The Legend
I use a HD wireless transmitter I got from Miro, was about R 2200 for the two components. With an HDMI splitter, I can watch HDTV upstairs quite easily. My house is a mission to wire up because of the convoluted roof arrangement and layers, so this did the trick.
But if you are building, have the electrician run you conduit where you want it, and get him to put in draw wires, then you and he will know the pipes are free from blockages
Can you link to where you bought the HD transmitter?
