Comment:

If you have a limited area to erect a multi-band HF Dipole Antenna, you may want to consider this vertical HF dipole antenna from DJ0IP.

The illustration provided by DJ0IP provides all of the information you need to design, build, and operate this simple, elegant design.

Here's the list of  basic materials for this antenna:

A telescoping fiberglass antenna mast 12 meters/39.36 ft long.  DJ0IP uses a Spider Beam fiberglass pole to support the antenna.

6 meters/19.68 ft of wire for each antenna element for a total of 12 meters/39.36 feet.

A homemade antenna center insulator.  Each antenna element is wrapped in a loose spiral for each half of the fiberglass pole.

A convenient length of 450 ohm open wire feed line.

A balanced tuner, such as the MFJ-974B.

Three kevlar guy ropes to stabilize and support the mast.

Ground stakes 5-7 meters/16.4-22.96 ft spread an equal distance from the base of the mast.

The bottom antenna element should be about 50 cm/19.68 in above ground.

--------------------------------

This antenna would be suitable for both home and portable use.

N9SAB Half Square Antenna-Field Test. Post #1476.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=_JR9v0YeI.

Excellently presented test of N9SAB's 20 meter Half Square Antenna by "Outdoors On The Air."  While the half square antenna is a bit more complex than a simple random wire or dipole, it does show some gain (around 3dB) broadside over a dipole antenna.  In this video, "Outdoors On The Air" assembles, erects, and uses a half square antenna built by N9SAB, and shows the DX capability of this phased vertical array despite being only 20 feet/6.097 meters above ground.

While the antenna can be erected by yourself, you may need some help to make sure the antenna elements are properly supported and aligned.  Although the half square can be used in portable operations, it may be best suited for a permanent installation.

Over the past several years, the Big Island Amateur Radio Club (Hawaii Island) has used half square antennas for 80 and 40 meters with excellent results.  If you really want 'to push the envelope", have your club build a multi-element sterba curtain array.  As a Field Day antenna, the half square and its distant cousin, the sterba curtain, have proven to be reliable DX getters.

Field Day 2016-Yaesu FT-817 QRP HF Portable. Post #1473.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=YwH8HUCjBDE.

If you can't join a local Amateur Radio club for the upcoming ARRL Field Day (23-24 June 2018), why not operate solo from your backyard or the nearest public park?  Over the past several years, I've done just that because of employment conflicts or family matters.

In this video from "Outdoors On The Air", we see what can be done with a simple, portable antenna, some good camping gear, and a small QRP rig such as the Yaesu FT-817 ND.  You can opt for the antenna described in this video or you can bring along a pre-made dipole or inverted vee antenna for your station.  You don't need much to get on the air and enjoy this annual Amateur/Ham Radio event.  Of course, there's not much you can do about hot, sticky summer weather or the persistent problem of biting insects.  Bring some insect repellant, some extra food, and plenty of water.  Operating a 1A,1C, or 1B station can be a lot of fun.

Comment:

I'm always looking for new antenna ideas, especially when the ARRL Field Day rolls around (23-24 June 2018).  I discovered this fascinating article by John Huggins (KX4O) during a cursory glance through the https://www.dxzone.com website.

According to John, this post is a "discussion of (the) asymmetrical hatted-dipole antenna, a portable antenna that can be used for field day, sota, campings, or even for fixed installations..." John adds that the AHDA is a "free standing 20-10 meter antenna that is really easy to build...and easy to carry."

John takes you step-by-step through the design, building, and use process with an ample supply of photos, performance graphs, and actual field tests of this uncommon antenna.

John used parts from DX Engineering to build the basic antenna, including aluminum tubing, a resin support column, and miscellaneous items.  A sturdy tripod speaker stand supported the antenna, while a homebrewed choke balun made from RG-316 coaxial cable and a Type 43 toroid finished the project.  John said he spent around $250 for the entire project, which is suitable for both home and portable operations.

Even if you can't commit the time and money to build this antenna, the design contains some interesting features worth your attention.

Inverted L Antenna for the TOP Band. Post #1471.


Inverted L Antenna for the TOP Band. Post #1471.

http://www.ai4ji.com/Projects/160minvertedl.htm.

Author:  AI4JI.

Accessed on 23 April 2018, 2129 UTC.

Please click link to read the full article.

