We are using SMA connector in our design.The current antenna that we are using on the EUT does not comply with FCC subpart § 15.203. I would like to know if there is any workaround to get TCB certification without changing the connector itself?
After reading the section you reference the “The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited.” statement is not really something that one can get around.
The recommendation from others is that the connector would need to be swapped.
An option for the RP-SMA item can be the J917-ND
The below link shows all of the options I had found too.
