The antenna on these cheapo modules is bodged anyway. They don't get a good signal out and it's not just because of the size. I have other modules from waveshare that use the same antenna and they work way way better. So yeah I also do this if I really need the WiFi or Bluetooth. Usually I don't though. Edit: oh I see he goes into that later. Like the way they don't leave a copper free space around the antenna. Exactly. They are a bit compromised but they are so so cheap.
