Questions on using existing wiring for a 322 box.

[CPeanutG]

I want to buy a 322, hook Satellite input #1 and #2 up to the third satellite wire that the installer left free for my future use. The other two are hooked up to inputs 1 and 2 on a 722 and a 625

I was reading this Tech Portal : 322 But I don't have two wires coming off the Dish to use for the 322. I just have one.

I know I would have to split the third wire once for the two inputs on the 322. How would I backfeed the TV2 output and use the existing wiring for TV2 which starts where the third free output is?

I tried to draw it out and I ended up using 3 of those splitters. That can't possibly be right.

Take a look at this diagram. You will need a DP separator to use a single cable for a dual tuner.

You need 2 diplexors and a DP Seperator. You have it drawn correctly.

Basically you will have the line in from the dish into the SAT side of the first diplexor and the line out to TV2 in the AV/ ANT side of the diplexor. The in/out side will then run to the 322 location and go into the in/out side of another diplexor. The SAT side of that displexor will feed the DP Seperator to give you inputs for #1 and #2. The AV/ANT side will have a cable from the TV2 output of the 322.

Yeah thats basically what I drew up in my diagram.

The black boxes are these things: http://www.prosatellitesupply.com/images/Separator_DPP-2.jpg

What Diplexors would best satisfy Dish Network techs? Where can I get them?
