When I say radiation resistance I include the small copper resistance also,
which is negligible on this heavy copper wire delta loop.
An important part of my post was about using the right words to describe
physical reality. Radiation resistance is a characteristic of an
antenna, and can be used to compute antenna efficiency. That's NOT what
you're measuring. You are measuring feedpoint impedance (assuming you
can connect at the feedpoint AND that your measurement setup doesn't
change the impedance).
So please call it what it is -- the feedpoint impedance, which your
analzyer probably reports as Rs + j Xs). :)
