I just bought this on Amazon:
Amazon.com: 2017 REXUAV - DJI, 3DR Solo 2.4GHz CP Long Range Antenna V4: Computers & Accessories
It's made out of pure silver and has true 9.5db gain. The RX and TX are polarized in opposite directions which will make for good separation, perfect for amplifying both sides. There is no mount for the Mavic. I think I'll make one out of some old tablet holder parts. This type of antenna should give better penetration than the panel type and better for amplifying the RX side.
Edit: Apparently I bought the one that is NOT pure silver by mistake. Hmmm, is it worth $50 to upgrade to pure silver?
