One would expect that the amount of "detuning" would be related to the
overall "Q" of the antenna.  Antenna designs with critical element
tuning - particularly DE/D1 - will detune more than designs optimized
for lower frequency sensitivity (OWA, log-cell, etc.).

The KLM/M2 designs have always been rather "fiddly" when it comes to
tuning/SWR - specially when compared to some newer designs like the
OWA, LFA, etc.
