Every vertical antenna needs a ground radial or a counterpoise system to realize maximum efficiency and reduced SWR.  If you can't lay in a ground radial system, then a counterpoise system consisting of 1/4 wave length wires running parallel to the ground, suspended over the ground under the vertical antenna will insure that SWR is tamed and that your vertical antenna is radiating more efficiently.  In this video, the antenna in question is a tri-band 6 meter, 2 meter, and 70 cm vertical with added counterpoise wires.  An interesting project that you can complete in just a few hours.

I've always favored "homebrewed" wire antennas for the annual ARRL Field Day, which occurs on the third full weekend of June.  Whether I've opted to run my portable station in my backyard (because of work requirements) or chosen to help with the Big Island Amateur Radio Club Field Day site, I always have a spare DIY antenna in my van or under my operating desk.  Along with my portable multiband HF antenna, I also carry a "go-kit" with a HF transceiver, solar panels, deep cycle marine battery, an antenna "tuner", spare feed lines (usually 450 ohm ladder line), and a variety of 1:4 and 1:1 current baluns.  I've tried a few of the antennas described in this article and found them to be reasonably simple, portable, and easily rep…

Bob Hajdak (N8QE) wraps up this 8 part series on the ARRL Field Day with one of the best reasons to join your fellow radio amateurs "in the field"--"It's blast!"  Granted, Field Day is supposed to be a test of our emergency communications preparedness, and it is for the most part. But there's nothing in the ARRL Field Day rules that outlaws fun, friendship, and, occasionally, excellent food prepared over a campfire or portable butane stove.  Even if you can't join a club in the field, take your station outside, erect a temporary antenna, position your solar panels, hook up a deep cycle marine battery, and get ready for a radio adventure. Enjoy the upcoming ARRL Field Day!

Thanks to DXEngineering for an enjoyable and enlightening video series on Field Day.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=jEO9JSRXeZI.

One of the joys of Amateur/Ham Radio is the ability to experiment with antennas and various pieces of equipment.  We can learn a lot about our hobby by just getting down to "the nuts and bolts" of designing, building, and testing our homemade accessories and repairing our equipment.  This is particularly true of antennas, where unconventional designs often work very well.

In this video, Kevin Loughin (KB9RLW) continues his series on magnetic loop antennas by showing and testing some of his designs built on his workbench.  Most of Kevin's projects use locally available materials from neighboring home improvement and hardware stores.  If you're in an experimental mood, why not try some of Kevin's magnetic loop antenna designs?  These simple projects should be of particular interest to those operating in deed-restricted properties…

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=JWZZlpHJKT8.

A nice, simple, inexpensive 160 Meter Inverted L Antenna from Bob Holowenko.  Bob used 1000 ft/304.87 meters of 14 AWG (7 strand) wire, some rope, a simple ground radial system, and a few things found in his ham shack to build this winter time antenna for "The Gentlemen's Band."

According to Bob, he used 127 ft/38.71 meters of wire for the vertical section of the antenna, six, 127 ft/39.71 meters of wire for the ground radials, and "a pile of random wire, including a fence" to complete his antenna system.  This video may give you a few ideas for the upcoming ARRL Field Day.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=nnN0NVGqtKQ.

Those of us who use vertical antennas for our ham radio stations know the importance of having a good ground radial system.  Ground radials supply "the missing half" of our quarter wavelength vertical antennas and make those antennas more efficient.

Installing ground radials can be quite a task, especially if you want more than the bare minimum ground radial system.  In this video, Rich Rodgers uses an electric edger to dig  fairly straight groves to lay his radial wires.  You may want to keep the wires flat with plastic lawn staples available at many hardware stores.  This seems to be a good way to install ground radials.

Do you need a cheap, easily assembled, mostly "stealthy", and completely portable 2 meter antenna?
If you do, then this article from Don (N4UJM) is worth reading.

In his post, Don describes 3 simple 2 meter antennas that can be made from locally available materials:

The ultra simple "wire" version that can be suspended from a convenient support.  This antenna can be used indoors or outdoors.

A table top 2 meter antenna using a dowel or other simple, weighted support.

