CM4 has an internal WiFi antenna on the PCB with a socket for an external rubber duck antenna. It is FCC approved for use with either. I want to use a behind front glass antenna from you for a metal cased display unit with a 7" TFT behind a glass window. Would that need to be retested for certification? Is this something you can help with?