Comment:

Now that the solar minimum is with us, radio amateurs are exploring contacts on the lower HF bands, such as 40, 80, and 160 meters.  LF and VLF enthusiasts are equally busy experimenting with antennas for 630 meters (472 kHz) and 2200 meters (137 kHz).

Antennas for these bands tend to be large and present coil and matching problems, resulting in low efficiency and power loss.

According to AI4JI, an inverted L Antenna designed for 160 meters (the TOP Band) can circumvent some of the more difficult matching problems.  In this brief post, AI4JI outlines a simple 160 meter inverted L Antenna built with commonly available parts, including 14 AWG stranded copper wire, three insulators, a 300pf-500pf variable capacitor, and a simple ground radial system.  For single band, 160 meter operations, you can use 50 ohm coaxial cable, such as RG-8 or RG-8X, as your feed line.  An antenna transmatch (i.e. "tuner") would be useful as well.  Try to use as many ground radial wires as you can fit on your property.   W0BTU recommends a basic ground radial system consisting of 35, 50 ft/15.24 meters-long buried wires.

How to make a Ham Radio Speaker Wire Antenna. Post #1470.


If you can't see the video, please insert this title URL into your browser search box://https://www.youtube.com/watch?v=cqh0Ntus5G0.

A field portable or emergency HF antenna doesn't have to be fancy, expensive, or heavy.  In this video from KG6HQD, we learn how an antenna designed for SOTA operations (Summits On The Air) evolved into a simple, practical, and inexpensive HF antenna for both home and field use. 

Although the speaker wire antenna was designed for the 20 meter band, KG6HQD says his new Elecraft KX2 can work stations from 40 through 10 meters "with ease."  If you're looking for a good portable HF antenna, consider using ordinary speaker wire for the antenna elements.  You can make one of these antennas for emergency home use and another for portable or field use.

Modeling the Simple Inverted Vee Antenna, #102. Post #1469.


If you can't see the video, please insert this title URL into your browser searchbox: https://www.youtube.com/watch/v=oFE142IMo-s.

One of my favorite HF antennas is the classic inverted vee dipole--simple, effective, and inexpensive.  In this video from David Cassler (KE0OG), we get a full tutorial on this basic antenna which still serves radio amateurs today.

Dave says a few basic antenna modeling tools, such as EZNEC+, reveal a lot of vital information about this popular HF antenna, including the effect of height over ground, the amount of spreading between elements, and the type of mast used to support the inverted vee.  A properly designed inverted vee is the perfect antenna for both portable and home station use.

Ham Radio-Ground Spike Antenna. Using the earth to receive LF and VLF. Post #1468.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=jHK7kKsVVw0.

Here's an interesting, unconventional antenna that could open an entire new world of radio listening.  In this video from Kevin Loughin (KB9RLW), we learn how to use what Kevin calls a "Ground Spike Antenna" to tap directly into the earth for LF and VLF signals.  Now that radio amateurs in the U.S. and elsewhere are able to transmit in the 630 and 2200 meter bands, antennas such as the "Ground Spike" could help you explore the largely untapped universe below the standard AM broadcast band.  Kevin does an excellent job of showing just how easy it is to tap LF and VLF signals by using the earth as a key antenna element.  Build one of these antennas and prepare for some unusual listening, courtesy of the earth itself.

How To Build A Delta Loop Antenna. Post #1467.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=1uUVMaRFMv4.

In this well-made video tutorial, Hiram Vazquez takes us step by step through the design, construction, and use of a Delta Loop HF Antenna.  As Hiram explains, delta loop antennas are fairly quiet on receive, show a bit of gain over a dipole antenna (about 3dB), take up little space, and are cheap to build.  Delta Loops can be both mono band and multiband, depending on how you feed the antenna.  If you use balanced feed line (300 ohm tv twin lead, 450 ohm ladder line, or home made 600 ohm balanced line) with a balanced "tuner", multiband use is possible. If you can use only one HF antenna on your property, the delta loop may be what you're looking for.

ARRL Field Day 2016 With Chameleon Antennas. Post #1466.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch/v=uymwEzqgVAc.

Over the next few weeks, I'll be featuring some interesting antennas that you can use for the upcoming ARRL Field Day on 23-24 June 2018.  Although many of my fellow radio amateurs will join their club at public parks, schools, and emergency operations centers for this annual communications exercise and popular contest, some of us (including yours truly) will be operating a single station on battery or solar power in whatever space we can find.

