Bill, Perhaps you could explain to us why coax cable does not allow RF energy to move from the inside surface of the shield to the outside surface if not for skin effect? You would agree that the ins

Just maybe a moot point but if I remember my transmission line math correctly, the center conductor and the shield form the boundary conditions for the wave equation so the RF energy in a coax line i

So if there is skin effect in play inside of the coax why do you think that there is not in a flat plate conducting RF current? 73 Gary k4FMX _______________________________________________ Amps mai

Agreed, Right results, wrong conclusion. The disk, whether aligned with or on the edge adds two things, capacitance and diameter to the radiator. The position makes no difference with either. IOW the

Coaxial cable depends on an electromagnetic field whose end point are on the inside of the shield and the outside of the center conductor. For that matter, it's the same effect that keeps a parallel

Bill, How many times do you want me to quote you saying that "skin effect does not keep RF from flowing thru a plate"? it has been in almost every one of your posts. That is what started this whole

It is analogous to nothing! One is an antenna and the other is a chassis that we were talking about. Very different things going on there. And no, the current still doesn't flow thru the antenna dis
