Below is a graph of the typical calculated Reflectivity performance of the satellite pane VS a standard double - glazed glass pane.  0 on the left scale indicates total reflectivity as compared to a metal plate.  Lower on the chart is better.  In the frequency band of 12 - 13 GHz, the standard pane is almost totally reflective, while the satellite pane is tuned to be least reflective in that range (-25 dB).     Below is a graph of the typical calculated Transmission Loss of the satellite pane VS a standard double - glazed glass pane.  0 on the left scale indicates no loss.  Higher on the chart is better.  In the frequency band of 12 - 13 GHz, the standard pane has a loss of over 10 dB, while the satellite pane has a loss of less than .1 dB
