For all the three new houses that I have built a key consideration was the TV aerial.
Even though all the builders wouldn’t actually install the aerial I got them to install the wiring to various points around the house with an amplifier in the roof. (If this is what you plan make sure there is a double power point in the roof space)
With my current unit there is no aerial as everything comes through cable, or the internet.
Talking with my friends I find some of them don’t watch free to air stations at all, and many only watch them through Foxtel.
Will you need an aerial on your new house?
