This application provides the ability to compute the performance (aka 'figure of merit') of a parabolic reflector antenna. To use this app you will need to measure the noise produced (dB above cold sky noise) by the Sun at the desired radio frequency. To compute results please enter: Antenna Site location; Antenna ID; Antenna Size; Antenna configuration; Polarization of test; Frequency of test; and Antenna elevation. The application will then go and automatically get the most current solar flux to calculate the results. The application then computes the results and stores multiple result runs in a log that can be emailed to yourself or others.
