How to build a delta loop antenna

Image
If you want a low noise, moderate gain, and efficient HF antenna, please try this delta loop design from Hiram Vazquez. Hiram takes us step by step through the design, construction, and testing phases of this popular HF antenna. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=QJl3S9x6K_I Here are some comments from Hiram: This video explains how to build a Delta Loop antenna and a Q-Match for it. The Q-Match will make the antenna resonant at 50 ohms at the feedpoint. This eliminates having to buy an expensive balun. The Delta Loop is bi-directional and has some gain. It is compact, easy to construct and inexpensive. You may already have all the components lying around. Good luck. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).

The ZS6BKW multiband HF Antenna is an excellent alternativer to the popular G5RV antenna. In this video, Steve (AD4XT) offers a comprehensive guide to the theory, construction, testing, and use of this simple, effective HF Antenna.

This antenna design has been out for quite a while. No tuner needed on most of the HF bands. A good alternative to the G5RV. This is an easy antenna build. You will need some 450 ohm window line and some wire. I found a cheap center T insulator on Ebay that really made this build go smooth.

Chuck takes us step by step throught he design, building, testing, and use of this versatile HF antenna.

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 short 40m antenna with coil and AT-271 whip

Image
If you have access to a TRC-372 manpack radio and its antenna accessories, you'll have a nearly perfect portable HF system. In this video from Gil ("Radio Prepper" video channel), we see how a coil and an AT-271 whip can make an excellent choice for field or emergency operations. As Gil relates, this experiment had some issues, especially with the construction of the coil. If you can't see the video, please insert this title URL into your browser searchbox:  https://www.youtube.com/watch?v=d8TO2O2KOn4 Here are some comments from Gil: Things did not work as expected with this great design by VA3TNE on Thingiverse. The coil is used with an AT-271 military antenna whip, 3D printed and tested here with my TRC-372 manpack radio at the Col de Vence North of Nice. Maybe someone more experienced with coils could shed some light on the issue... STL 3D files: https://www.thingiverse.com/thing:235...
