Armattan Tadpole Crossfire Immortal L Antenna Mount

This is a small mount for the Armattan Tadpole 3" intended to hold a stock TBS Crossfire dipole antenna at a 120 degree bend. Inspiration credit obviously goes to Mr. Steele.

While this is definitely less efficient than a straight dipole would be, a 120 degree bend seems to provide a decent radiation pattern according to this article on qsl.net. Realistically, this a 3" freestyle quad -- it has more than enough range to spare for a more convenient mounting method at 900MHz. Within a couple of hundred meters, I'm maintaining ~70 LQ even with multiple metal obstructions and dropping below the horizon of my goggles. With any sort of altitude or line of sight, it's easily maintaining >90 LQ.

Remove supports.

Feed the active and passive antenna elements through the mount. The channel for the RX wire has a small cut out to snap it into place after the elements are inserted.

Slide ~2.5mm wide zip ties into the channels with the antenna elements. Trim the zip ties to length and use heat shrink tubing to secure the elements to the zip ties. .

Insert the mount into the left side of the rear cage and use another zip tie to secure it in place. There should be a millimeter or two of clearance between the mount and the prop.
