The R9 MM now comes with a T Dipole Antenna.

The newly released R9MM receiver is pretty darn small and retains the majority of the features of the R9 Mini. It still has super low latency, high precision and a very low mass. The most important new feature is that the S-Bus port has been inverted to make the R9MM compatible with a wider range of external devices.
