Bill, that notch looks to me like a cancellation notch, probably centered on the frequency where the internal path length is 1 wavelength long such that the backwave emerges from the line terminus 180 degrees out of phase with the frontwave. I would guess the Druids have an underdamped line roughly 85-90 inches long.This guess based on my own experiments back in the 80's.
