Build the best DX antenna-step by step guide

Image
  Here's another great DX antenna from Walt's (K4OGO) book "Salty Walt's Portable Antenna Sketchbook." In this video, Walt shows us how to build a vertical end fed half wave antenna for the 20 meter and 15 meter Amateur Radio bands. These moderate gain HF antennas are easy to build and simple to deploy.  Most of the materials for these antennas can be found at various online distributors.  You may already have some of the materials in your "junk box." These antennas are fund to build and can be enjoyed at both "field" sites and at your home station.

Posted by Mark Haverstock, K8MSH on June 3, 2026 at 1:15 pm Antennas may look simple—just a piece of metal in the air—but they are surprisingly sensitive to their surroundings. Nearby metal objects and trees can dramatically affect how an antenna performs, sometimes improving it, sometimes hurting it, and occasionally turning a perfectly good antenna into an expensive yard ornament. Radio waves don’t exist in isolation. Every antenna interacts with ...

Grounded Inverted L Antenna-Try This

Image
  If you live on a small urban lot, you know how difficult it is to use a decent antenna on the 160 meter and 80 meter amateur radio bands.  The size alone can make you abandon this fascinating slices of the HF spectrum. In this video, Peter Waters (G3OJV) shows us how a "reverse fed grounded L antenna" can get you on these bands.  Inverted L antennas can perform very well if you pay attention to how the antenna is fed and deployed.  A simple ground radial or counterpoise system and a 49:1 UnUn can help reduce the size of the antenna while boosting overall efficiency of this antenna.

Here are some comments from Peter (G3OJV): The Inverted L antenna has all kinds of possibilities. We recently covered the Reverse Fed Grounded L Antenna. Here we look at a simple method of ...
