Been following your posts in your other thread. Your not stupid - just trying to learn something new. All of us started with zero knowledge on the subject at one point.

The Amiko Mini HD RE will receive DVB and DVB-S2 FTA (free to air) channels via a ku (small dish) or c band (large dish). It is great receiver for someone starting out and it is sold by a member of Satellite Guys who offers great support and help.

P.S. It does not do 4K but most channels are still DVB/DVB-S2
