Comment:

Erecting a high-performance antenna in a deed-restricted property (HOA/CC&R) can present some difficult challenges for radio amateurs.  Dave Land  (KD5FX) explores this issue in depth and comes up with several antenna designs that could be used in such areas.  Each antenna is fully described with both drawings and photos, so you can easily build each design quickly and efficiently.  Overall, Dave has done an excellent job of assembling antennas that can be used in limited spaces.

Here are the major antennas described in Dave's article:

The basic dipole, multiband dipoles, random length multiband antennas, verticals, flag pole verticals, inverted V, mobile antennas adapted for backyard use, the fencetenna, G5RV, W5GI Mystery Antenna, Buddipole antennas, inverted L, Hamstick antennas, Isotrons, no radial verticals, vertical dipoles, Ventennas for VHF/UHF, and remote antenna "tuners."

Hopefully, you can use some of Dave's ideas to get you on the air in your controlled environment.

An amateur radio 2 meter/70 cm antenna made from an old coffee can. Post #1539.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=c2AyfBMRztw.

Common household objects can often be used as antenna elements.  Such is the case with this excellent video tutorial from Dave Tadlock (KG0ZZ).  Dave shows how an old coffee can can be repurposed as a home made 2 meter/70 cm antenna.  All you need is a vertical element cut to the correct length and some kind of metal ground plane or counterpoise to complete the antenna.  The shield of your coaxial feed line might serve this purpose.  A clearly explained, step-by-step procedure that will have you on the air with a fully functional 2 meter/70 cm antenna in a short time.  Depending on what you have in your ham shack, this project could cost you very little.

40M Delta loop antenna (horizontal) set up, Part 2.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=zFbJ7xym_Dg.

In part 2 of this video tutorial, "DENMONKEY" completes the initial design, construction, and configuration of his 40 meter delta loop antenna.  He then raises the antenna and makes a few minor adjustments before the testing cycle begins.  The delta loop antenna is a good choice for radio amateurs who can only erect one HF antenna on their property.

40M Delta loop antenna (horizontal), Part 1, Post 1537.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=gWIsU1Sy3NY.

HF Delta Loop Antennas are quiet, versatile, and cost effective antennas for radio amateurs who have room for only one HF antenna.  In this video, "DENMONKEY" takes us step-by-step through the design, construction, set up, running support ropes, and raising of the antenna.  In this case, the antenna is fed at the apex of the support mast using a 4:1 balun connected to convenient length of 50 ohm coaxial cable.  Six to eight turns of the coaxial feed line serve as an RF choke.  In this configuration, the Delta Loop is vertically polarized.  Multiband operation is possible by using a balanced feed line into a balanced antenna "tuner" or into a current balun, coax, antenna "tuner" combination.

In Part 2, DENMONKEY tests the antenna and makes a few adjustments.

Tape Measure Yagi Beam Antenna for 2 meters. Post #1536.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=BmHoQrDfw-0

Michael Martens (KB9VBR) has done an excellent job in explaining how to build a simple, inexpensive 3-element yagi beam antenna for the 2 meter Amateur Radio band.  Michael used commonly available materials for this antenna, including some PVC pipe, steel tape measures, electrical tape, and some coaxial cable from his shack.  Michael's demonstration is quick, to-the-point, and easily followed. This antenna can be used for fox hunts (RDF tests), portable operations, and even for public service events which require a directional antenna.

How to Make an Amateur Ham radio Stealth Wire Mast Support. Post #1535.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=4KQEQJ5qeuw.

Another great and often humorous approach to supporting stealth wire antennas from Callum McCormick (M0MCX).  In this video, Callum shows how aluminum scaffold tubes slip inside sail board/wind surfing masts to make cheap, economic, and structurally sound supports for hidden or stealth antennas.  You could also use telescoping fiberglass masts, PVC pipe, and even bamboo to fashion antenna masts for hidden antennas.  Callum offers many suggestions on how you can raise and support stealth antennas, especially for radio amateurs who have no trees on their property.

How a simple counterpoise system can lower your SWR. Post #1534.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=SwhlSa8CUCk .

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.

Comment:

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 repaired should disaster strike.

