for this sturdy mast.
The most important part of the mast is the selection of the pipe needed to support your antenna:
- "I used two different sizes of standard schedule 40 black iron plumbing pipe: 2" for the base and lower section, and 1-1/2" for the top section. 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 zinc coating makes the welding troublesome. Since I wanted to paint it flat gray anyway, black pipe was the best choice. Here are some specs on the pipe, 2-1/2" is also shown in case you are thinking about going a size bigger:
1-1/2 1.900 1.610 2.72
2 2.375 2.067 3.65
2-1/2 2.875 2.469 5.79"
Hank provides a good selection of photos and diagrams to help you design your own tilt-over mast. If you're uncertain about raising this structure, please ask some of your fellow hams to help you. This tilt-over mast project would be an excellent club project for the annual ARRL Field Day exercise or for a portable operation away from your home.
