yes you can connect any modern analogue or digital receiver, since the LNB on the Sky dish is a universal type.
Bear in mind though that the dish will have been set up to point at the particular position (28.2 east) that Sky Digital broadcasts from, and aside from a tiny number of Czech channels transmitting from an almost co-located satellite at 28.5 east, there is nothing up there that the digibox alone can not receive anyway.
And if you intend to reposition the dish to a different satellite for use with a different receiver, remember that the dish is tiny - just big enough to receive the very strong signals from 28.2e but too small for the weaker signals from most other sats.
