Invisible 5-Band Antenna

Image
Here's another clever "stealth" antenna idea for radio amateurs living in deed-restricted housing. Peter Waters (G3OJV) shows us how to make and use a 5-band "invisible" antenna for crowded urban conditions. Despite the drawbacks of such an antenna, it will get you on the air without disturbing your neighbors.

The Ultimate Antenna Guide

Image
Thanks to Callum (M0MCX) for this inspirational and practical road map to what he calls the "Ultimate Antenna Guide." This video was created following a presentation to the RSGB Convention of 09 October 2021. This "guide" contains a variety of practical, inexpensive suggestions for improving the performance of your home station or portable antenna system.

Ham Radio is a Science Based life-long-learning activity. This is an ideal presentation for a Club meeting on a cold winter's night! Enjoy it. I had fun making it. Callum. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).  

Extended Double Zepp Antenna

Image
Stan Gibilisco (W1GV) provides a good theoretical explanation of the "classic" extended double zepp antenna, a design consisting of "two 5/8 waves in phase." The antenna can give you around 3 dB of gain over the standard dipole antenna.

How to make a 20 meter Moxon antenna for home or portable use.

Image
Excellent tutorial from Chuck (KK6USY) of the KK6USY Ham Radio Adventures video channel.  If you want a simple, effective antenna for the Amateur Radio 20 meter band, please consider the popular "Moxon Antenna." Chuck takes you the basic knowledge and construction techniques needed to make this lightweight, portable antenna. If you can't see the video, please insert this title URL into your browser searh box: https://www.youtube.com/watch?v=8gHY1b4pauk Here are some comments from Chuck (KK6USY): he Moxon is one of the Best portable Gain antennas and easy to make! In this video I show how I made a 20 meter Moxon Antenna for portable operation like POTA or SOTA. Yea I know SOTA might be a stretch for most of us! If you make this antenna for home use, I would beef up the base plate and use a heavier gauge wire 18 -12awg. Also look into some heavier duty fiberglass supports for the spreaders.

Building a Hen-Tenna for 2 meters

Image
Thanks to Paul (VK3HN) for this curious, innovative 2 meter mantenna known as the "Hen-Tenna." The antenna, first designed and used in Japan, has attracted the attention of antenna experimenters over the past few years. According to Paul (VK3HN), the antenna is easily-built and provides a modest amount of gain on the 2 meter band (around 3dB). If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=u-35o0x6vgQ Here are some comments from Paul (VK3HN): Hen-tenna is a rectangular loop antenna (of Japanese origin) that hangs vertically but, surprisingly, is horizontally polarised. It is simple, compact and offers over 3dBd gain broadside. It is quite broad in its resonance, mine was under 1.3:1 from 144 to 146MHz. This video shows a version being made for 2m SSB, and a field test. Hentenna calculator: https://www.la2pj.net/software/henten... My blog: https://vk3hn.wordpress.com/ VK3HN's homebrew 2m SS...

The best portable antenna you've probably never heard of

Image
Thanks to Australian radio amateur Peter Parker (VK3YE) for this excellent tutorial on the pros and cons of the "Bobtail Curtain" antenna--a wonderful choice for low-angle DX contacts. Although some construction expertise is needed for this antenna, the results far outweigh the time and effort used to design, make, and use this innovative antenna design. I've been impressed with "Bobtails" and "Half-Squares" since my earliest radio experiences during ARRL Field Day events.  You'll be surprised how the higher HF bands (15-10 meters) come alive with these innovative antennas.

Consider it if you want a low radiation angle for DX, don't have very tall masts and wish to operate on or near a conductive surface. A good write-up on the ...
