Here's a low profile X8R mount that's great for minis.
There is a lot of confusion about the optimal way to mount these antennas. Instead of just having "whiskers" they end in paddles that contain PCBs. These PCBs are supposed to increase performance by something like 20% according to FrySKY.
Here's how you are supposed to mount the antenna:
1) Antennas should be perpendicular to each other
2) Paddles should perpendicular to each other (one paddle up, one paddle flat
3) The antenna wire is part of the antenna so keep it extended and follow #1 above (this design does not meet that criteria but I still get great range)
HOW TO USE
Add some double stick to the paddles, seat them in the holder and use a zip tie to secure.
