I'm hoping someone out there can tell me what nobody else seems to be able to.

I have just moved to Ahuriri, a suburb of Napier that sits at the bottom of Napier hill, on the opposite side to Mt Erin, where TV signals originate. Fortunately there is a nearby repeater by the HB airport. We receive excellent UHF Freeview signals, for everything but TVHB. I use a Dish set top box that has received HBTV in another location and an LG smart TV that is 2 years old.  I'd be grateful for any ideas.
