Locating Transponder Antenna on top of the fuselage instead ofunder it.

I am thinking of the theoretical advantage in drag coefficient of a blade vs rod antenna which holds for any speed.
Assuming, as previously stated, that the blade antenna is aligned with the airflow around the fuselage at that point.
I would think that the drag of a misaligned blade antenna could be significantly higher than the perfect alignment drag.
For that reason, I'm personally going with a rod and ball antenna. The manufacturer's recommendation for mounting a transponder antenna is in an area where I have no idea how the air really flows.
Does anyone know if the difference between a perfectly aligned blade antenna and a rod and ball antenna is at all significant at, say, 100 kts airspeed?
