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.
