Building A Ham Radio Repeater Tower. Post 1760.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=1T_1K1eMCkc.

Designing, building, and installing an Amateur/Ham Radio tower is serious business.  In this video, Chris travels to the mountains of Westcliffe, Colorado to help his dad build a ham radio repeater tower.  Chris experiences high winds and a minor cable issue during the installation of the 30-foot/9.146 meter tower. 

Although the process seams simple and fairly safe, don't assume all steps will go smoothly.  Fortunately for Chris and his dad, the installation was solid and presented only a few minor problems.  If you doubt your ability to install a tower, please consult a professional rigger or engineer.

Pats Ham Shack - HOA Stealth. Post 1759.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=EWvgAxkoh2s.

If you're facing severe antenna limitations imposed by deed-restricted housing (HOA/CC&R), you may find this "stealthy" antenna system from Patrick Dortch worth your time.

Patrick has placed all of his antenna feed lines in "secret" underground tunnels which lead to a distant group of trees concealing his two antennas.  Nothing suspicious rests above ground for peering eyes to see.  About the only thing I would add are locks and vermin protection to his feed line boxes.  A beautiful, but somewhat costly answer to the "antenna police".

Chameleon Emcomm III Portable Antenna (Winter Field Day) - Ham Radio Q&A. Post 1758.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=H5AHKAz3Zh4

What better way to test a new HF portable antenna than to subject it to winter conditions?  In this video from Michael Martens (KB9VBR), we get an excellent idea of how this new Chameleon Emcomm Portable Antenna works in an actual Winter Field Day environment. 

According to Michael, the new antenna is "especially designed for short and long range" applications as well as for "manpack HF communications."  Michael adds that the antenna "is ideal for hiking, backpacking, and both tent and Recreational Vehicle (RV) camping."

The video is useful, informative, and easy to understand.

Ham Radio Roof Vent Antenna For 2 Meters. Post 1757.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=8KVSoM6w73o

Larry, the "RadioHamGuy", offers a simple, elegant, and functional way to establish reliable 2 meter communication from your home.  Larry uses a surplus 5/8 wavelength magnetic mobile mount antenna, a fairly empty attic, and a few cables to make a "stealthy" 2 meter antenna for his garage ham radio shack.  About the only thing I would add to this excellent arrangement is a "drip loop" for his coaxial feed line before it enters the roof vent.  As antenna experimenter Kevin Loughin (KB9RLW) points out, Larry's 2 meter antenna "can be used on 6 meters as a 1/4 wave antenna with a 1.3:1 SWR on the lower end of the band." So, using Larry's antenna set up, you can get two antennas for the price of one.

Fan dipole, or multi-band dipole, antenna in my attic for my ham radio h...


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=ju5HNzsO1Ns.

Ron C has put together an outstanding HF multi-band dipole in his attic.  Like many of our fellow radio amateurs, Ron faces antenna restrictions imposed by HOAs and CC&Rs.  Ron shows us how to use available space to design, build, test, and use an antenna that remains "stealthy" and effective.  All you need is a single feed line, several single band dipoles connected to a center connector, and perhaps an antenna transmatch (i.e. "tuner") to get on the air without raising the suspicions of neighbors.  "Fan Dipoles" are suitable for portable operations such as Field Days and emergency communications exercises.  If you carefully trim each single band dipole and keep the elements separated by a few inches, an antenna "tuner" may not be necessary.  A "Fan Dipole" may be the answer to those of us who live in deed-restricted housing.

7 and 28 MHz HF pedestrian mobile with 6m wire antenna


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=vqJrm0OffiM

Australian radio amateur Peter Parker (VK3YE) always has something new in the field of simple, homemade antennas that actually work and produce contacts.

In this video, Peter ventures into the realm of pedestrian mobile, something I've never tried, but would like to experience in the months ahead.  Peter's pedestrian mobile station consists of a telescoping fiberglass pole, 6 meters (19.68 feet) of wire, a simple L tuner, an a trusty Yaesu FT-817.  The antenna is  1/8 wavelength on 7 MHz and 5/8 wavelength on 28 MHz.  The small homemade L tuner tames the SWR and permits easy contacts without damaging the QRP rig.  Make one of these antennas for portable and emergency use.  The antenna system is fairly small and should fit into your vehicle with few problems.

