All good points. you could add that the antenna would better represent free space..... I wonder what the effect of Cal factors would be?
Less issues matching a complex source impedance like and antenna to the non-perfect impedance of a cable. Elimination of temperature effects of the cable dielectric. I'm sure there are more.
