@alex28 yes exactly, it may look exagerated but this is how it works. Same if you would replace the original wifi antenna on a commercial product. Like I said many times above, development boards (like OP design) can maybe fit in the "subassemblies" group, so mostly for development purposes only. CE is less strict regarding the process.
That's a while I looked at this, way before debating..Personally, I completely don't mind what people do, that's not my business. I just mentioned regulations as infos for those who are interested to know more. that's all.
