FatShark Dominator V2/V3 5.8ghz Diversity Receiver 32Ch Goggle Module V2 FSV2445
The Fat Shark Antenna switching diversity module combines the coverage of directional and omni antennae into a single receiver. Installs directly into modular equipped Fat Shark headsets. Receives common bands (Fat Shark, band A, E and the popular Race Band).
Comes with 2p SMA adapter. 45 for direction and 90 for omni, white module bay door. (black not available for Atti V3 yet - tba)
Note: That this is not a true diversity solution, it is an antenna diversity that combines the range benefits of an omni and directional antenna. It does not reduce video breakup (other than the benefit of better signal strength of directional antenna) nor is the receiver suitable for flying at limits as in snow conditions it will switch between antenna looking for best signal.
