Just anecdotal evidence here, but my Stemme came with a rod and ball
transponder antenna under the nose bowl.Â* I mounted a blade type antenna about 6 inches aft of that for the Flarm B.Â* I haven't noticed any difference in flying qualities, drag, etc.Â* Maybe it's measurable but who cares?Â* I'm not in contention for a world record or title.

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? Lou -- Dan, 5J |
