I put up what I call a squashed delta loop in Colorado in 1994 and it
worked just fantastic. I put the base of the antenna 10 feet above ground,
and the apex at 100 feet above ground. Using the formula 1005 divided by
frequency the wire length used was 539.4 feet, 199.4 feet for the bottom,
170 feet on each angled side. I fed the antenna 35.1 feet (0.08 wavelength)
up from a bottom corner for vertical polarization, with an EZENEC 3.0
calculated takeoff angle of 23 degrees.
The delta loop will outperform a 160 meter dipole at 250 feet and most 1/4
wave verticals.
