Simple Ham Radio Antennas--How to build a Delta Loop Antenna. Post #415,

A clean, simple tutorial by Hiram Varquez on how to build a delta loop antenna and a Q-Match for it. According to Varquez, "The Q-Match will make the antenna resonant at 50 ohms at the feedpoint. This eliminates the need for an expensive balun." The delta loop antenna is bidirectional and exhibits some gain over a dipole. The loop is compact, easy to build, and inexpensive. Although Hiram's delta loop is designed for 20 meters, you can scale the loop for any amateur band between 160 and 10 meters, depending on the space available. If you want to use the delta loop for HF bands above 20 meters (12, 15, 17, and 10 meters), replace the coaxial cable and Q-Matching Section with 450 ohm ladder line and a balanced tuner. Delta Loops are excellent antennas for home or portable use. For the latest Amateur Radio news and events, please check out the blog sidebars. These news feeds are updated daily.
