Do u think this method works fine?

to know the value of inductor used to block 90Mhz signal ,basically one can start the value of choke by 5uH or 1uH and take a RF detector,at connect the probe on the other side of the RF choke to check whether the RF signals are still flowing,if it flowing through the choke ,one can increase the value of the choke ,and gradually one can easily get a perfect value when the RF detector doesent show any RF signal ping the RF choke ,do u think it works.
