All the transmitters on a single site will be within one group and all have the same polarisation. In other words each site will have either TEN, ABC, SBS, Seven, Nine and an unallocated channel for metro areas and for regionals ABC, SBS, TEN affilliate, Seven affiliate, Nine affiliate and an unallocated channel.
I hope that there will only be the following antennas available
As far as I am aware Australia is the only place to use consecutive channel allocation. This is not done in the UK.
For horizontal polarisation
One each Yagi-Uda antenna for each group of channels. Low gain
One each Yagi-Uda antenna for each group of channels High gain
One each phased array antenna or each group of channels High gain
For Vertical polarisation
One each phased antenna for each group of channels. Low gain
One each phased array antenna for each group of channels High gain
One each Yagi-Uda antenna or each group of channels High gain
The only area where there is some doubt are Sunshine Coast, Gold Coast Qld and Central Coast NSW. These areas are big enough to have their own unique feeds of commercial stations.
I hope that all other antennas are removed from the market. The example now is that antennas designed to receive channels below channel 6 are still being installed which is a rip off of consumers now. The manufacturers, wholesalers and retailers should remove all of these antennas from the market.
