Another excellent antenna tutorial from David Casler (KE0OG).  This time, Dave tackles the controversial issue of which is better:  Vertical or Dipole Antennas?  Although Dave prefers Dipole antennas, his discussion is objective and straightforward as he compares the pros and cons of each antenna.  In many cases, your antenna installation will depend on the space available, with verticals preferred for small urban lots.  If you have a larger yard, you may want to consider a halfwave dipole. Both antennas will perform well if you pay attention to details.  For those who wish to experiment, try a vertical dipole for the amateur radio bands between 20 and 10 meters.  I've used a few vertical dipoles with good results.  Dave's explanations are clear and uncomplicated.  Dave recommends using Antenna Modeling...

The Christmas Holiday is being celebrated all over the world by Christian communities ranging from Northern Iraq to the United States of America.  Although most of the holiday festivities will be celebrated by Orthodox Christian communities a bit later (January, 2018), The feeling of goodwill is a welcome break from the  usual saber rattling and political posturing which have dominated the old year of 2017. On Hawaii Island, residents will get a bit of a white Christmas, thanks to almost a foot and a half/0.457 meters of snow on the upper slopes of Mauna Kea and Mauna Loa.  Check out the webcams at both sites to see how normally tropical Hawaii Island reacts to this dusting of snow. Listed below are three seasonal observations from three radio amateurs as they contemplate the holiday season: A Special Season's Greeting from Stan Gibilisco (W1GV)--https://www.youtube.com/watch?v=oBFdcgIBm7E&feature=em-subs_digest.  If that URL doesn't work, please enter the...

One of the major problems with vertical HF antennas is the establishment of a good ground radial or counterpoise system.  According to conventional wisdom, the ground radial system supplies "the missing half" of a quarter wave vertical antenna. In this video, Stan Gibilisco (W1GV) provides a working substitute for ground radials in a small urban lot.  The key is laying down as many 10-ft/3.048 meters ground radials you can and using the tallest vertical support (i.e. mast) available. While this solution is not as efficient as a full ground radial system using 1/4 wavelength wire, it will make your HF vertical antenna perform better than no radials at all.

For those of you who have some space in your backyard, a random loop antenna can offer some interesting possibilities.  When I was upgrading my new home in the Puna District of Hawaii Island a few years ago, I erected a 540-ft/164.53 meters horizontal loop on my property's spacious backyard, thanks to some 30-ft/9.146 meters Norfolk Pine Trees around the lot. The antenna generally followed the guidelines outlined in this video from Stan Gibilisco (W1GV). The key components of this experimental antenna were a balanced "tuner" (or a 4:1 balun/"tuner" combination), balanced feed line, and a good ground system for your station.  In my case, I used some speaker wire left over from a radio station news room renovation (I was working as a news announcer at the time for KHLO-AM 850/KKBG-FM (97.9 MHz), a roll of 300-ohm televisi...

End fed random length longwire antennas can perform remarkably well if you have a decent ground radial/counterpoise system and a way to match the antenna's high impedance to your rigs nominal 50 ohm input. In this video, "Signal Search" shows us how to match this antenna to your rig's input impedance with a simple 9:1 balun.  The balun is based on a design from the Emergency Radio Club of Hawaii (EARCHI).  This excellent video takes us step-by-step through the design, building, and use phases of this useful balun. Once the balun is built and connected to your antenna transmatch (i.e. "tuner"), you should be able to use your longwire antenna on any amateur radio band from 40 meters through 6 meters.  For more information, please visit this website: http://www.k5acl.net.

Operating an amateur radio station from deed-restricted housing (HOA/CC&Rs) can be a difficult, often frustrating experience. Yet, with a little ingenuity and creativity, a decent HF signal can be launched from your restricted home, apartment, or condominium location. In this video from N4CPB ("videosbymike"), we see how the popular Alpha Multiband HF Antenna can be used for amateur radio operations from a severely restricted space--in this case, Mike's Florida condominium unit. Mike's operating conditions aren't ideal. Please note that about 10-feet/3.048 meters of his antenna are blocked by the outdoor patio wall of his apartment.  Despite the restrictions, Mike is able to get some good contacts with this Alpha Multiband HF Antenna.  If you don't own one of these antennas, try making a small magnetic loop antenna...

