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

Image
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.

Simple Ham Radio Antennas--HF-Powered Drone Antenna. Post #878.

HF-Powered Drone Antenna (http://www.hackaday.com/2016/08/hf-powered-drone-antenna). (http://www.eham.net/articles/37439). Reporter:  Elliot Williams. Please click underlined title link or enter the title URL into your browser search box to read the full report and to see the video of the experiment. 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. For the latest Amateur Radio news

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

Image
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 h

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

Image
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.

Image
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 &quo
