I am modeling a 20M 2-element delta loop array with the apex up, 12-foot
spacing and the bottom about 35 feet above ground, fed at a lower corner,
using Multi-NEC and NEC2. In driven/reflector configuration, it looks
about like what I'd expect - 6 dBi gain and 14-18 dB F/B. But in the
driven/director configuration, there isn't much directivity at all,
regardless of frequency.
Does this square with others' experience, or am I messing something up in
the model?
