1. A hybrid scanning antenna comprising:
a reflector having a focal line;
a first mechanical movement to move the reflector about a first axis;
a second mechanical movement to move the reflector about a second axis;
a linear array fixedly disposed along the focal line to electronically scan at a scan angle about a third axis; and
a controller to control the first mechanical movement, the second mechanical movement and the scan angle of the linear array to orient the hybrid scanning antenna to a look angle of a remote transceiver,
wherein the linear array comprises an Rx linear array layer overlapping a Tx linear array and separated by a sub-reflector layer transparent to Tx signals.
