to the height alone, conventional wisdom says that a short vertical has
the same radiation pattern as a full sise one,and even 300 feet is far
short of full sise. So where do we look  for the explanation? >>

Don't forget that the transmission was a full 1W ERP (from only
10W in!). Very few amateur stations are able to run that amount of
power even with hundreds of watts input.
