Simple Ham Radio Antennas

How would you like to build a cheap, easily erected, and efficient antenna for your small yard?  I've pondered that idea over the past several days after a cold front and its associated high winds made a mess of my temporary, homebrew vertical next to my garage.  Since I had a few days off from my substitute teaching assignments, I decided to build another sky hook with materials I had in my "junk box."  I still had a good pvc mast, about 100 feet of number 14 housewire, and an extra 4:1 balun stashed in the corner near the washing machine.  Along with 50 feet of 450 ohm twin lead and about 20 feet of RG-6 coax, I was in business. The antenna would be an inverted "vee" inspired by a variety of articles in the ARRL Antenna Book, various amateur radio forums (e.ham, net), and a 1998 paper entitled "The $4 Special" by Joe Tyburczy, W1FGH.  The antenna won't rival a mono band beam on a 50-foot tower, but it will provide hours of good contacts at a sm...

While I was perusing the 03 January 2012 update to eham.net, I came across an interesting article by Bob Raynor, N4JTG, entitled "Where do we go from here?  Some thoughts on your first HF Antenna."  Bob does an excellent job of explaining the basics of antenna design that even techical neophytes such as I can understand.  Bob belongs to the school of "homebrew antenna design" with a goal of getting on the air with basic, cost saving, and easily built antennas.  I'm all for that, considering my reduced income as a new retiree. WHAT TYPES OF ANTENNAS ARE AVAILABLE AT A LOW PRICE/ Bob explores the design and building of several simple, yet effective antennas that are suitable for the space and financially challenged (that means me and thousands of other hams who are living in antenna restricted areas).  Included in his short article (with pictures) are the familiar center fed doublet fed with twin lead, the fan dipole, the basic dipole and inverted vee, and the...

Happy New Year's Greetings from Laupahoehoe along the beautiful Hamakua Coast.  This was the first day I could spend some extended time with my favorite pursuit--Amateur Radio.  There are no obligations until I return to the classroom on Thursday.  With that in mind, I checked out the "antenna farm" in the back yard and ran a few contacts in the Straight Key Night event hosted by the ARRL.  I found the 40-meter inverted vee did an excellent job on 40 and 15 meters.  It's good to see some propagation after several years of marginal conditions.  Before breaking for lunch today at around 2057 UTC, I decided to drop in on a "New Year's Net" hosted by Neal, AE1P up in New Hampshire.  His signals were excellent, running between 57 and 59.  It so happens I need New Hampshire for my QSL collection, so I just dropped my call into the roundtable, hoping a puny 5 watts could make the trip.  Wonder of wonders, he and a few others in the net were able t...

This has been a busy week at Laupahoehoe High and Elementary School.  Both my xyl and yours truly have been doing our thing as substitute teachers.  Today, we had a break before resuming our assignments on Friday and Monday.  Never a dull moment in the classroom. SUNDAY DRIVERS--HOPE FOR THOSE OF US CAUGHT IN THE CONTEST FRENZY During a few spare moments this morning, I found several interesting and entertaining articles in the December 2011 issue of "QST".  One that caught my eye was a short essay on page 63 by Rick Lindquist, WW3DE.  "Sunday Drivers--contesting in the slow lane can add a little spice to your life."  Being that I only dabble in a few contests and have a rather modest ham station, I found Rick's approach to the contest phenomenon both humorous and relatively stress-free.  Like Rick, I find the last day of a contest sometimes the best time to jump in and make a few contacts.  If you treat the contest weekend as mostly fun and d...

Happy Thanksgiving to all!  I'll return to my diet after I eat the traditional feast of turkey, sweet potatoes, cranberries, assorted vegetable, and some pumpkin dessert.  I walked an extra 2 miles today to compensate for my once a year indulgence.  I know, what I consume will take a marathon run to erase.  I'll try to limit my portions--at least that's the idea anyway. Among the articles I read over the past few days, were some of the comments from hams living in CC &  R and otherwise restrictive environments.  E-ham.net's antenna forum contains several interesting articles that may prove useful to those of us challenged by our lack of real estate.  One operator whose call escapes me at the moment mentioned his successful use of the MFJ-1622 Apartment Antenna that allows coverage from 40 through 2 meters.  The antenna is described on page 69 of MFJ's 2012 Ham Catalog.  The antenna consists of a sturdy clamp for attachment, a "bug ...

