Australia is switching to complete digital broadcasting soon. It is getting rid of the analog signal starting next year and that is why there is a scramble for digital set top boxes and a huge demand for digital screens.
For ordinary people, catching this TV signal involves attaching an ordinary antennae to a digital set top box and then connecting this small device to the RF connection at the back of the TV.
Unfortunately, we live in a flat and the landlord has not provided any of the tenants an antennae. We only have this one antenna and we do our best to help it catch the signal. We will probably buy a new antennae.
Ironically, the brand name of our new set top box is Bush.
