Comment:

I ran across this fascinating article by Don Keith (N4KC) while I was searching for some new antenna ideas.  In this article, Don discusses five basic, easily-made antennas that will get you on the air quickly with a decent signal suitable for both DX and casual contacts.  According to Don, these simple, effective antennas are easy to build and use readily available materials.

Here are the top five get-on-the-air-quickly antennas:

The half-wave wire dipole.
The doublet with parallel feed lines.
The quarter-wavelength vertical with ground radial system.
The horizontal loop.
The original G5RV (a great antenna for the 40 and 20 meter bands).

Don does an excellent job of describing the theory, design, construction, and use of these simple antennas.  If you follow Don's suggestions, you'll be on the air with an effective, inexpensive antenna you built yourself .

Don closes his article with an upbeat message for those of us who may be afraid or our construction and design skills:

"So there they are. As mentioned, the main reason for this exercise is to give the new ham or someone who is returning to the hobby a bit of inspiration and some choices to consider for an antenna. And to urge them not to be too ambitious—ambitious to the point they never get around to putting anything up!
I think many of you will find a great deal of satisfaction in building your own aerial and then seeing how it works. There is certainly more satisfaction in that for many of us than there is in buying something already built and simply draping it over something in the backyard.
I do encourage you to play with your design. Try things. If they help, keep them. If they make your antenna a dummy load, toss it and start over. But most of all, have fun. And tell us about your experiences.
We are always interested in learning more."

Emergency Ham Antenna. Post #1265.


If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=iDHohc-w3Go.

If you need an emergency 2 meter, 1/2 wavelength antenna for your next portable operation, look no further than a piece of unused coaxial cable in your "junkbox." In this video from Aaron of "Prepping Ohio", we see how easy it is to convert some surplus cable into a simple, effective, and light weight antenna for 2 meters.  Add this antenna to your "Go-Kit" today.

How To Build A Delta Loop Antenna. Post#1263.


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

One of my favorite antennas is the Delta Loop. It has some gain, receives well, exhibits low noise, takes up little space, and is fairly inexpensive.  In this video, Hiram Vazquez discusses the theory, design, construction, and use of this versatile, easily-made antenna.  You can use balanced feeders in conjunction with a 4:1 balun and an antenna "tuner" to attain multi-band capability.

From ARRL President: Relief Efforts Need Your Help. Post #1261.

ARRL president appeals for volunteers to support hurricane relief efforts in Puerto Rico.

Source:  E-mails to ARRL members.

From:  Rick Roderick (K5UR), President, ARRL.

Accessed on 26 September 2017, 0515 UTC.

The Commonwealth of Puerto Rico and many smaller Caribbean Islands have been devastated by Hurricane Maria.  Although relief aid is arriving in this area, many smaller islands, including Puerto Rico, are facing dire shortages of water, electricity, medical aid, shelter, and communications.

ARRL President Rick Roderick (K6UR) has taken the rare step of appealing to the Amateur Radio Community, whether they be ARRL members or not, to support ongoing relief efforts in Puerto Rico.

On Monday, 25 September 2017, Roderick issued a mass e-mail appeal for help and included several areas where radio amateurs can best serve first responders.

Here's the full text of Roderick's message:
Monday, September 25, 2017 
Dear ARRL Member:
There are few times when I have needed to reach out directly to you for your help. This is one of those times.

The American Red Cross (ARC) has asked ARRL for assistance with relief efforts in Puerto Rico. In the nearly 75-year relationship between ARRL and ARC, this is the first time ARC has made a request for assistance on this scale. Hurricane Maria has devastated the island’s communications infrastructure. Without electricity and telephone, and with most of the cell sites out of service, millions of people are cut off from communicating. Shelters are unable to reach local emergency services and people cannot check on the welfare of their loved ones. The situation is dire.

How can you help?

1)    Volunteer. ARC needs up to 50 radio amateurs who can help record, enter, and submit disaster-survivor information into the ARC Safe and Well system. There are very specific requirements and qualifications needed for this deployment; for instance, familiarity with Winlink, an Amateur Radio license of General class or higher, and previous experience in disaster response.Deployment will be for up to 3 weeks (at ARC expense). If you would like to be considered for deployment, please complete the following online ARRL form, which asks for your qualifications and skills: Volunteer Deployment Form
2)    Donate to Ham Aid. ARRL’s Ham Aid program loans Amateur Radio equipment kits to established Amateur Radio Emergency Service (ARES®) groups and partner agencies during disaster response, in order to establish Amateur Radio communications support. Ham Aid is supported by donations from individuals and corporations – including many of our ham radio industry partners. ARRL has previously staged Ham Aid equipment in Texas, and in the last few weeks, we have supplied kits in Florida, the U.S. Virgin Islands, and Puerto Rico. Our supply of Ham Aid kits has been rapidly depleted. Your donation to Ham Aid will help us now. Your contributions to Ham Aid are 100% tax deductible. To make a donation online, go to www.arrl.org/arrl-donation-form and select “Ham Aid” from the ARRL donation form. To donate by mail, print a donation form, and mail it with your check payable to ARRL, noting “Ham Aid” on the memo line of your check; mail to ARRL, 225 Main Street, Newington, CT 06111 USA.

