Are you saying the wider the bandwidth, the greater the efficiency? Or are
you saying the the efficiency is inversely depending on bandwidth?
I have never owned an Isotron, but I believe they have a very narrow
bandwidth and have to be tuned, i.e. high Q-narrow bandwidth requiring
retuning for just a small shift in frequency within the band.
