How do satellite dishes for tv (Direct TV for example) communicate with satellites when there so small and pointed at a small area in the sky?

Thankfully as well. Your dish doesn’t need to send data back, only receive. It can be relatively small, where as the one in space is very powerful and broadcasts over a massive area
