My Granny needs a Freeview HD installed antenna for her unit (one-story shoebox). She's in Auckland on the North Shore. Very simple job really. There's already a mast. Just need VHF removed, UHF mounted and directed. Possibly run a new line (short, and external by necessity).

Can anyone recommend an decent installer?

Someone NOT like the muppets who installed my other Gran's antennas: They ran their wiring draped over the roof and through the gutter, even though there was an easy access loft that would have been a more direct route. And unbeknownst to us at the time, they broke a roof tile pretty much in half, then glued it back together with Selleys All Clear. A couple of years later, sitting looking out of her lounge window on a rainy day: "Why is there water pissing out from under the eaves?" Wooden soffit rotted all to hell...
