L = inductance (nH) N = windings D = average coil diameter (cm) H = coil length (cm) C = thickness of the wirelayers (all together, in cm) K = correction factor depending on H/C ratio : L/C K 2 0.10

I will use the 'fat' coil formula because with my coil D = 60cm and H = 18.2cm I don't understand the L^2 in the formula because L is what I am trying to find. A misprint for N, which doesn't appear

Hi Rik L = inductance (nH) N = windings D = average coil diameter (cm) H = coil length (cm) C = thickness of the wirelayers (all together, in cm) K = correction factor depending on H/C ratio : L/C K

Hello Peter, I got 2 formulae from 'Grundlagen der Hochfrequenztechnik' : 1. For 'slim' coils (H>>D) : L = 2*Pi*N^2*D(3.47/(1+2.2*H/D)-K*C/H) where L = inductance (nH) N = windings D = average coil d

I am dismantling a Decca loading coil with the objective of rebuilding it to load my 16m high antenna. It will be converted so that it is a multi-layer coil. Does anyone know of a formula for multila

Dear all. I've just heard from Harry G3MFW who is near St Austell in Cornwall. He is almost ready to come on 136kHz using a Decca TX so we should hear him OK. He also has some of those lovely Decca L
