"[It is the same satellite companies like Sky use to broadcast their
TV signal and] they are positioned above the equator to maximise
coverage."

Oh dear! Actually, they are positioned over the equator because that
is the only place you can obtain a geo-stationary orbit, enabling
fixed dishes to work. Satellites that aren't in geo-stationary orbit
require movable dishes that can track an orbit to communicate with
them ...


Could you not have a satellite in a geostationary orbit above another line
of latitude than the equator


No because Earth is a slight doughnut shape with the bulge through
the equator, and the Moon is also orbiting around the equator
which means orbits other than equator are not stationary or stable.
