gday, im in penrith and lived in a 2 story house, my room was on the bottom and in the corner, no antenna connection, i went to DSE and tried all their portable antennas with amplifiers, none worked for my HD TV.. it sucked cause i just bought it and only thing i could do was watch simpsons on blueray lol, anyways gave jims antenna's a call, charged $100 to run a cable in the roof to the side down the wall and got a plug made up in my room, picture was perfect! then moved out 2 months later :( i then moved into this house now, no antenna in this room either, so i went to bunnings, bought the cables and sockets and splitters, $60 all up, DIY, picture perfect !!
