I'm a fairly new DTV installer and have been asked more than once by customer's ,if I could mirror a receiver so they could use 1 receiver to operate 2 TVs.I've never done this but know that it is done and DTV even puts it on the WO sometimes.All I know is it involves 2 diplexers and a hi-freq splitter.Does anyone know the procedure for mirroring?Please be specific as the ol gray matter doesn't function as well as it did in my younger years.
