Yes you can position them anywhere, but the point is that it has to be at
the equator.
Obviously if the position was so low in the sky from the uk that it was
occulted by the land or buildings, its not going to work well and you would
be unlikely to be in its coverage area for any of the beams sent to earth or
receiving from it unless the programme material was uplinked from here.

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, as long as it still rotates in a line
parallel to the equator and rotates around the earth at the same rate as
the earth spins? Or would there be a nett force dragging it towards the
nearer of the two poles - is the equator the only place for geostationary
because there is no nett force towards either pole?
