LA8OKA's Corned Fed Delta Loop



The Delta Loop antenna is one of the famous ”magical antennas”, but in reality, the Delta Loop antenna is not as magical as it’s reputation. Despite its reputation as a Multi band antenna, it is a single band antenna. It can be somewhat tricky to make a Delta Loop with a low SWR. But after a lot of experimentation I finally found a ratio between the lengths of the sides of the Delta Loop that give reasonably low SWR into a 50 Ω coaxial cable almost independent of the high above ground and other surroundings. This ratio also gives good results no matter orientation, but the antenna have most gain when Side A is vertical and Side B is horizontal.
