Simple Ham Radio Antennas--Do small tuned counterpoises work with HF vertical antennas?


If you're having trouble viewing this video, please insert this title link into your browser searchbox: https://www.youtube.com/watch?v=9yARhBgi020. This is post #880 in a continuing series discussing amateur radio antennas. Great video tutorial from Peter Parker (VK3YE). Long radials are a hassle in a portable or emergency situation. Ground-mounted radial wires can present a safety hazard to both animals and people.  In this video, Peter uses a television rabbit ears antenna along with a variable capacitor to create a tuned counterpoise for his 20 meter vertical antenna.  The small tuned counterpoise system works very well and reduces the chances of someone getting tangled up in a ground radial system. Of course, Peter's location near a beautiful Australian beach helps launch a decent signal.  If you don't have sufficient room for a ground radial system, try this idea from Peter.

Comment:

If you have no room for a tower, but still want the performance edge extra height gives your VHF/UHF signal, you may want to try this intriguing idea from Glenn (N6FN).

Glenn has built a rig that "transmits significant power using a thin wire.  The wire is used to send the power at high frequency down the wire at which point it becomes more like a transmission line than a conductor."  Glenn adds that his signal " is rectified to DC on the other end to power a quadcopter drone" supporting the antenna wire.

Glenn has included some interesting graphics and a video showing the evolution of the drone supported antenna.

Simple Ham Radio Antennas--Vehicle Antenna Installation - NMO Mount (corrected copy)


If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v-hFR4SASOKhg. This is post #874. Like many of my ham radio friends, I use a mag mount antenna for my VHF/UHF mobile activity. While a mag mount is convenient, it can leave scratches and other imperfections on your vehicle's roof or rear deck. A really professional installation that looks nice, is weather resistant, and is more efficient calls for a NMO mount--the type that two-way radio shops use for Motorola radios in taxi cabs, police vehicles, and public service equipment. In this video, Commsprepper does an excellent job of taking us step-by-step through the process of installing a professional looking NMO mount. Be sure to connect the antenna system to the metal portion of your vehicle, since the car body serves as part of your antenna.  Because many vehicles these days employ fiberglass and other plastic parts in the car body, you may have to establish a crude ground radial system with copper strips below the NMO mount.

Simple Ham Radio Antennas--N4LQ Multiband Inverted L Antenna. Post #873.


If you're having trouble viewing this video, please check insert this title link into your browser search box: https://www.youtube.com/watch?v=uuD2mBZKHOg. Multiband antennas covering 160 meters to 10 meters tend to be very large, particularly when a quarter wave vertical antenna for the 160 meter band can be as tall as 135 feet/41.15 meters.  You could save some space and still get decent multiband performance by using an inverted L antenna that could fit on your property. In this video, Steve Ellington (N4LQ)  uses a 100 foot/30.48 meters (later upgraded to 200 feet/60.97 meters) long inverted L that covers all amateur radio bands between 160 and 10 meters.  He uses a MFJ-998 antenna transmatch (i.e. "tuner") to keep SWR in check.  Steve's project may give you some good ideas on building a similar antenna for your property.

Simple Ham Radio Antennas--How To Build A Delta Loop Antenna. Post #872.


If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=1uUVMaRFv4. My favorite amateur radio antenna is the easily-made and efficient delta loop antenna. In this video from Hiram Vazquez (WV2H), we learn the basic theory, construction, and performance parameters of this versatile HF antenna. Delta Loops display modest gain, have low noise, take up little room, and are inexpensive to build.  At my QTH, I have a delta loop similar to Hiram's.  The antenna's total length is 142-feet/43.29 meters and is attached to the top of a 33-ft/10.06 meters telescoping fiberglass pole.  The bottom portion of the delta loop is supported by two 10-ft/10.06 meters bamboo poles. The antenna is fed by a length of 450 ohm ladder line running into a 4:1 current balun. A short length of RG-8X coaxial cable connects the balun to my trusty Drake MN-4 antenna transmatch.  A small piece of RG-8X coax connects the "tuner" to my Swan 100 MXA HF transceiver.  My delta loop covers 40, 20, 15, and 10 meters with no difficulty.  Hopefully, Hiram's tutorial will give you some ideas on how to build your own delta loop antenna.  This is a great HF antenna!

Simple Ham Radio Antennas--How to Solder Powerpole Connectors. Post #870.


If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=vwkxSXmhAZY. Anderson Power Pole Connectors have many uses in your ham shack from connecting power supplies to transceivers to hooking up test equipment. In this well-produced video from Randy Hall (K7AGE), we learn a different method of attaching powerpole connectors to the various wires running through our radio rooms.  Until I saw this intriguing video, I always used the crimping method to attach the power pole connectors.  In this presentation, Randy uses a soldering iron/tool to attach the connector. Both methods will work and the choice is up to you.  Randy's news Logitech 920 camera does an excellent job of presenting this tutorial.

If you're having difficulty viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=GrqGrWyb4Xc. An antenna transmatch (i.e. antenna "tuner") is one of the most valuable tools you can have in your ham shack.  By properly matching the impedance of your antenna to the design impedance of your HF transceiver, you get maximum transfer of power from your rig to the antenna. The antenna "tuner" can help keep SWR at a low level, saving your rig from damage and reducing spurious emissions.

If you feel ambitious, you can build your own antenna "tuner" similar to this outstanding project from KK4WW & N4USA.  The "tuner" in this video is well-made, sturdy, and beautiful.

Here's another fascinating and enlightening antenna article from Don Keith (N4KC).

In this essay, Don describes five easily- made, simple, and inexpensive antennas that will get you on the air quickly after you've passed your amateur radio license exam.  These antennas can be made from locally available materials or from parts bought from the nearest hardware or home improvement outlet. You won't need expensive test equipment or tools to design, build, and use these basic HF antennas. All you need is an inquiring mind and the willingness to invest a few hours in making something that will work the first time. Don provides a simple formula for designing your antenna and outlines the pros and cons of each antenna in the article.

According to Don, here are the five basic antenna types that will get you on the air quickly:

The half-wave wire dipole.

The doublet with parallel feedline.

The quarter-wave vertical.

The horizontal loop.

The often maligned, but effective G5RV.

For each antenna, Don describes the basic theory and construction steps needed to build the antenna.  He also lists the advantages and disadvantages of each antenna.

In my 39 years as a licensed amateur radio operator, I've built variations of each of these antennas and wasn't disappointed by any of them.  They performed as expected and served me well over the past four decades.  I still use a 80-meter doublet fed with 450 ohm feedline as my backup antenna.  I've found an inverted V dipole useful in situations where space is limited.  Any one of these antennas can get you on the air quickly and easily.  Don't delay--build one of these antennas today and join your fellow radio amateurs on the air.
