Amen and Ditto! For those interested and willing to immerse in the "war" about the Current Distribution in Antenna Loading Coils, significance on the efficiency of antennas, problems with understandi

Hi, My recommendation wasn't regarding linear loaded elements. It was a drooping element design. Half wave dipole elements, from the center insulator outward the element is 1/8 wave horizontal and 1/

There isn't (or should not be) much disagreement about the current in a coil. Quite simply, unless there is a significant loss - either I^2R or radiation - the current into and out of a coil must be

Joe- I agree, so long as you are covering DC current, but our subject is AC. In your statement about creating or destroying energy, the third condition of storing energy seems to be neglected. The cr
