/diy/ - Do It Yourself

I'm considering doing an antenna mod on my Taranis QX7. I have heard that cutting the coax cable that connects the PCB to the antenna to a specific wavelength/fraction of a wavelength for 2.4ghz will increase range. Does anyone have any experience with this?

I want to add this little UFL/SMA adapter https://www.banggood.com/IPEX-to-SMARP-SMA-Female-Adapter-Extend-Cable-Connetor-10cm-p-1193797.html?rmmds=search&cur_warehouse=CN

and this antenna

I have seen youtube videos where the controller has a UFL/IPEX joint already soldered in and some without. My controller is relatively new, so I'm hoping it has the joint (I travel a shit ton for work and don't get to check for a few weeks).
