Have you considered flush antennas, like slots?


Slot antennas have the maximum lobe perpendicular to the rocket axis.
There's very little signal below the rocket. This is why tracking
stations are far away from the launch site. If the rocket were
overhead, and going straight up, there's no signal.


That was my first thought on side mounted antennas.

The best solution would be something on the fins if that were
possible with the airframe design.
