Australian TV is undergoing heaps of changes to the effect that we are transmitting a digital signal mainly between 715-840Mhz UHF.all the antennas will he horizontally polarised instead of vertyical and it will still be PAL and not SECAM.
The holders of the old CRT Cathode ray tube TV which is the one bit the picture tube at the back and NOT flat screen TV's will need to purchase a digital set top box which the buyer is then able to plug into their TV and with the assistance of an outside antenna,point it towards the general direction of the transmitting tower and the receiver will receive the TV in digital.
Where I reside has got retransmission TV outputs which are owned and controlled by the local Council and until such time as the Federal Government and also the local Council,get their act together we are forced to watch TV retransmitted from the site on top of the hill at the eastern side of our town.Some residents who live south of the town,can switch their antenna toward the digital output signal and so can many residents that reside west of the town,BUT thoswe whe reside near the mountil are stuffed......
Many residents are using the facilities to upset the Council and to force their hand into providing us with a service before the cutoff point in 2013
Our local town in rural NSW relies on PrimeTV,WinTV,SouthernCross Broadcasting and ABC,in other words Ch7,9,10 & 2
Hope that helps some what
