        correctly).  It is just classic array physics - just big at
        these frequencies.  The physics is the same for the nifty flat
        panel radar arrays or curtain dipole arrays like we use in HF
        broadcasting.  They just have some very cool software to change
        the transmitter exciters to provide beam steering, circular
        polarization, and lots of other cool stuff.  Each dipole has its
        own transmitter.  180 cross dipoles with 360 10 kW
        transmitters.  </font><br>
