Can anybody recommend a decent folding GPS antenna mount, one that's solid and has minmal (if any) vibration? The DJI one is OK but I need one that will fold absolutely horizontally and not at a small upward angle when folded down so that it goes in the case I bought nicely.
+1 on that mount. I got mine from an overseas vendor but it is exactly the same and I am very happy with it. It is also very easy to shorten the mast with a dremel if you need to.
