When making the signal strength measurements using a loop antenna should
this be resonated or aperiodic?

A resonated loop produces more signal but has to be calibrated by means of a pair of Helmholtz coils.
The voltage induced in an aperiodic loop follows from a simple formula, that can be found in Terman.
So there is no need for calibration when the loop is used with a selective level meter.