Doublet aerial for HF amateur ham radio short wave bands. Post 1754.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=8ZmyvtMvEGY

An effective, simple, and inexpensive multiband HF dipole antenna is as close as your "junk box" and the local building supply outlet. If you can find some 300 ohm television ribbon feed line, a 4:1 current balun, and an extra antenna transmatch (i.e. "tuner"), you'll be able to make a classic "doublet" antenna that will serve you well for many years.

In this video, Ray of the "Radio Workshop" show us how to build an ultra-simple doublet antenna with commonly available parts.  The doublet is suitable for both home and field operations.  Try one--you won't be disappointed.

ARRL abandons congressional efforts to pass the Amateur Radio Parity Act. Post 1753

ARRL drops efforts to pass the Amateur Radio Parity Act.

Accessed on 25 January 2019, 0304 UTC, Post 1753.

Source:  http://www.arrl.org/arrlletter?issue=2019-01-21.

Editor:  Rick Lindquist (WW1ME).

As the old saying goes:  "Close, but no cigar."  The ARRL Board of Directors has decided to abandon legislative efforts to save the "Amateur Radio Parity Act".  The legislative package was aimed at relieving some of the antenna restrictions found in deed-restricted properties (HOAs and CC&Rs).  Over the past few years, the "Amateur Radio Parity Act" has come close to passage, but was stopped cold when the U.S. Congress rejected the measure.

Rather than try another congressional battle, the ARRL has decided to appeal directly to the FCC (Federal Communications Commission) for antenna relief.

Here's the official position of the ARRL from the 24 January 2019 issue of "The ARRL Letter":

"ARRL Board of Directors Issues Statement on Amateur Radio Parity Act
At its annual meeting January 18 - 19, the ARRL Board of Directors decided that the organization needs to "review, re-examine, and reappraise ARRL's regulatory and legislative policy with regard to private land use restrictions."
In order to effectively undertake such a review, the Board adopted a resolution to withdraw its December 18 Petition for Rule Making to the FCC, which sought to amend the Part 97 Amateur Service rules to incorporate the provisions of the Amateur Radio Parity Act (ARPA), without prejudice to refiling. The resolution also is asking members of Congress who had refiled legislation to enact the Amateur Radio Parity Act (ARPA) to refrain from seeking to advance that legislation pending further input from ARRL.
Board members noted that ARRL has been pursuing adoption of the ARPA for the past several years, and that objective has not yet been achieved. While everyone understands that getting Congressional approval on any matter can be a lengthy process, the difficulties getting the ARPA approved has been a source of frustration to the organization and its members. A majority of the Board now believes that there is a need to reassess the organization's approach to this issue.
The Board wants to make clear to its members, and to those whose policies and conduct prevent or impair the right of US Amateur Radio operators to operate from their homes, that this pause is not, and should not be interpreted as an abandonment of its efforts to obtain relief from private land-use restrictions. The Board noted that its intent is "to renew, continue and strengthen the ARRL's effort to achieve relief from such restrictions." This action represents a chance to get the best product possible for all US Amateur Radio operators.
The Board expressed its sincere appreciation to the thousands of ARRL members who took the time to contact their representatives in Congress to urge them to support the Amateur Radio Parity Act. The Board also offered its thanks to those members of Congress who have consistently and continuously supported the rights of US Amateur Radio operators."

ARRL Field Day Safety - Ham Radio Q&A. Post 1752.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=vXIUqr3tMpU

One of the great experiences facing radio amateurs is the annual ARRL Field Day, usually held on the last full weekend of June.  Field Day is part contest, part emergency preparedness, and mostly fun.  Approximately 40,000 hams throughout North America will "head to the field" to set up operating sites, erect portable antennas, power emergency rigs, and divide time between swatting pesky insects and making contacts.

In this video by Michael Martens (KB9VBR), we learn that communicating "in the wild can bring out a myriad of challenges, the largest, notwithstanding, is operator and station safety."  Michael takes us step-by-step through the basic safety and operating procedures that will protect your life while you make contacts with your fellow radio amateurs.  Pay particular attention to his comments on generators, grounds, antenna integrity, and site security.  It's not too early to prepare for one of the largest amateur radio events.

