Just wondering does anyone else find TV1 broadcast from Mt Te Aroha rather weak?
I am using bunny ears to pick up tv reception which I know isn't that great, but from Hamilton I can pick up TV3 and C4 almost perfectly (it comes from Ruru hill), tv2 has some reasonable strength but TV1 is shocking.
We were watching the americas cup last night and lost count how many times I needed to adjust the antenna.
Thanks

The transmitter for TV1 on Te Aroha is quite powerfull and provides service to a large area. With a proper aerial on the roof you would get good reception. Bunny ears don't cut it i'm sorry.

TV1 is transmitted from Te Aroha on VHF channel 1 (44 to 51 MHz) vertically polarised. The wavelength is 6 metres therefore you need an antenna with a dipole that has a width of 3 metres orientated vertically and in line of sight of the transmitter. Somehow I don't think rabbit ears meet  this specification with the length of the rods being more suited to band 3 channels (TV3, C4 in your case).

P.S. You need a VHF Band 1 antenna (vertical) and UHF antenna (horizontal) pointed at Te Aroha + VHF Band 3 (vertical) pointed at Ruru. The UHF antenna will be suitable for the Freeview DVB-T H264 digital terrestrial service to start in March.
