FlySky Noble Antenna Adapter

thingiverse

I am using the Flysky Noble NB4 with my cars and pretty happy with it. But as I am always sitting while driving, I hold the Noble downwards, which means the stock antenna is pointing towards the ground. Usually not a big deal, but sometimes I loose connection and receive a "Signal Lost" warning. Then I saw a video from a guy, disassembling the Noble and it turns out, that the noble has two antenna connectors and the original antenna itself can be changed easily. So I ordered a set of: 2x external 2.4 GHz Antenna with 2 x 12 cm U.FL Mini PCI to RP-SMA Pigtail Adapter 2x SMA Male to Female Right Angle 90-Degree Adapter (optional) After printing the Adapter for the the external antenna, I also designed a cover for the unused RP-SMA connector as well as a cover for the 90 degree Adapter - just to make it look nice. ;) Everything is designed to fit pretty tight. If it is too tight, use some hot air gun to soften the PLA and gently press to fit. I heated up the 90 degrees Adapter a bit with a soldering iron and the press-fit it. Works really good and fits 100%. Important Info: Unfortunately, the two antenna ports does not act in diversity mode (as I was hoping) - at least I could not see any improvement while having two antennas connected... :( In stock setup, only one antenna is connected to the board and the second one is unused. So I ended up using just one antenna as well. Therefore, I added another Adapter with just one Antenna port. This Mod does not convert the Fylsky Noble to a Long Range System, but improves signal quality a bit - at least I do not hear the annoying Alarm beep and the "Signal Lost" warning at certain spots as with the stock antenna. This mod also enables you to try out different other external Antenna setups.. :D Please feel free to post a Make and your experience.
