Spektrum DX8 Antenna Upgrade Collar

thingiverse

This is a simple adapter designed to make upgrading the antenna on the Spektrum DX8 (first generation) easier. The stock antenna is quite small and not quick-release, so this adapter allows you to install an U.fl to RP-SMA pigtail. Instructions: Open the radio and set aside the back. Remove the whole antenna assembly including TX module - it's clear how to do this, so I won't go into details here. Remove the stock antenna and cable from the cylindrical plastic housing. Take out all washers and nuts from the RP-SMA connector of your new pigtail. Insert the new pigtail through the printed component, making sure the RP-SMA connector sits down fully in the hex recess. Use some CA/superglue to fix the cap part over the top of the threaded section of the RP-SMA connector. Re-install the lock washer, spring washer and hex nut over the top of the cap that you just glued down. Tighten firmly but not too much. Insert the assembly into the cylindrical housing fully, then rotate it to lock - this is the same mechanism that holds the stock antenna in place, and I've replicated it exactly on this model for ease of installation. Use a 12mm spanner if needed to lock into place - I've added some flats for this purpose. Thread the U.fl connector through the original metal plate and screw back on exactly as it was originally. Route the pigtail under where the TX module sits. Plug the TX module back in and screw down. Plug in the U.fl connector to the TX module and re-assemble radio cover. Done!
