160 meter antennas can be intimidating.  A full quarter wavelength vertical for "The Gentlemen's Band" can be a high as 135 feet/41.15 meters. Even a horizontal dipole or inverted vee can challenging.

K6MN has solved this problem by designing, building, and using a vertical helix for 160 meters.  Iv'e use such an arrangement for my 80 meter vertical, and, with a good ground radial system, I can do quite nicely on 80 meters.  K6MN takes that idea and models it for 160 meters.

This antenna is suitable for restricted land areas and housing governed by CC&Rs and HOAs.  His final product is "stealthy" and blends in well with the trees on his property.

In this post, we find a complete photographic step-by-step tutorial, a list of materials, and places where you can download a supplementary instructional manual.

Basically, the antenna is a half wavelength of wire wrapped helically around a 25 foot/7.62 meters PVC pipe, capped off with a capacity hat, and fed with a length of 50 ohm coaxial cable.  Lay as many ground radials as you can.

An antenna transmatch (i.e. "tuner") will help keep SWR under control.  The antenna is fairly narrow banded, so frequent adjustments will be needed to take advantage of the entire 160 meter band.

According to K6MN, the antenna can be built for around $90 and will take approximately 10 hours to build.  Have fun!

G5RV Multi Band HF Dipole Antenna. Post #1555.

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…
