<< The performance of the Decca Ant. is quite interesting, the "gain"or at least the advantage over the normal amateur installation appears to be at least 20db.... This is tremendous and I dont see how it can be attributed 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.
