another DP44 ?

[DishDave]

I have my Sat. Feed plus cable feed on the same line using a diplexer. Will i be able to use the feed coming of my diplexer sat out to the input of the dp44
then to my new 721?

Whoa...

The DP44 connects 4 satellites. You're looking to connect satellite, off air, and cable. totally different (and possibly cheaper) solution.

You'll need to look for something that can combine your cable and off air together, then diplex it into your cable line.

What that is, I'll have to punt.
