The Electow ThinkNode M1 is a great radio, but the stock antenna is poor, and flexible replacements put strain on the PCB mounted SMA antenna connector. These are two FreeCAD designs for supports that screw onto the connector both reducing water ingress (like the stock stubby antenna), and reduce strain on the PCB.
The first is for RP-SMA antennas that just screw on.
As these are harder to find (ask me how I know...), the second takes a common RP-SMA adapter (the gold ones). Slide it in the top, and use the brace to screw the adapter onto the radio tightly. This will lock the top connector, to a SMA antenna will simply screw in.
Both designs come with the FreeCAD designs to allow tweaks if your antenna base is different.
