I had a full size delta loop for 80 which worked well on 80 DX. I changed
the feed point from the bottom corner to 1/4w down from the apex and
it worked extremely well for 80 dx, very noticeable improvement with the new
optimum feed point. I fed with balanced ladder line and also used it on 40
meters.
It would not out perform a full size 40 vertical dipole I had strung up however
for DX. I suspect as a 2 wavelength loop on 40 the radiation angle was changed
(for the worse)
My two cents.
