How do I know which transmitter my aerial should be pointed to for best reception?
To check, you can download coverage maps for each transmitter to see where they are in your city as well as which direction will work best for your UHF aerial.
There are multiple digital transmitters in areas like Auckland and Wellington so there may be a more suitable direction for your aerial to pick up better coverage, always go for the nearest transmitter with the least amount of obstructions, such as large body of water, hills, or tall trees, between that and your aerial.
If you’re on the fringe of good coverage, it’s best to consult an aerial technician or installer to position the right type of UHF aerial for you. You can use this installer directory to find technicians in your area and get an estimate for the costs involved.
