Simple Antennas for the Amateur Radio Operator--a continuing series


During a recent read of the articles posted on, I came across an interesting antenna story by Dale Kubicheck, N6JSX (12 June 2012).  The article entitled "HF 18VT Vertical Fence Mounted With an Ugly-Balun" caught my eye because of the way this ham recovered, rejuvinated, and restored an old vertical antenna to its former glory.  This article contains a series of pictures and descriptions of the creative process leading to a semi-homebrew antenna that really works.  Once Dale rewound a few coils, cleared the corrosion from the antenna sections, and fashioned a new balun, he attached the antenna to a chain link fence, which formed part of his counterpoise system.  Although he may need some radials in the future, the antenna apparently delivers the results Dale wanted.  Dale's pictures and explanation are excellent.

Eventhough you may not have the tools Dale uses, you can still make a good antenna with what you have on hand.  Even an old 108" CB whip can be modified to perform well on 10 meters.  Check out the ads for the Solarcon A-99 vertical, which is only a modified CB antenna.  Many amateurs have used this antenna with a decent radial field or counterpoise system to work stations from 20 meters to 10 meters.

I once lived in a house that had a wooden fence surrounding most of the yard.  I used the 5' high fence to support a 40-meter loop.  The antenna was nearly invisible unless you looked closely at the fence.  This antenna worked all bands from 40 meters to 10 meters when I fed it with 450-ohm balanced line, balun, and a tuner.  Although most of the radiation went straight up, I managed to snag many DX contacts.  The antenna was great for NVIS applications, such as local rag chew and emergency nets.  I have a 40-meter loop under my house for that very purpose.  The loop also works as a great MF and SW antenna for my Hallicrafters SX-62A.

So, let your creativity loose.  Use what you have on hand or can buy locally.  Your local hardware or building supply store can provide you with all kinds of things--wire, pvc poles, connectors, tools, etc.  Also, don't be afraid to ask your local cable company for any unused lengths of RG-6 coax.  You might get lucky and stumble upon 50 or more feet of this cable.  I've used RG-6 for patch cords and antenna feed lines.  The slight mismatch of this cable (75 versus 50 ohms) can be handled by most antenna tuners.  A careful search through various on-line catalogs can help you find suitable connectors which will enable you to convert the type F connectors to UHF connectors for your rig.

You are only limited by your imagination.

Have an excellent day!

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: 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.

If you can't see the video, please insert this title URL into your browser search box: 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 lack
