The question was asked about determining resonance of elements that are not
"split". What I do, is "split em" to do a normal R/X measurement as a
radiating dipole and then connect a shorting wire after the measurement and
tuning to make them as design intended. Way Way easier than farting around
with a grid dip meter. And if the consistency of a long rigid element is
necessary, then use a "one size up" sleeve of Al and run a couple of bolts
through it to re-establish a rigid element. For accuracy, make your split
gap very small (1/4 inch) and make sure your connection is either right at
the element or a half wave multiple away if using feed line (which is often
the case to get something up in the air enough to de-couple from ground).
