KH6JRM's Amateur Radio Blog

The news cycle is winding down at KKBG-FM/
KHLO-AM for the workweek.  Only half-days
on Saturday and Sunday remain on the horizon.
The break will give me plenty of time to work on
my spartan "antenna farm" at the Laupahoehoe
qth.  With my tropical climate and salt air, there
is always something to do for the skyhooks.  Be-
sides, the work gives me a break from the rather
dismal series of events that is making everyday
life more difficult than it should be.  I just finished
an excellent article on the eham.net website by
Phil Chambley, K4DPK, entitled "Your First
Dipole."  Phil's article is a basic tutorial on an
antenna that has served me well in the past.
You can expand his idea into a "fan" dipole and
get some added coverage for very little money.
I may even string up one of his simple dipoles as
an inverted vee and see what I can do.  My yard
won't permit a fully extended dipole, hence my pref-
erence for verticals and low slung loops.  The out-
lay of cash and time will be minimal, since I have
most of the materials in my junk box.  This little
project should be fun.  Nothing like a litte therapy
to clear the mind.  Have a good weekend and en-
joy the ESPN news to the right and the Yahoo
news at the bottom of the page.  73 de Hawaii
Island.  KH6JRM.

G5RV Multi Band HF Dipole Antenna. Post #1555.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=aeNHIQ_j4Dk This well-produced and richly illustrated tutorial on the classic G5RV HF Dipole Antenna was presented to the Brandon Amateur Radio Society in Brandon, Florida in 2017 by Bernie Huth (W4BGH).  Bernie does an excellent job of  explaining the pros and cons of this popular HF antenna from the late Louis Varney (G5RV).  Although Varney envisioned his design primarily as a 3/2 wavelength antenna for the 20 meter Amateur Radio band, radio amateurs have used the antenna for multiband use.  The G5RV is an excellent choice for the 20 meter band.  Performance on other HF Amateur Radio bands is good enough to qualify as stand alone HF antenna if you can only erect one HF antenna.

Amateur Radio Bicycle Mobile Setup. Post #1554.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=2zWb-KnkGdY. Here's a way to use Amatuer/Ham Radio while you work on shedding a few pounds in useful exercise.  Why not equip your bicycle for 2 meter/70 cm mobile operation? In this short, well-made video, "taverned" shows us how he used a mag mount antenna, a simple C clamp, and a basic ground system to convert his mountain bike into a mobile station.  The project is straight forward, simple, and gives you emergency communications while you peddle down the road.

An 80-Meter Vertical Helix

Like many amateur radio operators, I live on a small lot surrounded by neighbors, utility lines, and civic-minded citizens concerned about the "attractiveness" of my community.  Whether by design or outright fear, I've adopted the "stealth" approach to ham radio antennas.  It's the old "out of sight, out of mind" idea applied to amateur radio antennas. The amateur radio press is full of articles describing the struggle of amateur radio operators to pursue their hobby under the burdensome regulations of CC & Rs, HOAs, and other civic minded citizens who object to antenna farms.  So far, my modest verticals, loops, and inverted vees have blended well with the vegetation and trees bordering my small backyard.  Vertical antennas have always been a problem because of the limited space for a radial system.  There are times, however, where a shortened vertical for the lower HF bands (such as 80/75 meters) is necessary where horizontal space is lack
