Any RF experts out there?
Does the antenna that is included with the Cellular Radio module require a ground plane?
It looks like if it is attached to the circuit board it would have a ground plane. However, I have mine going through the side of a plastic enclosure. I get very unreliable connections. Using a small mag mount antenna makes a big difference. Maybe its just the quality of the antenna and that it can be mounted higher. I’m just scratching for some answers.
