Ok here it is. I am hooking up a 2nd tv in my garage using the Home Distribution port on the rear of the 622. I then am using diplexers to send the 2nd tv connection to my data panel in the basement where it is then connected to a dedicated cable going to the garage. When using OTA/Cable and tuning to the programmed channel on the second tv I get nothing but snow. I have tested the diplexers next to the VIP 622 and connected to the 2nd tv used in the garage with no problems but when I move the 2nd TV to the garage and hook it up I get nothing. The total cable run is about 125 - 135 ft. Is is possible that I need a amplifier? I know that the run going to the garage is good since I just recently disconnected standard cable from it. I appreciate the help in advance.
