My first reaction is that 27 ohms in a real life situation with nearby
trees and buildings is pretty close to a theoretical 36 ohms for a
monopole in the clear over a perfect ground, and possibly within typical
measurement accuracy limits anyway, but if you read the link below
you'll see that feedpoint impedance is not an absolute indicator of
performance anyway.
