KH6JRM's Amateur Radio Blog

How the time flies when you're having fun. Not that
working in the radio station newsroom is all doom
and gloom, but now that my weekend shift is just
about over, I'm glad the cares of the world and our
financially-strapped state can be left behind until early
Monday morning when the news cycle begins anew.
I'm happy to squeeze in a few hours of amateur radio
operations--this provides a needed break from the
concerns of the "real" world.  The 40-meter loop
beneath my house is doing well for a "cloud warmer".
The noise level on this balanced lined antenna is very
low and it's a joy to listen to contacts without the usual
level of noise in my area.  Proximity to power lines surely
doesn't help, but the loop seems fairly insenstive to this
type of vertically polarized rfi.  The loop is great for my
local Hawaii state contacts.  The backyard vertical does
alright for DX, considering the dinky lot that encloses my
rental house. I'm not disappointed in the performance of
either antenna once I consider how inexpensive it was to
create either one.  Have a good weekend and try to remain
positive the doom sayers.  Allow at least one day to do some-
thing good for yourself, community, and loved ones.  Aloha
from Laupahoehoe. 73, KH6JRM (Russ).

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: 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: 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
