How to Evaluate Beamwidth of Reflector?

Beamwidth of Reflector evaluator uses Beamwidth = (70*Wavelength)/Parabolic Reflector Diameter to evaluate the Beamwidth, The Beamwidth of Reflector formula is defined as the angular width of the main lobe of a directional antenna's radiation pattern. It is a measure of how wide or narrow the antenna's beam is. The beamwidth determines the coverage area and the concentration of the antenna's radiation in a particular direction. Beamwidth is denoted by ψ symbol.
