If Mt Canobolas is blocked
Hills and tall buildings can block the first choice. These are the next best transmitters for Portland:
- West Wallsend: 71° ENE, 154 km, horizontal, UHF. Expected signal: fair.
- Knights Hill: 155° SSE, 155 km, horizontal, UHF. Expected signal: fair.
There is also a low-power local transmitter at Garlands Hill, 211° SSW, 6.2 km away, carrying 5 channels. Local transmitters fill in reception holes, so if your street sits in one, aim here instead. It often uses a different polarisation, so check the channel list on your TV after retuning.
How to line it up
Stand where the antenna is going, hold your phone flat and open Compass. Turn until it reads 271°, then aim the front of the antenna that way. The iPhone Compass app uses true north by default, which is what these bearings use.
Bearings and signal estimates come from each transmitter's licensed power and distance. They do not account for terrain, so treat them as the starting point. The government's mySwitch tool can check an exact street address.
Aerial Pointer shows a live compass that turns you onto the transmitter, ranks every option for your exact spot and works with no signal.