A loop approach to restrictive antenna conditions. As I was reading the November 2011 "QST" today, I ran across an interesting antenna idea from Cristian Paun, WV6N.  His article entitled "An Antenna Idea for Antenna Restricted Communities" on page 35 really hit home.  My space restrictions are severe and the antennas I use certainly work (inverted "vees", vertical monopoles, and loops), but they could be better and perhaps even smaller.  Cristian describes a small loop he built and placed in his garden.  Previously, he had been using various mobile antennas between 3.5 and 30 MHz with some degree of success.  He wondered if he could use less space and yet produce results surpasing his best efforts.  Apparently, the small magnetic loop he designed and used proved most useful, with some improvement over the mobile antennas he once used.  Cristian's instructions are fairly simple and the final product is attractive, discrete, and almost sculture-like....

Hawaii QRP Club meets After the passage of a few months, the Hawaii QRP club held a meeting with the Hawaii Council of Radio Clubs at the "Back to the 50s Fountain" in Laupahoehoe--my qth.  Since the meeting was only .7 of a mile from the qth, I decided to drop in and talk with the Hawaii Island hams I hadn't been able to see in person because of my former job.  As a newsman, I usually worked seven days a week in Hilo, making direct contact with local amatuers very difficult.  So, once I retired, I vowed to keep a more active schedule with my fellow hams.  The Hawaii QRP Club meets daily at the Hilo Jack In the Box, just outside of Hilo, from 0600-0800 local time.  I won't be able to make most of those meetings, because I'm on standby as a substitute teacher for Laupahoehoe High and Elementary School.  So, it was a great experience to trade tall stories with those I've only contacted on the air.  Since I retired on 30 September, life has become more ...

Antennas--a cautionary tale While reviewing the latest edition of eham.net, I ran across an interesting antenna "classic" by Don, W8AD.  "HF Antenna installation hints", originally published on 12 November 2006, offers many useful installation tips for those of us facing space retrictions, HOA and CC & R problems, and nosey neighbors.  Don provides a review of slopers, dipoles, antic antennas, and site locations for the intrepid radio amateur.  The follow up comments are also worth a read.  Don has written a good, basic primer for those of us a little rusty on the design and limitations of our "antenna farms." Halloween is past and all of winter lies before us This Halloween at the qth was wet, windy, and dangerous for those brave enough to do the "trick or treat" routine.  A cold front passed Hawaii Island Monday afternoon bringing several inches of rain, wind gusts of up to 40 knots, and generally dangerous driving conditions.  Many f...

CQ WW DX SSB contest I've never been much of a contester.  Before I retired, there just wasn't enough time to fully engage in one of the exciting phases of amateur radio.  There was always something that restricted my time at the old Swan 100-MX.  Now that I've removed myself from the daily routine of getting up at 0230 hrs local time for my news shift at Pacific Radio Group, time has been more generous.  With the CQ WW SSB contest in full swing, I tried my hand at a few pile ups...not too successful, but I did manage a few contacts with my modest station.  Running around 10 watts SSB into an inverted "v" and a homebrew 20-meter vertical dipole surely made for some frustrating moments, but I enjoyed every minute of my limited exposure to the contest.  The October 2011 edition of "CQ" had a nice article on contesting by Geroge Tranos (N2GA), who showed how emergency responders and contesters share many of the same attributes.  This is an article worth...

Final step completed--new career awaits After 3 weeks of intensive study and three exams, I finally finished my substitute teacher course and submitted all of the necessary paperwork.  In a short time I should be getting my certificate and the opportunity to end this lifetime as a teacher.  It's sort of ironic.  Before I became an amateur radio operator back in 1977, I started out as a teacher.  Life took its inevitable twists and turns, with work ranging from an air force officer to a radio newsman and broadcast engineer.  And now, I've come full circle.  I'll end my days as a teacher.  The circle is closed. More time for Amateur Radio Between teaching assignments, I can devote more time to my main diversion all these years--Amateur Radio.  I hope to get on the air more often and build more antennas.  Speaking of which, I was reading a 1978 edition of "The ARRL Antenna Anthology" and came upon a simple ground plane antenna that sh...

