Also some coax cable, a DVB-S tuner and a receiver or a receiver (e.g., ORx Raspberry Pi kit) with integrated DVB-S tuner (e.g., Lighthouse).
Then you would need to find out what satellite you want to tune into, and point the dish that way, and finally connect all the equipment to the LNB using a coax cable. If you’ve never done this before, it’s best to get informed on the web first, or ask someone in your area who already has a working setup.
