thingiverse

Remix (Sort of) of my project at - https://www.thingiverse.com/thing:6386300 This is the SMA Female version. This is good for radios like the UV5R, and other HT Radios that have a SMA Male port on the radio.Get the BNC Female side preparedSand down the end of the nitinol. I used a dremel like device from the Freight of Harbors.fill up the BNC Female side with Solder (This version uses this connector - https://amzn.to/3vf5r6z - This is an affiliate link) - , as soon as you remove the iron , push in the nitinol Add more heat or solder if needed. Give it a few moments to cool.After it's soldered in place, and you've ensured you didn't short out your outer and inner shield, add 3/64" heat shrink I went with red because it adds 12 Db (This is a joke) Heat Shrink Tubing - https://amzn.to/3v7XBM5 (Also an affiliate link).After heat shrink is applied, drill a hole in the center of the cover I made for the Nitinol to go through. I still recommend 1mm nitinol.6 Confirm everything is functional.7 If it is, super glue the cover to the connector.Sanding the Nitinol down Right before it's ready to go into the connector is critical. This stuff oxidizes fast.
