I have an oval Directv dish with 4 outputs (im not sure what the official name of the dish is called, but it was installed about 18 months ago) One of the outputs are run directly to a receiver in the garage and the other 3 outputs are run into the house. The DTV technician originally connected the three outputs in the house to a Zinwell 6x8 switch, but some HD channels werent working. After some research, I found out that the Zinwell 6x8 switch will not work correctly if less than 4 leads from the dish are connected. Is there a switch out there which will work with only 3 inputs from the dish? I really hope there is a 3x switch, because its not an easy task to run a 4th lead into the house and then an output from the switch in the house back outside and over to the garage. Thank you for any info you have!