In such situations, our antennas must be versatile, sturdy, and easy to erect.  In this report from "VideosByDPF", we see an excellent "one-man" ham station using a variety of antennas, including the Chameleon Hybrid Mini and the P-Loop Magnetic Antenna.  This video was shot at the 2016 ARRL Field Day when propagation was beginning its slow decline from previous years.  Despite the generally poor conditions, this portable station did fairly well using the Chameleon magnetic loop antennas.

Hopefully, this video will give you a few ideas on how to operate under field conditions with simple antennas.  Part of the fun of Field Day is testing your antenna ideas under portable or emergency situations.

Field Testing Vertical Antennas for Ham Radio, Post #1465.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=OwMb6dHEnII.

Vertical antennas are a good choice for many portable and home ham radio stations. But, how well do these antennas actually perform in the field?  In this video, N5CFB, KG5PWA, and K5ACL test three popular vertical antenna designs.  While all antennas performed well, some were easier to match and operate than others.  Interesting "live" test.

475 kHz and 137 kHz Winter antenna checks in Alaska. Post #1464.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=)3LMlp3oq1w.

Antenna research continues forward as radio amateurs take advantage of newly permitted operations in the 630 meters and 2200 meters (475 kHz and 137 kHz) amateur radio bands.  As this video from "hellozerohellozero" points out, size isn't the only concern of those operating far below the standard broadcast band.  Weather and other environmental issues can make use of these new bands a bit challenging.

In this video, we get a glimpse of what one Alaska (KL7) ham is doing to keep his low frequency antennas operational.  All of this takes place with a stunningly beautiful look at Alaska's natural beauty.  Enjoy!

Comment:

Why not try a new antenna for the upcoming ARRL Field Day on 23-24 June 2018? The compact HF multiband antenna described by NC4FB may be what you're looking for.  This antenna is based on a design my G7FEK (http://www.g7fek.co.uk/software/G7FEKantenna.pdf) and will cover all Amateur Radio bands between 80 and 10 meters. An antenna transmatch (i.e. "tuner") is required for 17, 15, 12, 10, and 6 meters.

According to NC4FB, this compact antenna has several good points in its favor:

Small size
Uses 50 ohm coax as an antenna feeder.
Multiband operation between 80 and 10 meters.
Low angle of radiation (good for DX).
Easy to build, set up, and take down.

This antenna can fit on most urban lots and is suitable for both portable and permanent installations.

While this antenna from K7PP will prove to be a bit challenging for a Field Day operation, it could be ideal for a home site with plenty of room.  Fan dipoles using a common feed point attached to several band specific antennas have been popular for decades.  The elimination of an antenna "tuner" could be an advantage for those who prefer separate dipoles but can only use one feed line.

K7PP designed this antenna to cover 80, 40, and 20 meters with one feed line.  Ten meter operation is possible using a harmonic of the 80 meter band.

Balloon Antenna Field Day 2016. Post #1458.


If you can't see this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=GEDneotW3ko.

Here's an interesting antenna idea for those seeking a good 160 meter antenna for the upcoming ARRL Field Day in late June 2018.  How about using a balloon-supported 1/4 wavelength antenna for "The Gentlemen's Band?"  Be sure to plan ahead and check with your local airport to make sure your balloon-supported antenna doesn't present a threat to low-flying aircraft.  According to the "Ham Prepper" team, this balloon-supported antenna did very well that weekend two years ago.

Comment:

The ARRL Field Day emergency communications exercise and contest is coming to a site near you on the last full weekend of June 2018 (23-24 June).  Why not build a simple, inexpensive, and effective antenna for your Field Day operation?

The antenna experts at https://www.dxzone.com have compiled a list of five multiband wire antennas that will keep your log book full of contacts, whether or not you operate contest style during that weekend.

Here are the five multiband antennas you should consider for your next portable or field operation:

The W5GI Mystery Antenna.  This antenna is similar to the popular G5RV, but is a better performer, especially on 20 meters.

The 6-band Windom Antenna from ON4AA.  This trapless off-center-fed dipole works well on 80, 40, 30, 20, 15, and 10 meters.

The VK5AH-HF 4 Bander Dipole.  This antenna is a good choice for 80, 40, 20, and 15 meters.

