The idea of parallel conductors is to lower the Q, space the conductors, and make winding the coil easier. Has anyone recorded tests of this winding compared to a simple winding? I need to know is simply how big the elevated counterpoise should be in meters to be effective but I do not understand how to extrapolate the diameter of and effective counterpois in meters (its size) from the graphs. Please explain use of the graphs for me. J.
