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:
Size(inches) OD(inches) ID(inches) Weight(lbs/ft)
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.

G5RV Multi Band HF Dipole Antenna. Post #1555.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=aeNHIQ_j4Dk

This well-produced and richly illustrated tutorial on the classic G5RV HF Dipole Antenna was presented to the Brandon Amateur Radio Society in Brandon, Florida in 2017 by Bernie Huth (W4BGH).  Bernie does an excellent job of  explaining the pros and cons of this popular HF antenna from the late Louis Varney (G5RV).  Although Varney envisioned his design primarily as a 3/2 wavelength antenna for the 20 meter Amateur Radio band, radio amateurs have used the antenna for multiband use.  The G5RV is an excellent choice for the 20 meter band.  Performance on other HF Amateur Radio bands is good enough to qualify as stand alone HF antenna if you can only erect one HF antenna.

Amateur Radio Bicycle Mobile Setup. Post #1554.

Here's a way to use Amatuer/Ham Radio while you work on shedding a few pounds in useful exercise.  Why not equip your bicycle for 2 meter/70 cm mobile operation?

In this short, well-made video, "taverned" shows us how he used a mag mount antenna, a simple C clamp, and a basic ground system to convert his mountain bike into a mobile station.  The project is straight forward, simple, and gives you emergency communications while you peddle down the road.

An 80-Meter Vertical Helix

Like many amateur radio operators, I live on a small lot surrounded by neighbors, utility lines, and civic-minded citizens concerned about the "attractiveness" of my community.  Whether by design or outright fear, I've adopted the "stealth" approach to ham radio antennas.  It's the old "out of sight, out of mind" idea applied to amateur radio antennas.

The amateur radio press is full of articles describing the struggle of amateur radio operators to pursue their hobby under the burdensome regulations of CC & Rs, HOAs, and other civic minded citizens who object to antenna farms.  So far, my modest verticals, loops, and inverted vees have blended well with the vegetation and trees bordering my small backyard.  Vertical antennas have always been a problem because of the limited space for a radial system.  There are times, however, where a shortened vertical for the lower HF bands (such as 80/75 meters) is necessary where horizontal space is lacki…
