- HeliCoil
- Inductance calculation for single layer, air-wounded coils and helixes up to about 800 MHz. Inductance calculations accuracy is around 1%. Also, coils with maximum Q for given inductance, resonant RF chokes, PI and T resistive attenuators calculations are provided. Skin effects, radiation losses and other minor side effects are not accounted in maksimum Q factor coils calculations. Program assumes using copper (Cu) enameled or silver (Ag) plated wire. Program is writen bilingual in English and Serbian by YU1AW
