WebDoing RF calculations using python and SPLAT This project aims for a specific usecase, means calculation of signal propagation maps which can then be used as overlay on online maps, and doing some specific processing on those generated tiles. This means we call SPLAT in a specific way to return the results as georeferenced image. WebIn order to get the RF parameters of the transmission line, it is necessary to derive the propagation constant of the line. The propagation constant γ of the line is defined in scikit-rf as γ = α + j β where α is the attenuation (in Neper/m) and β = 2 π λ = ω c / VF = ω c ϵ r the phase constant. First, the wavelength in the coaxial cable is
