How to use diplexers?

[EZnow]

Brand new to FTA. I understand that I can combine the FTA signal with the Cable TV signal using just 1 coax cable and 2 diplexers. Can anyone tell me where to place these diplexers? Better yet how can I achieve this installation? All I know is that 1 diplexer is at the LNB but where does the other go? There is a Time Warner Cable TV box, the Viewsat Ultra receiver, and the TV itself. Do I need any other equipment? I would install another coax but it is not possible.

Here is a general picture on how they are hooked up.

I would suggest you get the FTA equipment working 100% before inserting diplexers into the line.
Nobody in their right mind will help you debug an FTA problem with those connected. -

Shop around for diplexers - they vary in price and quality.

I would not advise using diplexers on runs longer than 50 feet (maybe 75 feet max), since they induce losses at both ends...
