Horizontal polarization intensity fits for the measurements of the prototype horn. Upper left: 10–20 dB attenuation angles values in different frequencies. Upper right: 10–20 dB attenuation angles × frequency. Lower left: attenuation angles absolute values. Lower right: 10–20 dB weighted attenuation angles × frequency. Minimum and maximum values are quoted in relation to maximum beam intensity for each frequency.