Antenna Types and Terminology: AD#30. Post 1750.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=U0WB-3UToLg

Here's another outstanding video tutorial from Dave Casler (KE0OG).  This time, Dave discusses the theory and terminology of antennas used for amateur radio communications.  The video does and excellent job of  explaining the workings of several antenna types, including dipoles, inverted Vees, verticals, loops, and quads.  His illustrations and photos are clear and easily understood.  This video would make an excellent program for your next club meeting or for an upcoming amateur radio license class.

Folded Dipole Fed With TV Cable. Post 1749.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=ar9F2sck0iI

Here's a quick and easy Folded Dipole Antenna made from locally available materials.  According to Stan Gibilisco (W1GV), all you need is a half wavelength of TV Ribbon (300 ohms) or Ladder Line (450 ohms), a 4:1 current balun, a length of 75 ohm TV Cable (such as RG-6), some F to SO-239 adapters, and an antenna transmatch (i.e. "tuner") to keep SWR below 1.5 to 1 across the band of choice.  Stan says the slight mismatch between 50 ohm and 75 ohm cables can be handled by most modern transceivers without much loss of power. That mismatch is in the neighborhood of 1.5 to 1 without a "tuner".  With Folded Dipole Antennas, I've always used a "tuner" to be on the safe side.

So, if you have some TV Ribbon and a length of RG-6 TV cable in your junk box, why not build a folded dipole antenna?  With a little luck, you can build a broad-banded HF antenna at almost no cost.

Stealth Vertical Full Wave Loop Antenna Ham Radio. Post 1748.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=pqnpmj8hxtQ.

Rich Rodgers has come up with another way of using a stealth antenna in his deed-restricted property.  In this video, Rich shows how he positioned a vertical full wave loop antenna between some elevated bird houses to disguise his HF antenna.  According to Rich the antenna SWR is acceptable with an inline antenna transmatch (i.e. "tuner").  You could also use a 4:1 current balun between your antenna "tuner" and antenna feed to reduce SWR even further.

I've used several full wave loop antennas on 40 meters using balanced feed line and a balun-"tuner" combination to give me multiband coverage.  Rich's project is simple and should get you on the with air minimum problems.  Just make sure HOA "enforcers" don't examine the bird houses too closely.  One could always use a telescoping fiberglass mast to support a sloping delta loop. Just raise the loop when you want to operate, and lower the mast and loop when you're done.

Ham Radio - My 630 meter magloop. An overview. Post 1746.


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

Now that radio amateurs have gained limited access to the 630 meter and 2200 meter bands, it may be time to build some simple antennas to make contacts on those frequencies (472 kHz and 137 kHz).  Working these bands presents a few challenges, including the lack of ready-made equipment and antennas to make contacts, the relative low efficiency of antennas that are available, and the severe power restrictions imposed by the FCC on those bands (about 1 watt ERP).

Despite these limitations, hams across North America are making some fascinating contacts, often with homebrew equipment and antennas.  In this well-made video from Kevin Loughin (KB9RLW), we learn how to make a simple, inexpensive, and fun-to-use magnetic loop antenna for the 630 meter band.  Kevin says his design works and is eagerly pursuing more contacts on the low frequencies.

Australian ham Peter Parker (VK3YE) shows some of the capabilities of his homebrew "Half Square Antenna" for 10 MHz and above.  A half square antenna is a wire antenna with two vertical radiators fed in phase.  One vertical element (1/4 wave length) is fed at the top where it's attached to a SO-239 connector. The other side of the SO-239 is attached to a horizontal half wave phasing line, then connected to another vertical element (1/4 wave length) aiming at the ground. 

Thanks to some help from a nearby Australian beach, Peter was able to make contact with EA8YT/M on 10 MHz, another station on 14 MHz, and finally an EA station on 7 MHz.  As Peter suggests, you can set up your half square antenna with the help of two telescoping fiberglass fishing rods (squid poles)

Building a 10 meter J Pole Antenna. Post 1739.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=KWt6eaxSK04

Do you want a simple, effective, low visual impact antenna for your 10 meter operations?  If you do, then this video tutorial by machinist Don Nichols (KV4PH) will guide you in the right direction.  Don presented this program to members of the Vienna Wireless Society Radio Club on 12 August 2016.  The finished project is almost a work of art--a testament to Don's skill as a machinist.

