John,
I can't seem to locate my Xerox copy of the Krauss chapter on loops but will
keep looking The lobes shown in his figures were extensive (nice graphics,
too) but it may be that the examples I remember were for loops of many WLs
circumference.
I did manage to find a good article covering the radiation resistance for
loops of all dimensions. Turns out the radiation resistance is still very
small at 1/4WL. So does this say that most of your 53 ohms is ground loss
and/or tree loss? Lot of room in there for hours of exploration and possible
improvements!
