QUESTION

asked by
Raspberry Pi CM4 is FCC approved for Wifi - would I need to retest to use with another external antenna from yourselves?
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?

Dear customer -

Can I get which of Antenva's external antennas you are enquiring for the use ?  It's better to know part number or model name.

Possibly Asper or Dromus (We also need to Rx GPS) The issue is that we have the edge of the TFT display cover glass that would fit these but the glass fits back into a cast aluminium frame. We can provide a 2 - 4 mm airgap behind the antennat before the insulated metal frame. I see that some antennas appear to include their own ground plane on the reverse of the sticky patch so I wondered if that would be ok with the back of the antenna being near the metal case?

Thanks for further feedback.

The request look more like technical review on antenna placement and detuning factors. To make the process easier, I would suggest you could contact techsupport@antenova.com to get in touch with your regional representative who will help you with what you need.
