Hi all,Ron on tello fb group got 706m off of a stock xiaomi in the country on TelloFPV. He is in US. Posted video. It confirmed that your mod probably isn’t that helpful.
I was shocked when disassembling my Xiaomi external antenna mod for using parts into a new project. I discovered a desoldered antenna wire like this:

This broken wire can explain my mod malfuction and poor results.
Maybe we should give this mod a second chance...
