Hello!
I have a small follow-up question regarding this answer RAK3172 TELEC Certification Antenna info - #2 by beegee and the use of the Blade antenna for certification.
If I need to use your patch antenna in CE/FCC markets, I won’t be able to reuse your certification (even if it has smaller gain)? Is there any module that you certified with the patch antenna?
Best regards,
Romain
Welcome to RAK forum @Rfd .
Reassessment needs to be done if changes are done to the default setup of RAK3172 - circuit board, antenna, etc. Depending on the gravity of change, you might need to do another round of testing for certification. This is something to be consulted to a certification engineer or test labs.
As for module with patch antenna, we do not have one.
Thank you for both the welcome and the answer 
I see! I could only find the certificates in https://downloads.rakwireless.com/#LoRa/RAK3172/Certification/ From what I read in other posts, we must ask you directly if we want the certification reports right? In that case, could I get them please to see the setups you did the certifications on?
Regarding the patch antenna, sorry I might have used the wrong term but my goal is to use your PCB antenna PCB Antenna for LoRa (with an MHF connector) – RAKwireless Store No module has been certified directly with this one on your side?
Best regards