Thanks to http://www.dxzone.com and a few suggestions from the Amateur Radio Community, here are "13 Cool Ideas for Your Field Day Antenna."  May you make many contacts over the weekend.

8 Things We Love About Field Day, Part 8 of 8, Post #1532.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=E64hCBmA2O8&feature=youtu.be.

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.

Ham Radio Antennas-Magnetic Loop experiments. Post #1524.


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 controlled by HOAs and CC&Rs.

Another great video tutorial from Callum (M0MCX), the "DX Commander."  In this video, Callum describes how he made his first Inverted L Antenna when he entered the summer IOTA (Islands On The Air) contest.  Callum says his design for the 80 meter Amateur Radio band had a "small footprint" and was good for both DX and local contacts.

If you choose to build an Inverted L HF Antenna, be sure to have a good ground radial system to raise efficiency and reduce RFI in your shack.

160 Meter Inverted L Antenna. Post #1520.


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.

Here's another idea for the upcoming ARRL Field Day from Carl (2E0EZT).  In this video, Carl takes to the field with camping gear, portable ham equipment, two major antennas, and a firm determination to succeed.  Carl was able to make some interesting contacts with his Yaesu FT-817, an Icom 706 mk1, a wire dipole, and the MP1 "super antenna." It doesn't take much to assemble a simple, effective portable ham radio station.  But, most of all, try to have some fun while snagging those elusive contacts.

How To Install Ham Antenna Ground Radials. Post #1517.


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.

Installing Your Ham Radio in Your Vehicle. Post #1516.


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

Nicely done video by Eric of "Ham Radio Concepts."  Although every vehicle will be different, Eric shows us some of the common solutions to most mobile installation problems.  In this video, Eric concentrates on the installation of VHF/UHF transceivers and mobile antennas. 

Please note the importance of grounding straps, proper fusing of power leads to the vehicle battery, and proper antenna placement.  Just take your time and do the installation correctly  Also be aware that some magnetic mount antennas may not work on car bodies made of aluminum and fiberglass.

QRP portable in the John Moyle Field Day 2018. Post #1515.


If you can't see the video, please enter this title URL into your browser search box: https://www.youtube.com/watch?v=E4kBDWILTNE.

While many U.S. and Canadian radio amateurs are preparing for the ARRL Field Day on 23-24 June 2018, our friends in Australia got an early start with the John Moyle QRP portable Field Day event earlier this year.

In this video, Peter Parker (VK3YE) takes his Yaesu-817 QRP HF/VHF transceiver to a nearby beach, assembles a simple end-fed wire, adjusts his ATU (antenna tuning unit), and proceeds to collect some interesting contacts on the 80, 40, and 20 meter Amateur Radio bands.  The set up is ultra simple and entirely portable.  Peter located his antenna near the water's edge and got some excellent propagation for his low-powered signal.

An ATU for end fed aerials. Post #1514.


If you can't see the video, please insert this title URL into your browser search box://https://www.youtube.com/watch?v=o43sAF4HwJs.

Here's another expertly done video tutorial from Ray of the UK-based "Radio Workshop."  In this video, Ray show us how to build a simple, inexpensive L-match ATU (Antenna Tuning Unit) for the HF shortwave and Amateur Radio bands.  The ATU can be used with end fed "aerials", including inverted L antennas.  A definite must have accessory for radio amateurs using random length or inverted L antennas.  Don't forget to connect your antenna system to a good radial or counterpoise system.

Comment:

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.

Building a Multi-Band Dipole. Post #1512.


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.

Tuning the 40/80 meter Inverted V Dipole Antenna, Post #1511.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=IKuLDnwuy8M.

Inverted V Dipole Antennas are simple, inexpensive, portable, and capable of multiband operations using a variety of options.  In this video, Dave Tadlock (KG0ZZ) uses homebrew coils to convert his inverted V antenna into a dual-band, 40/80 meter antenna.  The video offers valuable suggestions on adjusting the loading coils for optimum efficiency on both 40 and 80 meters.  This coil-loaded 40/80 meter inverted V would make an excellent HF antenna for the upcoming ARRL Field Day, especially now that propagation is favoring 160, 80, and 40 meters.
