There should never be "legal limit" power level on any transceiver antenna
port. The maximum power level should be the transceiver's transmit power,
and it should only be on the tx/rx port when transmitting. The internal
switching in the transceiver will keep that transmit power out of the
receiver front end. There should never be any RF power other than receive
signal levels from the antenna feeding into any antenna port on a
transceiver.
Perhaps I am misunderstanding your question. How/why would you ever have
legal limit RF power going IN to your transceiver?
