> How bad does the big metal thing close to the antenna effects antenna resonance and therefore antenna efficiency?
Not much. I tested it. See
https://cool-web.de/nrf/lora-meshtastic-reichweitentest-lilygo-elecrow-seeed-2025-09-18.htm
And see my "Internals of the T-Echo Plus" - Video (linked in my article) to take a look inside the device. I think, the GPS-Antenna could be positioned better.
