This SMA 45 Degree Connector is useful for pointing antennas on both your quad and goggles upwards.
Omnidirectional antennas actually have a dead zone in the vertical axis, so it is best to keep them vertically oriented during flight and on your goggles. Using a 45 degree connector is perfect, since most quads fly forwards at an angle of 30-45 degrees.
Directional antennas on goggles work best when they are pointed straight forwards and by using a 45 degree connector, you can adjust the upwards angle of your directional antenna by rotating the connector. This way, you can add between 0 and 45 degrees of up tilt on your goggle antenna.
Increase the Lifespan of your Goggles and Vtx Connector
SMA and RPSMA connectors have a limited lifespan and using an additional connector between your antenna and goggles or Vtx increase their lifespan.
RP-SMA (Male) to SMA (Female)
Use this connector to adapt your male (non-DJI) antennas to your DJI Goggles
RP-SMA to RP-SMA
Use this connector to extend the life of your DJI Goggles.
These goggles are great, mainly due to the Steadyview VRX. Screen is bright and clearer than my EV800D, and looks better even though slightly smaller. These are much lighter weight and more comfortable.
Using in my goggles and in TX. In TX they work great as it uses a pair of them. Kind of short battery life on my goggles that only use one, but I charge both and just swap them out which works fine.
Compared to Matek M10Q-5883 on the same 7" quad and same location the Holybro M9N outperforms others in speed locking satellites, achieving DGPS. Also, due to the internal battery it retains previous GNSS location, satellites etc. for fast reboot in the same location.
