It takes a significant fraction of a quarter wavelength to make a really
noticeable change in the impedance. At maybe 5/8" of mismatched section,
50 pairs makes almost 32", might be noticeable on 10 meters, but not on
80 meters.

Last I looked HP was still making a Q meter, didn't look like my Boonton
170 or 260, but gives the same results. Also a vector impedance meter
and a component meter. Still the results can be had in inductance and Q
because commercial RF coils are still specified by inductance and Q.
Which is important because coil Q is important to the design of filters
and the low Q of today's tiny coils makes it hard to design narrow band
filters that don't have excessive transmission losses.
