If you use a patch antenna on your goggles you already know it stick out at an annoying angle and as they are directional you need to face your quad just turning your head towards the sound doesn't work.
With a 45 degree SMA adapter you can mount your antenna to your goggles and it will face forward. You can also angle the patch slightly upwards so you don't waste some of your cone of coverage by having it look at the floor.
The SMA Female end connects to the device and the male end to your SMA antenna (See the attached images).
Compatible with the ImmersionRC/FatShark standard.
Flying weight: 2g
Goggles and patch antenna not included (Duh!)
