can quectel modems be accidentally damaged without an antenna? (em160 rg502 ecc)
Normally, the module modem will not be damaged if there is no antenna, but if the antenna is not connected, the received network signal will be poor, which will affect the successful registration of the network, thank you.
so if the module enters transmission without antenna, as the reception range bts is very high it could be damaged? or is there a system that controls the antenna load?
Normally, the antenna can only control its impedance to optimize the transmission efficiency of different frequency bands, which is what we call the tunner, and I have not heard of the idea of controlling the antenna load.
