Antenna Coupling measurement in a noisy environment

Question asked by skymaster on May 13, 2011
Hi all,
I've to measure the mutual coupling among two antennas in FM broadcast band with a network analyzer PNA X. How can I get rid of the signals coming from the repeater and consider only the signals coming from PNA?
I was thinking:
1)Increase the power of the signal coming from pna to put the external signal in the noise floor
2)measure outside left and right not occupied frequencies and then interpolate

something better?
thanks sky
