No, it is just as spectrally efficient as any 256QAM radio... One 80 MHz "low" channel in both polarities and one 80 MHz "high" channel in both polarities, as a typical FDD band plan such as you would use with a configuration with 2 dishes, 2 orthomode transducers and 4 radio heads (each radio operating in a single polarity) in a 2+0 configuration.
You're arriving at the figure of 320 MHz by counting everything twice.
