Coil design - PA2MRX
A honeycomb coil is not more then a one layer cilinder coil. Many variations are made of this type of coil. After many tests and research they came to the conclusion that the selfinduction is going through a maximum when the cross section has a rectangular form (Thickness is same as width) like in fig.19 is the same, and when the average diameter is the same is 3x the thicknes of the winding.