The dual band wire beam for 17 and 12 meters from Allen Baker (KG4JJH).  This antenna is a Moxon configuration that works especially well on 17 and 12 meters.

The H-Pole Multibeam Antenna from HB9MTN.  This vertical antenna can be use on all amateur radio bands between 160 and 10 meters.

---------------------------------------
Hopefully, this article will give you some new ideas for your home or portable station.

80m Pedestrian Mobile Antenna experiment. Post #1455.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=JdGvjRyo0LM.

If you want to try some fascinating antenna experiments, consider operating pedestrian mobile on 80 meters.  With a little ingenuity, a coil loaded wire on fiberglass rod, and a trailing radial wire, you could have some real fun.  Martin (VA3PCJ), Mark (VA3UPM), Ante (VA2BBW, Patrick (VA3CMD, and Jose (VA3PCJ), modified a few designs from Peter Parker (VK3YE) and came up with this person-portable ham radio station.  Interesting idea.  Be sure your back gets some support.

The perfect open-wire Dipole Antenna IMHO. Post #1454.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=zaSPcCwlb34.

One of the easiest and most effective HF antennas you can make is a properly designed half wavelength dipole mounted at least 1/2 wavelength above ground for your chosen band of operation.

Stan Gibilisco (W1GV) does an excellent job of explaining the theory, construction, and use of HF dipole antennas.  As Stan explains, this antenna is capable of multiband operation because of a balanced feed line used in conjunction with a balanced antenna "tuner" mounted at the end point of the balanced feed line.  A convenient length of 50 ohm coaxial cable (such as RG-8, RG-8X) run from the "tuner" to your rig completes the antenna system.  An automatic antenna "tuner" simplifies the tuning process.  Be sure each antenna element is cut for the lowest band of use.

Stan calls this HF antenna the "perfect open-wire dipole" because of its multi-frequency capabilities, inexpensive cost, and ease of assembly.

Ham Radio-Build your own L network antenna tuner. Post #1453.


If you can't see this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=EXD9rAOM_o4.

If you use a "long" or "random length" wire for your HF antenna, you'll probably need a simple antenna transmatch (i.e. "tuner") to reduce SWR and RFI caused by the mismatch between your antenna and your transceiver.

In this well-produced video, Kevin Loughin (KB9RLW) takes us step-by-step in the design, construction, and use of a simple L tuner for random length wire antennas.  This basic impedance transformer can be used at home and for field operations.  Views expressed in this video are those of KB9RLW.

How To Use An Antenna Analyzer-Basics. Post #1452.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=jOCG6bFGfuE.

An antenna analyzer is a useful addition to your ham shack. In this video from Randy Hall (K7AGE), we learn how to use the popular MFJ-259/269 Antenna Analyzer to check your antenna for SWR and Resonance.  This fairly inexpensive tool will come in handy the next time your build a new antenna or maintain your current "skyhook."  Randy does an excellent job of explaining how the MFJ-259/269 works and what you can expect to gain from using this device.  Views expressed in this video are those of Randy Hall (K7AGE).

7 MHz WSPR with a kite supported vertical antenna. Post #1451.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=SgN2FcMYL80.

Here's another great antenna idea from Australian radio amateur Peter Parker (VK3YE).  In this video, Peter tries a kite supported antenna to launch his WSPR signal.  WSPR can work with inefficient, short antennas, but really shines when you attach your rig to a half wavelength vertical antenna.  Peter says his 200mW signal was received in North America and the Canary Islands...great distance for a QRP signal.

Best First Amateur Ham Radio HF Antenna for New Operators. Post #1449.


If you can't see the video, please insert this title URL into your browser search box: https://youtu.be/wG3oS-2QrFE.  The views expressed in this video are those of "DX Commander" unless otherwise stated.

A nice, laid back antenna tutorial from "DX Commander" as he describes his first amateur radio antenna--a delta loop mounted 7 meters (22.96 ft) above ground.  This antenna produced great results for him during his first years as a licensed radio amateur.

In this video, "DX Commander" shows you how to design, build, use, and test a simple delta loop antenna, which can cover several amateur radio bands with a balanced feedline and an antenna "tuner."  Delta loops are easy to make, exhibit low noise on receive, and can be designed to be "stealthy" in crowded neighborhoods.
