Angled SMA or RP-SMA bracket for mounting the Vtx antenna out the back of the quad.
For use with a pigtail (also called antenna extension cable).
The adapter slides over the spacers, and can optionally be fixed in place with a bit of hot glue.
I made this by modifying a similar adapter for the Hive210, making it wider to support the 3cm width between the spacers on the QAV210 frame, and made the opening where the SMA connector is mounted a bit wider, making it easier to install the connector (in the original part it was a bit narrow).
New version: Added versions that cover the entire height of the spacer, so it's no longer required to lock it with glue. There's a choice out of a centered one, one that sits at the bottom, and one that goes at the top.
Remodeled the original STL using Blender