Exchanging the old life for a new one Eversince I retired from Pacific Radio Group on 30 September 2011, I've been attending classes to get a substitute teaching certificate from the state of Hawaii Department of Education.  I should complete the academic work and the required exam by 21 October 2011.  Once I get interviewed by my wife's school (she is a substitute teacher at Laupahoehoe High School and once served as its school librarian), I should find some temporary work until I get my life fully in order.  After 40 years of broadcasting (both in the military and in civilian life), I welcome the chance to try something new.  I suspect I will enjoy teaching, so this retreaded announcer could find himself before the toughest audience of all--students. Amateur radio will occupy more of my spare time I have a list of antenna projects to complete, numerous household chores that are due, and some slack time to enjoy the remaining years of my life.  No regrets...

New Beginings On 30 September 2011, I left my post as News Director of Pacific Radio Group (Hawaii Island) to enter a new phase of my life--that of retired  senior citizen.  After almost 40 years of delivering the news, questioning politicians, and answering thousands of phone calls from the thoroughly sane to those bordering on the truly outrageous, I've turned off the Shure S-7 broadcast micorphone and opted for a more quiet life along the Hamakua Coast of Hawaii Island.  Presently, I attending recertification classes to qualify for a substitute teachers certificate  so I can teach at the same school my xyl does.  So much for idle time. The Old Antenna Farm gets a face lift. With retirement and some teaching time, I'll be able to devote more attention to squeezing every last watt out of my modest range of antennas--the inverted 40-meter "vee", the 40-meter vertical, and the 40-meter loop under the house.  In the past, my amateur radio time has ...

WELCOME TO THE NEW AGE OF INSTABILITY The weekly news cycle is coming to an end.  After a week of generally disturbing economic, political, and international news,  I'll be glad to flee the radio station news room for some peaceful hours at the amateur radio station nestled in the back bedroom of my home.  One thing is for sure in the news business--it is never dull, no matter what you hear and read.  There is always something building that will break out in a banner headline in the days to come.  Keeping up with all of the twists and turns of the current day surely makes for a busy day.  After doing 30 or so newscasts on our four program streams, I am ready to vacate the media circus for the relative calm of my modest neighborhood along the Hamakua Coast.  Sometimes I wonder how things got so out of hand in my country.  Even after 33 years in the news gathering business, I am still amazed how normally decent, intelligent people can be so taken ...

NEW ANTENNA FINALLY UP Over the course of the past few days, I finally added another skyhook to my modest antenna farm.  It took a few days to secure a few sections of 2" pvc pipe and to  assemble the wire, coax, and twin lead for the project.  The antenna consists of 32' of pvc pipe, 32' of 14-gauge housewire, 32' of 14-gauge wire serving as an elevated counterpoise, and 40' of 450-ohm twin lead attached to a 4:1 balun.  Approximately 15' of RG-6 coax runs from the balun to the Drake MN-4 ATU.  IS THIS BASIC ANTENNA A DX BUSTER? No.  But it does work and can be used from 40-meters to 10-meters.  The design goes back to the 1920's and has been refined over the past years by many noted amateurs.  Other than buying a few pieces of pvc pipe, my expenses were zero.  Fortunately, I have a well-stocked "junque" box and was able to find nearly everything I needed on site.  I'm enjoying this simple antenna, given the space restriction...

9/11 REMEMBERED Hawaii amateur operators joined the rest of the nation in commemorating the tragic events of 11 September 2001--an event that changed this country and affected the lives of thousands around the world.  On Hawaii Island, residents observed a moment of silence at 7 a.m. Sunday to observe the event. I remember that day very well.  I arrived shortly at the radio station shortly after 3 a.m. and joined my then morning man, D.C. Carlson, in an all-day, total news broadcast.  Our usual Adult Contemporty format was shelved until 3 p.m. as we aired coverage from the Associated Press, ABC, and CBS.  Chris Leonard, the manager of our cross-town rival KWXX-FM, lost two close friends and a cousin in the tragedy.  Many Hawaii  Island residents knew friends and family who perished on that terrible day.  On that day, at least, all of us were one in mourning that dreadful day.  If my memory serves me, I lost my voice shortly after 3 p.m., ...

