Coax Cable loss and SWR calculator - This small window application will calculate Coax Cable loss from SWR and SWR from Cable Loss

Meter Mate - SWR Graph Software - Meter Mate is a companion utility for your directional watt meter that allows you to calculate the SWR reading when the forward and reflected power readings are measured. In addition to calculating the antenna system SWR Meter Mate will also plot the SWR curves of all of your antennas onto graphs that may be printed out.

Parabolic - This program calculates geometry, gain, losses, efficiency, directivity pattern and other parameters of primary fed and offset parabolic antennas.

TubeCalc - Input (grid or cathode) and output (plate) tube resistances calculation according to its electrical characteristics, frequency, mechanical dimensions and working conditions.

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
