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).
