Simple Ham Radio Antennas

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=GEDneotW3ko With the ARRL Field Day rapidly approaching (last full weekend of June), it may be time to consider what antennas will be used in this annual emergency field communications exercise and contest.  Now that propagation is favoring the lower HF bands (40, 80, 160 meters), you may want to consider a specific antenna for each band.  In this Field Day video from 2016, "Ham Prepper" shows us how his club solved the height issue on 160 meters with a balloon-supported 1/4 wavelength antenna. After some preplanning and the collection of a skilled crew, the balloon-assisted antenna was launched successfully.  This somewhat unusual antenna produced good contacts for the club and helped boost its overall score. Make a few experimental HF antennas, test them in a nearby park or field, and prepare for some fun at the end of June. For the latest

In this video, Stan Gibilisco (W1GV) shows us how to build this unusual antenna and describes its advantages and drawbacks.  The antenna is fed with open wire (300 ohm twin lead, 450 ohm ladder line, or homebrewed 600 ohm feed line) and uses an antenna transmatch (i.e. "tuner") with optional balun to reduce RFI and SWR. The space between the top horizontal antenna element and the bottom antenna element is approximately 12 inches /30.48 cm.  The antenna is capable of multiband operation.  If you're looking for a different kind of dipole, then the three-wire dipole may be what you're looking for.

In this video, Dave Casler (KE0OG) does an excellent job of making often complex antenna theory easy to understand.  Dave takes us from simple dipole and vertical antennas to a basic overview of gain antennas, pros and cons of "traps", and how to choose the right feed line for your new antenna.  This video would make an excellent introduction to antennas for both new operators and the experienced ham who may have gotten a bit "rusty" on antenna theory and application.  Dave's presentation is clear, informative, and often entertaining.

In this video, Michael Martens (KB9VBR) discusses baluns and chokes and how these components can prevent RF energy from traveling down the outside of your coaxial cable and creating needless interference to your electronic equipment. Michael does an excellent job of explaining common mode currents, baluns, and RF chokes.  If you use coaxial cable to feed your HF/VHF/UHF antennas, then this video is for you. Keep a copy of this video in your reference library and refer to it whenever you need a balun or choke for your antenna system.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=KQJw9j-moEg Here's all you need to know about NVIS (near vertical incident skywave) antennas.  Kevin Loughin (KIB9RLW) provides an excellent review of the theory, construction, and use of NVIS antennas. As an added bonus, he analyzes the pros and cons of the Chameleon MPAS (Modular Portable Antenna System). If you need an effective antenna for local, regional, and state-wide coverage, then a NVIS antenna may be what you're looking for.  Kevin does a good job of explaining where these antennas fit into the overall antenna portfolio of an amateur radio station.  For the latest Amateur/Ham Radio news and information, please visit these websites: http://www.HawaiiARRL.info. http://www.arrl.org. http://www.arrl.org/arrl-audio-news (a weekly podcast which is updated every Friday afternoon). https://oahuarrlnews.wordpress.com. https://hamradiohawaii
