With a series fed vertical on a base insulator, you should be able to
disconnect the antenna, leaving the mast floating (if it is 1/4 wavelength
or less), and compare the noise in the rx antenna. If there is coupling,
the noise should increase when the vertical is connected to the matching
network.
I have tried this with various receiving antennas and could never tell any
difference using A/B comparison.