And a simple beam or yagi antenna incorporating the above designs. 

Don also offers some construction and operating tips for these antennas.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=cQfj9879K_c.

Here's an ultra simple, inexpensive dipole antenna that you can build in a few hours.  Using locally available materials, Bob Plank (KK4DIV) shows us how to design, build, and use a dipole antenna which covers the 40,20, 17, 15, and 10 meter Amateur Radio bands.  Calculators for element lengths can be found online.  Bob used an antenna design program he downloaded from http://hamuniverse.com.  For a bit more flexibility, you may want to substitute 450 ohm ladder line for Bob's coaxial cable feed.  By using ladder line and an antenna transmatch (i.e. "tuner") coupled with a 1:1 or 1:4 current balun, you can get coverage from 80 though 10 meters.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=ofmUK8o7Jxg.

Nicely done video tutorial from "rcobo 101" (AC2RJ) on how to design, build, and use a multiband HF portable vertical antenna.  The material list is short:  35 feet/10.67 meters of speaker wire wrapped as a helix around a 20 foot/16.097 meters fiberglass pole, a sturdy tripod, an antenna transmatch (i.e. "tuner"), a basic ground radial system, a CW key, portable power, and a suitable HF transceiver. 

My current vertical at my home station is a variation of this design using 65 feet/19.81 meters of speaker wire mounted as a vertical helix on a 33 foot/10.06 meters telescoping fiberglass pole.  I use 450 ohm ladder line to feed the antenna, which is, in turn, connected to a 4:1 current balun/coax cable combination connected to my trusty Drake MN-4 "tuner."  A modest set of 8 quarter wave radials cut for 7.088 MHz comple…

Rebuild MFJ-1622 Apartment Antenna for Ham Radio HF. Post #1507.

Image
If you can't see the video, please enter this title URL into your browser search box: https://www.youtube.com/watch?v=hSOt9KRooek.

The MFJ-1622 Apartment Antenna has been around for several years, and can be modified to improve its performance on any Amateur Radio band from 40 meters through 2 meters.  The antenna is a good choice for those of use operating in deed-restricted properties governed by HOAs and CC&Rs.

In this well-thought out tutorial, "North Carolina Prepper" shows us how to improve the basic design of the MFJ-1622 so it performs at a higher level.

I have one of these antennas for portable and emergency use, and  find the antenna works a lot better if you replace the coax feed line with RG-8X and attach a radial wire for each band of use. Of course, changing the tap on the coil would be the first step in upgrading this antenna, but using better coax and using a few radial wires wouldn't hurt, either.  The video does an excellent job of making this…

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=kojw_-z39z0.

Quad antennas do very well on VHF and UHF bands.  However, the survivability of the antenna corners is limited in areas where severe wind or weather prevails. In this video from Dave Tadlock (KG0ZZ), we see how simple kite or arrow nocks can strengthen the corners of a 2 meter quad and add more life to this versatile antenna.  Dave has produced a series of video tutorials on quads for 2 m and 70 cm applications.  Each video provides a step-by-step process you can follow to make an effective and sturdy antenna for both home and portable use.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=hK0KX0YcvH0.

Do you want better performance from your HT or other FM gear? Then disconnect the stock "Rubber Ducky" antenna that came with your HT and use this design from "electronicsNmore" instead.  All you need to make this vertical sleeve 1/2 wave coax antenna is some 50 ohm coaxial cable with copper shielding, a small diameter brass or copper tube,solder and rosin flux, a bit of heat-shrink tubing, and a SWR meter to help you trim the length of the antenna.

This project is perfect for clubs, portable and field operations, and casual use.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=wu6x37O1O-k.

Most radio amateurs who participate in the annual ARRL Field Day communications exercise rely on some form of alternate energy to keep their stations on the air.  One of the popular choices for emergency power backup is solar power in the form of panels mounted near your Amateur Radio station.

In this video, Julian (OH8STN) shows us how to set up a tower-mounted solar panel system, including charge controllers and a "repurposed" battery for providing power during a "grid down" emergency.

