This is a highly regarded C and Ku band Universal LNBF that has been out for a year now.
It switches between C and Ku with diseqc. It switches polarity with voltage. It switches
Ku LO frequencies with 22 kHz.
The 8920 spec claims support for all of these signaling methods.
But how to get Dream or Blaze to understand a device with both
C and Ku bands, and emit the proper signals???
