In the situation you mention, as long as the antenna is of the same or lesser gain and also of the same type as approved, then the device can be used based on its approval and would not mandate any further testing when placed in a system. However, approval status only shows an assumption of compliance, they do not show each situation is compliant. We should never confuse a ‘claim’ of compliance with actual compliance of each device to the rules. Part 15 devices, regardless of approval status, always are subject to the condition that they do not cause interference. This basically means that the part 15C device could be fully compliant to the limits in the rules yet, if it causes interference and a complaint is received, it would have to be either turned off or fixed to stop interfering. Failure to do so could lead to fines or other punitive actions imposed by the FCC – again, regardless of approval status
For this reason alone, regardless of no mandated test requirements, it is always a good idea to test the system to make sure that all devices work together in a compliant fashion. That way, if complaints do arise, you will at least have evidence of due diligence.