Julian believes emergency communications should not only be designed for field use but also for your home station.  One never knows when commercial power mains may be rendered inoperable.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=2Mgd06UAHbU.

The ARRL Field Day is coming to the last full weekend of June (23-24 June 2018).  Radio amateurs from around the world participate in this emergency communications exercise to sharpen their technical and antenna skills.  Field Day is also one of the biggest contests of the year, with contacts ranging from amateur satellites to the most exotic digital modes.  And, yes, the act of getting out in the outdoors and operating with solar power, homemade antennas, and low-powered rigs is a lot of fun.

As this video from "motoforlyfe" explains, you don't have to join a club to participate in this annual summer event.  You can operate from your home using your backyard as your playing field.  I've operated from my home several times when work requirements precluded travel to my club's field day site.  This video does an excellent job of …

Magnetic Loop Transmitting Antenna. Post #1494.

If you can't see the video, please insert this title URL into your browser searchbox: https://www.youtube.com/watch?v=mMCKOHyfeJ0.

Here's an interesting magnetic loop antenna from Peter Parker (VK3YE) when he first started experimenting with this type of HF antenna.  According to Peter, this "compact magnetic loop antenna (is) capable of operation on all amateur radio bands between 160-10 meters."  Although the efficiency is quite low, Peter was able to make solid contacts from his backyard with this experimental transmitting loop.

Peter says the feed line "connects directly to the copper tube which has a tapping point for the coax inner...other builders use a second smaller loop inside."

If you have restricted space for a multiband HF antenna, you may want to try Peter's antenna.

If you can't join your Amateur Radio Club for this year's ARRL Field Day (23-24 June 2018), why not go solo and set up camping-based single station for the event. In this video "Outdoors On The Air" mounted a small, one-man Field Day station in his back yard for the 2014 event.  He did rather well, making 135 contacts on 40, 20, and 15 meters with a few end-fed wire antennas. There are special categories for single-operator stations, including mobile, battery-powered, or commercially powered arrangements.  Be sure to bring plenty of coffee and snacks--it will be a long, intense night.

Another way to get on 160 meters on a medium-sized urban lot is to design and build a simple 160 Meter Inverted L Antenna.  In this video from Bob Holowenko, we see how he built an effective 160 Meter Inverted L Antenna from 127 feet/38.719 meters of wire, six-127 feet/39.719 meters radials, and "a pile of random wire, including a fence."  You may find Bob's antenna a good start for your 160 meter antenna.

Ham Radio 40/80/160 Meter Inverted V Dipole Antenna. Post #1491.

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

Dave Tadlock (KG0ZZ) does an excellent job of taking us through the theory, design, construction, and use of a multiband V dipole antenna covering the 40, 80, and 160 meter amateur radio bands.  Like the previous post by Peter Parker (VK3YE), Dave takes a 40 meter dipole or inverted V and adds more bands by means of loading coils, carefully chosen element lengths, and optimal height to give us multiband capabilities without the use of an antenna transmatch (i.e. "tuner").

While there is some loss of efficiency and bandwidth, this antenna brings you the opportunity of operating on lower HF bands with just one antenna structure.  Dave adds that this antenna can fit in most urban lots with a little pre-planning.  A good, overall HF antenna for this age of marginal propagation.

Adding 80 metres to a 40 metre dipole. Post #1490.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v-4kRz6fPFKY.

Here's an easy, inexpensive way to add the 80 meter amateur radio band to your existing 40 meter dipole antenna.  With the solar cycle heading towards the bottom, lower HF frequencies, such as 80 and 160 meters, become dependable, viable bands for radio amateurs.

In this video, Peter Parker (VK3YE) uses end loading coils to make a 7 MHz dipole operate on 3.5 MHz.  If you're willing to sacrifice some efficiency and bandwidth, this antenna modification will get you on the air quickly from your home QTH.

Here are some observations from Peter regarding overall design and construction suggestions for this antenna transformation:

"A 7 MHz dipole made to operate on 3.5 MHz by adding end loading coils. It won't be as efficient as a full sized 80m dipole and the bandwidth will be narrow. However it will get you on the air from a small yard.…