HOLIDAY IS OVER...IT'S BACK TO AMATEUR RADIO Now that the Labor Day weekend is over, the news room can return to the normal mix of devious politicians, economic confusion, and the usual helping of local crime, prep football, and the ongoing financial crisis in Hawaii County.  Sound familiar?  It seems as if every community in the nation is facing pretty much of the same thing.  Add a few natural disasters such as raging fires in Texas, drenching rains along the Gulf Coast, hurricanes in the Atlantic, and typhoons in East Asia and you have the ingredients for keeping news people employed.  Welcome to the new definition of normal--whatever that is.  With a return to the normal work schedule, I can allocate some more time to Amateur Radio and the reheating of the ionosphere. ANTENNA IDEAS REVISITED During my lunch break, I paid a visit to eham.net and its always fascinating forums.  An antenna article by Craig LaBarge (WB3GCK) caught my eye.  In the...

MOTHER NATURE KEEPS US BUSY This week has been filed with enough stories to keep any news person busy.  For those of us on Hawaii Island, what was left of Tropical Storm "Fernanda" didn't create any disturbance other than a few windward showers and some higher than normal surf along the southeast shore.  My heart goes out to those facing the trial of Hurricane "Irene"--this looks like a very nasty storm.  It's good to see many people are preparing ahead of time for the storm's arrival or leaving the danger area before high winds begin.  I expect amateur radio operators are gearing up for  whatever Nature throws at them.  Having experienced several hurricanes and tsnuamis in Hawaii, I know these developments should not be ignored.  It always amazes me that there are those who choose to ride out the storm rather than "get out of dodge".  I suppose it's a personal decision, but why tempt fate?   For us in Hawaii County, the passing of "...

Hawaii Island amateur radio operators are breathing more easily now that the Central Pacific Hurricane Center has downgraded Tropical Storm "Fernanda" to a tropical depression with maximum sustained winds of 35 mph.  Remnants of this once potent storm should pass south of Hawaii Island Sunday or Monday, bringing a few showers and higher than normal surf.  It appears those of us on Hawaii Island have dodged the proverbial "bullet".  Local civil defense officials are keeping an eye on "Fernanda" just in case it pulls a switcher-roo like Hurricane "Iniki" did twenty years ago.  "Iniki" passed south of Hawaii Island as a weak tropical storm and then found warm water, regained category 4 strength, and flattened most tall objects on the Island of Kauai.  The "Garden Island" lost nearly all of its communications infrastructure, many homes, and several businesses.  It took months to rebuild the place, thanks to National Guard personne...

Homebrew antennas are an endless source of experiment, creativity, and occasional frustration.  Armed with a few good antenna books from the ARRL,CQ Publications, and the RSGB, I've built a variety of  verticals, dipoles, and loops which work most of the time.  Since I'm not an electronics wizard, there have been a few ideas that just didn't pan out, including a homebrew 1/2 end-fed hertz that developed a bad case of corona discharge at the end of the antenna.  That 40-meter project was a disaster, but it taught a few valuable lessons about matching devices, baluns, and swr.  I think the next time I want to use an end-fed hertz, I'll violate my long-standing rule of "rolling my own" in favor of a commercial product by Par Electronics, Radiowavz, or Comet.  I'm alright when it comes to simple verticals, dipoles, and loops.  Anything beyond that calls for more study and careful attention to detail.  I'm still in the learning process--something that ...

This week has proven busy for those who call a broadcast news studio "their home away from home."  With all of the debt-ceiling talk and arguments on just how insolvent we are, there is sufficient news to keep this announcer occupied.  There hasn't been much time to relax before the ole Swan 100-MX and enjoy a casual qso.  This weekend will be fully engaged as well with a full schedule of drag races at the Hilo Drag Strip.  I work as the tower announcer, a role that keeps me out of trouble for the entire weekend.  Despite a jammed week, I've managed to pursue a number of antenna articles and related projects.  The August issue of "QST" contains an interesting description of an elevated 40-meter monopole with two-tuned counterpoise wires.  The skyhook seems to work alright, so, if you have a convenient tree or pole in the backyard, you may want to experiment with this antenna.  Of course, those of us without such supports will have to be more creat...
