Go near the equator and look at where satellite dishes are pointed. They're not typically straight up, they tend to be pointed pretty far east/west depending on where you are exactly.
Most countries don't have their own satellites specifically in line with them, they're often all using the same ones.
If you're pointing a static satellite dish and expecting constant connection, that's a geostationary satellite. East and west is still an equatorial ring