During the lull in the current solar cycle, the 10 meter amateur radio band makes an excellent vehicle for local and regional contacts.  Please encourage your friends with technician class licenses to work some CW or SSB on this band.  Why not organize an informal, local net on 10 meters?  You can use Don's project to make something workable for your 10 meter work.

20 Meter Delta Loop Antenna. Post 1737.


. If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=Rq-9TAcCnxE

Here's an easy, inexpensive, and versatile antenna from Denis (VE3BF).  The classic delta loop antenna can be used for both home and field use.  The antenna exhibits modest gain and can be vertically polarized by feeding the antenna at the bottom.  To get multiband performance (20 meters through 10 meters), use 450 ohm ladder line, 300 ohm TV twin lead, or homemade 600 ohm twin lead in conjunction with a 4:1 balun and an antenna transmatch (i.e. "tuner").  I've built several variations of this design for 80-10 meter coverage.  Best of all, most of the materials can be found in  your "junk box" or at the nearest building supply or home improvement outlet. Have fun!

40 Meter Fishing Pole Antenna. Post 1736.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=PXg7ZOAkDyg

Operating your amateur radio equipment in field conditions can be a lot of fun if you have some compact, well designed equipment for your venture outdoors.  It goes without saying that a strong, easy to erect, and portable HF antenna will serve you well in Mother Nature's playground.

In this video, Denis (VE3BF) shows us how some wire, a simple 4:1 balun, and an inexpensive fishing rod can become the basis of a great outdoor antenna.  Denis uses a spirally-wound wire on a readily available Shakespeare telescoping 20 carbon fiber fishing pole from Amazon to form a simple, inexpensive portable antenna for 40 meters and other bands.  When you're done with operating, the fishing pole collapses into an easily carried package which can be stored with the antenna components in your vehicle for the next field or emergency situation. Also, this simple antenna can be used as an easily erected and take down antenna for deed-restricted properties.

Perfect HOA friendly antenna, discrete and stealthy Broadband Butterfly ...Post 1735.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=Y473hOmif-E

If you live in deed-restricted housing controlled by HOAs and CC&Rs, this antenna from Ron C may be of interest.  Ron calls this discrete and stealthy antenna the "Broadband Butterfly Terminated Dipole (BBTD). 

Ron takes you-step-by-step from design to finished product.  Although this project will take some time to build, the results will be worth it.  As long as neighbors can't see this antenna, you should be able to operate in peace  Also, you can try other in-house antennas, such as magnetic loops, small verticals, and half-wave dipoles spread over your ceilings.

160 Meter Inverted L Antenna. Post 1734.


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

Now that propagation is favoring the lower HF bands (160 meters through 40 meters), it may be a good idea making an antenna for these bands.  Because of the size of 160 meter antennas, you may have to make some uncomfortable comprises to use the "Top Band".  Inverted Vs and L antennas can offer you decent performance at a reasonable cost.

However, if you have a fairly large property with several tall trees,  you can follow Bob Holowenko's inverted L design and have a high performance antenna in a few hours.

Bob's antenna consists of 127 ft/38.71 m of wire with 6 X 127 ft/38.71 m radial wires.  Despite some limitations, Bob calls his homemade inverted L "one of the best performing antennas I've played."

Why not experiment with a variety of designs and configurations?  Antenna experimentation is one of the joys of Amateur/Ham Radio.  Considering the propagation issues of the day, Bob's design may just be the right 160 meter antenna for you.

HOA Stealth Backyard Vertical 10m-80m Antenna - MFJ-1979, RadioWavz P-80


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=4W5FFX3movg

Here's a nicely done multiband vertical antenna suitable for radio amateurs living in deed-restricted properties (HOAs/CC&Rs) or  lacking space to erect a full 1/2 wavelength horizontal dipole.  All you need is some creativity, a few spare parts, and a good radial system.

In this video, the antenna consists of a MFJ-1979 (1/4 wave 20-meter telescoping mast) a RadioWavz "Patriot 80: adjustable loading coil, a Hustler mast, and a MFJ-909 capacitive meter.  The key to making this homebrew vertical antenna is using a decent radial system and loss loss coaxial cable feed line.  An antenna transmatch (i.e. "tuner") could also be added to keep SWR losses low.  Such a system could also be employed for portable use during the ARRL Field Day, SOTA expeditions, or just casual operations in a public park.
