10.7-12.75 GHz
Ku band satellite
Free-to-air satellite television, reached through a dish and a universal LNB that brings the band down to 950-2150 MHz on the coax.
The geostationary arc is full of DVB-S2 transponders, many of them in the clear: public broadcasters, contribution feeds from outside broadcasts, and services nobody put in a channel list. A universal LNB converts the Ku band to an intermediate frequency a HackRF or LimeSDR tunes directly, with 9.75 or 10.6 GHz subtracted depending on the half of the band it is switched to.
The LNB needs 13 or 18 volts up the coax, which the radios do not supply, so a satellite power inserter goes between them and keeps the voltage off the radio. The pointing window says where to aim the dish and how far to twist the LNB for a satellite from your station.