It has been four weeks since Hurricane Harvey made landfall in Texas. In little over a month, Hurricanes Harvey, Irma, and Maria have left paths of destruction and catastrophic flooding that will impact the lives of people throughout the southeast U.S. and Caribbean for years to come. Throughout these disasters, our trained ham radio volunteers, and especially those in coordinating roles, have helped us meet the requests of our partner agencies and organizations. To all ham radio operators who have been on alert, activated, deployed, or donated, THANK YOU. We are grateful for your service and for your generosity.

73
Rick Roderick, K5UR
ARRL President


Please help in any way you can.  The situation is "dire" and your support is needed.

N7EAA's 65 foot vertical for 160M. Post #1255.


If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=LXcInIk1fGo.

Here's a dual band top loaded vertical antenna that covers both the 160 meter and 80 meter amateur radio bands.  For this project, N7EAA used a MFJ pipe for $200, galvanized steel electrical fence wire, and inexpensive poly rope for guy supports.  You'll probably need some help assembling and erecting this antenna. Like all vertical antennas, you will need a good ground radial or counterpoise system.  In this video, N7EAA attaches his ground system to an aluminum plate at ground level.

Homebrew antenna , 10-40 meter loop antenna. Post #1253.


If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=3T1LOGahiwY.

Here's another HF loop antenna idea if you have some trees or tall supports in your backyard.  Marcus Schrader built this full-wavelength 40 meter loop (143 feet/43.59 meters) and suspended it 20 feet/6.09 meters above ground using a few trees in his back yard.  He uses a 4:1 balun along with a length of 450 ohm ladder line to feed the antenna.  Marcus uses this combination with an antenna "tuner" to cover 10 through 40 meters.  As you can see from the video, the antenna is fairly "stealthy".

Antenna simulator for small vertical monopoles. Post #1252.


Antenna simulator for small vertical monopoles.
(http://www.472khz.org/pages/tools/antenna-simulator.php).
Accessed on 16 September 2017, 2215 hrs, UTC.
Please click link to read the full article.

Comment:

Now that the FCC has established rules and regulations for the 630 and 2200 meter amateur radio bands, radio amateurs can now expand their contacts with frequencies below the standard broadcast band.

One of the prime concerns related to these bands, besides running low power and non-interference for existing services, is the type of antenna suitable for such low frequencies.

It's possible to design a relatively small vertical monopole antenna that will perform well in the rf "basement", thanks to this antenna simulator for 472 kHz.

Although this simple calculator isn't a replacement for software such as EZNEC, it will give you an indication on how this type of antenna will perform.  Just plug in the raw data about antenna type, antenna dimensions, and estimated ground losses, and you'll have a good, general idea of how much wire you must use for the 630 meter band.

Notice of the action appears in today's edition of the Federal
Register. Before using either band, stations must notify the
Utilities Technology Council (UTC), formerly the Utilities Telecom
Council, that they plan to do so, and if UTC does not respond within
30 days, they may commence operation.

The website to notify the UTC is,

Conference (WRC-12) implementation Report and Order (ET Docket
15-99), amending its Amateur Radio rules to - in the FCC's words -
"provide for frequency-sharing requirements in the 135.7-137.8 kHz
(2200-meter) and 472-479 kHz (630-meter) bands."

Section 97.313(g)(2) of those rules requires that, prior to starting
operation in either band, radio amateurs must notify UTC that they
intend operate by submitting their call signs, intended band(s) of
operation, and the coordinates of their antenna's fixed location.
The new rules do not permit any mobile operation.

"Amateur stations will be permitted to commence operations after a
30-day period, unless UTC notifies the station that its fixed
location is located within 1 kilometer of Power Line Carrier (PLC)
systems operating on the same or overlapping frequencies," the FCC
said. PLC systems are unlicensed. "This notification process will
ensure that amateur stations seeking to operate [on 630 or 2200
meters] are located beyond a minimum separation distance from PLC
transmission lines, which will help ensure the compatibility and
coexistence of amateur and PLC operations, and promote shared use of
the bands."

