In this case think of the network analyzer as a transmitter with a receiver
tuned to the same frequency. Before testing you connect the two together and
normalize the receiver response to unity at each test frequency. Now connect the
transmitter port to one antenna and the receive port to the other antenna. The
response will be some fraction of unity, which can be presented as %
transmitted, or more often in dB.

Note also that this is a vector NETWORK analyzer. A NETWORK analyzer has input
and output ports, so that in addition to impedance and TDR, it can also measure
the response of any system. You can, for example, measure the effectiveness of
filters, and the coupling between adjacent antennas.
Jim, for those of us who haven’t used a network analyzer, how do you use one to
measure coupling between antennas?
