The Igloo service was provided through DVB-T and was available in areas of New Zealand where Freeview's terrestrial service is available. Customers required an Igloo set top box and UHF aerial to use the Igloo service. Unlike Sky Digital and Sky 's former UHF service customers purchased their decoder from a retailer and the customer owned the equipment, the customer was also responsible for the installation of the equipment including the UHF aerial. Sky subscribers do not own their Sky decoders and are required to return the decoder on cancellation of their service, Sky will also arrange for a technician to install any equipment in the customers home including the satellite dish.