Do you want a multi-band HF antenna, but don't have an antenna transmatch (i.e. "tuner") to keep SWR low as you select your favorite band? Then, a multi-band HF "Fan Dipole Antenna" may be what you're looking for.  The antenna consists of dipoles for each band connected to a single 50 ohm coaxial cable feedline.  In this video, Cory (N0ECK) and Alex (KD0YNH) take us step-by-step in designing, building, and using this simple, effective HF antenna.  According to Alex and  Cory, this antenna will work well on 80, 40, 20, and 15 meters without an antenna "tuner".  Be sure there is separation between the dipoles to reduce signal cancellation.  For the latest Amateur Radio news and information, please visit these websites: http://www.HawaiiARRL.info. https://oahuarrlnews.wordpress.com. https://bigislandarr...

If you've ever wondered what the 6 meter band holds for you, then check out this informative and laid back video from "Ham Radio Concepts" (KJ4YZI). The idea for this video came from a recent ARRL VHF contest which encouraged KJ4YZI to investigate the nature and challenges of "The Magic Band." The "magic" of 6 meters lies in its borderline location between HF and VHF, with the band showing characteristics of both HF and VHF.  Antenna requirements are modest, with a simple vertical or horizontal dipole offering plenty of contacts. KJ4YZI does an excellent job of explaining the theory, operations, antennas, and equipment needed to work this slice of the radio spectrum.  As an added feature, you get the antics of Sophie, the official mascot of KJ4YZI's ham shack. If you want a challenge in this time of...

Another excellent video tutorial from Dave Tadlock (KG0ZZ).  In this video, Dave reviews the basics of building HF/VHF cubical quad antennas. His presentation is clear, concise, and helpful. Dave does a good job of explaining the theory, construction, and operation of cubical quad antennas in a variety of operating environments. He also reviews the formulas used in calculating dimensions and spacings between elements.  Although cubical quads have been used extensively on the VHF/UHF amateur radio bands, they can also be found on some of the HF bands, including, 20, 15, 10, and 6 meters.  On lower HF bands (i.e. 40, 80, and 160 meters), quads tend to be quite large and bit unwieldy.

Operating on 160 meters from a deed-restricted home, apartment, or condominium unit can be a difficult challenge.  You can still pursue contacts in "The Gentlemen's Band" if you use some creativity and willingness to experiment with the materials you have on hand. In this video from "Ham Prepper", we see how a "junk bin special" can get you on 160 meters without nosey neighbors reporting you to the "housing police." In this case, "Ham Prepper" used some 300 ohm television twin lead, a MFJ-989c antenna transmatch (i.e. "tuner"), and a quarter wave length of wire for 160 meters to get on the air.  Although this antenna could be improved considerably with a better ground radial or counterpoise system, it does work.  You do what you can with what you have around you.  This video s...

Here's another great idea for a temporary portable or emergency HF antenna designed for field use.  In this video, GUERRILLACOM designs, builds, and operates an effective NVIS (near vertical incidence skywave) dipole antenna. NVIS antennas are effective omnidirectional antennas that can cover local, state, and regional communications requirements.  This type of low-level dipole antenna is perfect for local nets, roundtables, and "rag chews."  Just design the antenna for the lowest HF band of use, feed the antenna with balanced line, attach a 1:1 or 4:1 current balun, run 50 ohm coaxial cable from the balun to your antenna "tuner", and you're ready to go.

This video is another great production from Ray of the "Radio Workshop" in the UK.  In this video, Ray provides all of the theory, construction practices, and uses of the classic "doublet antenna."  This old design can be used for both single and multiband use, depending on what feedlines and antenna lengths you choose. If you prefer the multiband approach, then this video is for you.  The concept is simple:  build a dipole antenna for the lowest frequency of use, feed the antenna with balanced line (300 ohm tv ribbon, 450 ohm ladder line, or homemade 600 ohm balanced line), run the balanced line into an antenna "tuner" that handles balanced line or connect the balanced line to a 4:1 current balun, and use a small length of 50 ohm coaxial cable to connect the balun to your antenna "tuner."  Place the ...
