The same applies to single layer thin enamel/formvar wire close wound. For
small loading coils in my case on 137 kcs I use 2.5mm with thick plastic
insulation or litz 3mm 726 strand single layer, less than 500uH in my case.
Multi wind is satisfactory for a few hundred volts or low kilowatts but not
megawatts.
