Delta Loop UN7CI for 7, 10, 14 and 21- MHz
The antenna has SWR less the 2.0:1.0 at height of the lower side 1.2 meters above the ground

Costruiamo una delta-loop
La delta loop e' un'antenna semplicissima e molto economica, costituita da un triangolo di filo chiuso lungo un'onda intera moltiplicato per il coefficiente di velocita' della RF nel filo di rame
