Antenna Topics

A SLIGHTLY NEW BEGINNING:

Welcome back to my original Amateur Radio Blog, which has been retitled:  KH6JRM's Amateur Radio Antenna Topics.

This blog has been idle since late 2012 because of my changing job situation and the expansion of my original blog topic to include the latest Amateur Radio News.

The news blog began early this year using my original title: KH6JRM's Amateur Radio Blog (http://kh6jrm.com).

When I started reporting Amateur Radio News, I found the task complicated by an oversupply of information and a lack of time to follow my experimental antenna ideas.  The reaction to my news blog has been gratifying and I refer those interested in the latest Amateur Radio developments to access that site.

I've also received some notes about my neglect of simple antenna ideas--a subject that was the original focus of this antenna blog.  So, I've split my interests into two blogs that will hopefully answer both inquiries.  My revised antenna blog will be found here--http://kh6jrm.blogspot.com.

I plan to make several posts a week, teaching schedule permitting, of course.  All of my original antenna posts are at this site, as well as on the news blog.  I will keep this site very informal.  Most of my comments will be drawn from my antenna notebook, which records both my successes and failures in making homebrew antennas.

From time to time, I will also review equipment that I've found helpful in pursuing my Amateur Radio interests.

In summary, I now have two Amateur Radio blogs--one concentrating on Amateur Radio news and trends (http://kh6jrm.com) and the other focusing on homemade antennas (http://kh6jrm.blogspot.com).

As always, your comments are welcome.  Where possible, I will cite references and guidance received from my research, so you can build and improve what I've done.

My comments aren't those of a professional antenna designer or electrical engineer.  They are the result of my efforts to understand what works and why.  Although I've had almost 40 years of commercial broadcast experience, I still consider myself an "amateur" and a searcher for practical knowledge that works.

So, please join me at either site.  I'll keep you up to date on the latest Amateur Radio happenings, as well as my attempts at making the "ideal" antenna.

I'm looking forward to hearing from you.

Aloha from Hawaii Island,

Building a ZS6BKW antenna from scratch. Post #1559.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=BfUbL_4VCww. The G5RV and its popular variant, the ZS6BKW, are popular multiband HF antennas for radio amateurs. In this video, members of the Stamford Amateur Radio Association W1EE,  show us how to build a ZS6BKW antenna capable of covering the 80 to 6 meter amateur radio bands.  Here are the guidelines offered by this construction team: "The ZS6BKW is the successor to the G5RV. It's a multi-band 80-6 meter wire dipole. ZS6BKW started with the G5RV and then conducted extensive computer modeling to increase the gain, flatten the SWR a bit, and smooth out the lobes. It's also about 10 feet shorter than an equivalent G5RV. The antenna must be fed with 39 feet of 450 ohm ladder line and also must have at least 70 feet of coax feeding the ladder line. The coax and ladder line together form a matching network that brings the SWR below 2:1 (

Antenna for Condo Backyard-Stealth. Post #1542.

Don't let deed-restricted properties (HOA/CC&R) stop you from enjoying Amateur Radio.  In this video from AC2RJ, we see how some well-placed trees, a camera tripod, a telescoping fiberglass mast, and a "V" antenna can get you on the air without a lot of effort.  Add an antenna "tuner", a sturdy rig, such as the Yaesu FT-817, a microphone/cw key, and a simple grounding system, and you have a fully functional, nearly invisible ham station in your backyard.

G5RV Multi Band HF Dipole Antenna. Post #1555.

Image
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.
