AstroX J5 frame JohnnyFPV antenna GPS Xiaomi Yi mount

Hi friend. These are the mounts for a famous quadcopter frame. They have been thoroughly tested and work seamlessly with my Aliexpress clone. I flew at least 1 km away without excessive video noise. I got around 13 satellites and the GPS rescue function worked flawlessly every time. The required diameter of standoff for each mount is noted in the file name. The tall SMA protrusions are designed to contain the lengthy electrode of MMCX-SMA pigtail, thus relieving strain and making wiring easier. It also helps with long-range flight and improves RF performance compared to shorter ones. The GPS mount may look big but does not interfere with props even during a crash. BN-220 is self-locked in place without any adhesive once the connector is installed. The diameter of small antenna holes except SMA are 3 mm, and they are intended for use with 3mm-diameter protective plastic tubing. I tested 3mmD teflon tubing successfully. Now I just left them empty as I use a Crossfire Immortal T antenna instead. I designed the antenna mounts in such a way that you can pass-through your XT60 connector between the top-plate and the antenna mounts, making it easy to plug your battery. I recommend printing the Yi mount at 103% scale due to shrinkage.
