    $\begingroup$ I'd guess those are localizer antenna with an aerodynamic dielectric fairing. Many aircraft are fitted with similar designs $\endgroup$ – Carlo Felicione May 20 '17 at 17:21

What you observe here are VHF nav antennas for a VOR receiver. This antenna design is lower drag than wire whip antennas.

The antenna serves no aerodynamic purpose except to minimize its own drag profile.
