I think that it will be difficult to see conclusive results. Note that
even in the calibration procedure, a slight movement of the connection
wires up or down will change the measurement. This can actually be
useful,
because you can search for a notch.
Maybe better to make the connections through a coaxial cable, at one
side only. At least avoids interference caused by the fields around
the connection wires, specially if you use very high frequencies in
the measurements.
