The question is how an Isotron or Hamstick over the same ground system
would compare to an unmatched/untuned 43 foot vertical on 80 and 160
meters.
It is not the efficiency of the radiator, but the efficiency of the
entire system that matters. Even the most efficient radiator will
be a dud if the system has 20 dB of loss due to high SWR on the feed
line.
