PNA as pseudo SA

I should know the answer to this, but I'm not sure.  I need to sweep the 5.7 GHz ISM band for signals.  I am going to connect an external antenna directly to a receiver input (bypassing the coupler) and look at input A.  Does this drop the noise floor by the coupling factor?  I realize the values on the screen will not be calibrated, but I don't care about the absolute value.  I have a known signal and I just need to see what else is in the vicinity relative to that.

I would use an SA but I don't have access to one, and I do have access to the PNA.
