WebThe Beamwidth formula is defined as the points where the power falls to half of the maximum, i.e. the -3dB points on a radiation pattern polar diagram is calculated using Beamwidth = (70* Wavelength)/ Dish Diameter.To calculate Beamwidth, you need Wavelength (λ) & Dish Diameter (d (dish)).With our tool, you need to enter the … WebPrime focus parabolic dish focus, gain and beamwidth calculator for HP41C. Messy stack version by Michael Fletcher, OH2AUE, 1999. Minor cosmetic improvements, 2005 (yes, I am still using this !) G ant = 4 * π * A e /λ 02 A e = h * A A = π * r 2 ΘE (-3dB) = (73 * λ 0 ) / D. A e = effective aperture of dish. h = illumination efficiency.
