The antenna at Hilton Head, Island, SC is a full wavelength 40 meter Delta Loop constructed of ~144 feet of #14 insulated wire configured as a equilateral triangle. The apex of the Delta Loop is suspended from a insulator hanging from a limb at ~58 feet on a "pine tree tower" behind the house. The feed point is at a lower corner of the loop via a 4:1 Balun from DX Engineering. The SWR varies from 1.0 to 1.5 over the 10m, 15m, 20m and 40m bands.
