Maybe part of the myth is that the antenna must be resonant to work. Nothing could be further from the truth. Has the radiator current distribution changed? No. Does the inductor in the L-network "make up" some number of electrical degrees in the radiator? Not from my viewpoint. I think there are two problems: 1.) Cecil wants everyone to start using reflection wave models to analyze every antenna system in the world. 2.) Many people think a very short monopole antenna that is resonant is still 90 electrical degrees long, and that the inductor makes up the missing number of degrees, and the current taper across that inductor is some form of sine shaped curve. Cecil is free to use whatever tools he likes. He doesn't work for me, and (thank God) I don't have to work for him! What he wants me or others to do is a moot point. I am concerned about the commonly held but very incorrect view that current travels through an inductor turn-by-turn, and that a loading inductor somehow shifts the phase of and/or level of current to "make up for missing degrees". My only concern is people not understanding how an inductor and short antenna actually behaves. That problem is worth attention. 73 Tom |
