Just to clarify on this point, I didn't actually say that the 1 turn loop was hopeless (I also know people have tried these and reported good results), just that the calculations (equations) for the radiation resistance of loops vs whips suggested a loop in general would be poor, but as I pointed out those don't take into account the much higher rms current in the conductors which comprise the loop at resonance, compared to the whip (unless the whip drive voltage is very high).
I also pointed out that the radiation resistance of a 5 turn loop is 25 times higher than a 1 turn one (as per the equations), which is obviously a helpful feature, but a 1 turn loop, if a good size could work surprisingly well too, under the right circumstances with good driver.
