So I moved the aerial to my LCD TV with Freeview built in. It found 17 channels all with good signal and no interference and no artifacts.
I know the analogue signal is going off next year but I wanted to revive my two older TVs and give the kids the chance to watch normal TV whilst the wife and I hog the big tele and the MySkyHDi for the rugby over the next couple of months.
Before I start thinking about getting someone in and spending $250-$300 to install an aerial are they likely to be able to get a better picture or have they already turned down the power on the analogue signals - particularly considering the strength of the digital signals. The spending freeze also prohibits the possibility of buying set top boxes (maybe in next years budget).
I'm in Waterloo, Lower Hutt and have geographical line of sight to Mt Kaukau although physical line of sight is blocked by two trees around 100mtrs away.
