What is the correct community to ask a question about antenna modules, more specifically, the nRF24L01 wireless module?
I asked a question about the module's transmitter antenna gain and field strength in Arduino Stack Exchange because the module is usually used with Arduino. However, the question was closed because it is judged as off-topic.
Now I wonder where in Stack Exchange (or outside platforms) I should ask the question. I'm guessing Electrical Engineering Community or Physics Community, but I would like to make sure as I would not like to mess up communities and also my heart hurts when my question is closed.
