If you're tuned into Freeview through a satellite dish and experience reception issues in certain parts of the day, it's likely that your satellite dish is not properly aligned, or is damaged. 

This is because a damaged or misaligned dish is much more susceptible to the minor variations in signal coming from the old satellite as it nears the end of its life. On mainland New Zealand, a satellite dish setup in good working order is not affected by these minor signal variations and would continue to deliver good TV reception (as is the case for most Freeview satellite viewers).

Please see here for more information and what you can do if you are experiencing daily issues with your satellite reception.
