Delving Into the Delta Loop!

Delta loop antenna is simple to make if you have two high supports or two low supports and one high support. It has directivity along the broad side and a low noise level. 4:1 balun needed at feedpoint could be replaced by a quarter wave 75 Ohms matching section. Multi-band operation is feasible, with and without tuner. Multi-element directional delta loop antennas have been made for higher bands with wider beam width for a given gain than Yagi-Uda antennas.
