Half Square Antenna Tips and Tricks.

Image
A properly designed and built Half-Square HF Antenna is compact and capable of delivering a bidirectional gain of approximately 3dB. In this well-paced video, Peter Waters (G3OJV) shares some fascinating suggestions on how to maximize the performance of this simple HF antenna. The "classic" Half-Square antenna is perfect for the ARRL Field Day, portable operations, or even for home station use.

Here are some comments from Peter (G3OJV): The Half Square antenna is capable of fitting into a small space, and this 20m version offers 3dB gain in two directions. It requires only 10m garden length and can be configured to also operate on 40m, 15m and 10m as well as 20m. Even 80m operation is possible with a simple home made add-on.

The photos in this article show an antenna I made for field day and erected as a NVIS inverted V. It was used on 5 hf bands with a tuner. The apex was at 20 feet and the ends were 10 to 15 feet above ground. We worked 15m, 17m, 20m, 40m, and ...

Building a vertical dipole antenna for 6 meters.

Image
Propagation on "The Magic Band" or 6 meters has improved considerably over the past few months, thanks, in part, to Solar Cycle 25. Now's the time to experiment with simple, easily-made antennas for 6 meters.  In this video from Walt (K4OGO), we learn how to design, build, and test a basic vertical dipole for "The Magic Band.'

Build it: Black Widow Antenna-A 15 meter Moxon Antenna.

Image
If you're looking for a simple ARRL Field Day Antenna that exhibits a low takeoff angle and shows an improved signal to noise ratio, then this 15 meter Moxon Antenna built by Michael Martens (KB9VBR) is the answer. Michael takes us from start to finish in this well-made, easy-to-understand tutorial. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=4ddtVW8HweM Here are some comments from Michael (KB9VBR): The Moxon is an 2 element Yagi style antenna that boasts of a low takeoff angle and high front/back signal to noise ratio. The 15 meter Black Widow Moxon is an excellent antenna for Field Day or other events were a lightweight, portable antenna is ideal. Follow along as I build a Moxon antenna out of fishing poles and other common parts. -- References -- KG4JJH Black Widow 15 Meter Moxon Antenna: http://www.kg4jjh.com/blackwidow.html AC6LA Moxgen Calculator: https://ac6la.com/moxgen1.html Building the ...

Why do some verticals have radials and some don't.

Image
An in-depth discussion of ground radial and counterpoise systems from David Casler (KE0OG). Dave does an excellent job of explaining the theory behind ground radial systems for vertical antennas.  Not all vertical antennas require a counterpoise or an extensive radial system to function efficiently. Dave examines several types of HF vertical antennas and describes the ground radial or counterpoise system best suited for those antennas.
