I have one transmitter and two receivers which will reliably send an SD video signal from one end of a house to the other end. Complete with all cables and power supplies etc.
We used it to send our Sky signal to two other TVs in other parts of the house. The Sky remote signal can be sent back to the Sky box to remotely change channel etc from the other rooms. Worked fine from upstairs TV room to kitchen below and to bedroom in basement two floors down.
Please PM me if any interest. Can be picked up from Mairangi Bay, Auckland North Shore or I could mail. Looking for say $40 picked up or $50 mailed.
