Where can I find a list of approved - compatible LPWAN antennae for the nRF9151?

I am working on a project based around the nRF9151, particularly its LTE Cellular IoT cababilities. I recently spoke with a consultant regarding the process for FCC / ISED emissions testing and certification, and was informed that in order for our device to 'inherit' the Modems certifications, we MUST use an antenna which has been approved and deemed compatible by the modem manufacturer. 

Could someone please provide me with a resource listing the compatible / approved LPWAN LTE antennae that are compatible with the nRF9151? 

We are currently in the experimental and prototyping phase, and thus I would like to know what options we have for antenna selection so that I may purchase and experiment with a variety of them. 

Thank you
