The DreamCatcher 3.0 kit includes the LNB. There is no dish.
LNBs are nowadays inexpensive and mass-produced in China. You won’t need to pay for shipping on that dish. If you want to build a radio telescope, there’s plenty of old C-band dishes waiting for you to maintain. It may be easiest to leave your dish for someone else in Europe. If your LNB is really 5GHz wide, by all means take it with you.
There are basically three different LNB types for Ku-band: Standard, Astra and US DBS.
Standard - Linear polarized and uses the DC supply voltage to change from vertical to horizontal polarization.
Astra - These add a Ku low band. The linear polarization is switched with the DC bias on the coax line but also selects between the two bands with a 22KHz tone superimposed on the DC bias.
US DBS - The two DBS broadcast services, Dish Network and DirecTV, use circular polarization instead of linear polarization. The bias voltage switches between right hand polarization and left hand polarization.
But wait, there’s more…
There is one more consideration - PLL vs DRO.
PLL - Phase Locked Loop
DRO - Dielectric Resonator Oscillator
For a narrow-band signal like Outernet, a PLL LNB was chosen because it’s more frequency stable than the older DRO type.
What does Outernet use?
Outernet, according to @Syed will use a Maverick MK1-PLL LNB. It’s “Standard” and PLL frequency stabilized. Just perfect for LoRa from Geosynchronous orbit.
