The books explained all about how a wire or rod has, along its length things like capacitance/inductance/resistance and how shortening the wire or lengthening it caused changes in the effects.For instance on a full length dipole the ceter feed would be at max amps and lowest volts.etc.I can get this far but how the wire becomes capacative or inductive along its length i cant figure.For weeks ive drawn dozens of sine waves on scraps paper but stiil cant figure it.Ive tried internet but the advisors all seem to assume the reader is a genius. One writer has a book on here 70 pp long and goes into every technicality but,does not explain what i want to know.WHY.Ive tried using a resistance meauring noise bridge that folks claim is dead simple but i cant even understan what the resultant measurements indicate.The bridge dont measure inductance and,even if it did it would be of little use as in would not understand it.The clown who claim its simple the seem to write articles of baffling complexity so what world are they living in,not mine.I think the books earlier ref to have a name inside like kroger or similar.I wish i could find them.Why why why are books in uk impossible to understand compared with usa stuff like this or for instance early tab books which i cant find either.Looking forward to my next life as.could not be worse.Any ideas???Sure what i want to know is vital as a first principle so why this avoidance.