The FCC announced that it is making effective immediately the Part
97 rule amendments, Part 97.3, 97.15(c), 97.301(b) through (d),
97.303(g), 97.305(c), and 97.313(k) and (l), which do not require
OMB approval.

K1GMM 6 METER 3 ELEMENT QUAD BUILD 9.4 DBi. Post #1249.


If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=i6xH-s1rpiM.

Even in times of poor propagation, the 6 meter amateur radio band can still produce interesting contacts--often at surprising distances.  In this video from K1GMM, we learn how to build a 3-element 6 meter yagi that can deliver approximately 9.4 dBi gain.  According to K1GMM, all of the parts can be obtained for around $60 from a well-stocked home improvement outlet or hardware store.  The antenna can be broken down easily for portable or emergency operations.

Tuning a CB Whip for use on the 10 Meter Ham Band. Post #1246.


If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=m3Oho0Icbis.

If you have a few old CB antennas around your shack, why not covert some of them into 10 meter mobile or home station use?  My current 10 meter vertical antenna is a cut down 108-inch/274.32 cm steel CB whip I bought years ago at Radio Shack.  Used as a ground plane antenna, this converted CB antenna does a good job on 10 meters when the band opens.

In this video by Tony (KD8RTT) and his brother Andy (KK4LWR), we see a simple way of modifying a CB whip antenna for use on the 10 meter Amateur Radio Band.  Their MFJ HF/VHF SWR analyzer helps in the trimming process.

Don't let that old CB antenna go to waste.  Convert it now into a simple, effective mobile or portable antenna.

HF Multi-Band Dipole. Post #1245.


HF Multi-Band Dipole
(http://hamuniverse.com/multidipole.html).
Accessed on 10 September 2017, 0120 hrs, UTC.
Please enter title URL into your browser search box to view the full article and photographs.

Comment:

This variant of the popular "Fan Dipole" antenna was based on work done by the Stanford Research Institute (SRI).  The aim of the SRI project was to develop a multi-band HF dipole antenna that would work without any need for cut and prune techniques.

The article provides all of the critical measurements, construction techniques, and materials needed to make a versatile, easy-to-use multi-band HF antenna covering the 80, 40, 20, and 10 meter bands without the use of an antenna "tuner."

Ham Radio - The simple coax cable emergency prepper antenna. Post #1241.


If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=tafy51yUzQo.

It may be wise to make several versions of this simple, inexpensive antenna for portable or emergency operations.  Kevin Loughin (KB9RLW) does an excellent job of creating an emergency antenna from coaxial cable.  The antenna is easy to build and uses a minimum of tools.  The antenna can be designed for your favorite amateur radio bands and stored in your vehicle or shack when you need to get on the air quickly.

Antennas in the Attic: Ham Nation 215. Post #1239.


If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=gFW-dre0OrQ.

This excellent video with Gordon West (WB6NOA) comes from the Ham Nation program, episode 215.  In this video, Gordon shows how radio amateurs remain active by placing a variety of antennas in their attics.  Sometimes, there are no other alternatives because of deed-restricted housing (HOAs and CC&Rs). A few of these compromise antennas work quite well, delivering hours of operating time to antenna-limited areas.  Hopefully, some of these suggestions will help you get and stay on the air.

Build your own 110 foot multi band dipole home brew ham radio HF antenna. Post #1238.


. If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=5B0wCP2Tsdw.

Here's a simple, efficient, and inexpensive HF dipole antenna that covers 80 meters to 6 meters.  The key to multiband operation is the use of 300 ohm twin lead as a feeder and a 1:1 ATU balun.  You can also use 450 ohm ladder line or home made balanced line into a 1:4 current balun and then connecting the antenna feed line and balun to an antenna "tuner" with a short length of 50 ohm coaxial cable.  W5XJ provides a list of easily obtainable materials for this versatile antenna.  If you have only one tall support, you can configure the antenna as a dipole "sloper" antenna.

CB antenna to ham radio. Post #1237.


If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=oYg9jbdjTIw.

Excellent, well-paced video from "Musings" showing us one way to convert a 5/8 wave CB antenna for ham radio use.  Depending on your interests, this video can help you transform an old 11 meter (CB) antenna into an effective vertical antenna for 20, 15, or 10 meters with just a few shop tools and a little imagination. I've converted a few 108-inch/274.32 cm CB whip antennas (from Radio Shack) into usable 10 meter vertical antennas without much difficulty. While this video has a bit of a learning curve, it shouldn't be too hard to copy the procedures shown and build your own, inexpensive HF vertical antenna from unused or discarded CB antennas.
