I have a Dish 500 Quad LNBF which services 3 receivers (522, 811, 811). The 522 is currently connected to two lines and is diplexed or separated not sure which for distribution to whole house.

Just purchased a 921. Need to hook it up. I have a whole house distribution center in the basement which everything runs through with two cable ports in each room. I want to minimize running of additonal cables and use what is existing. I want to connect my OFA for distribution to the two 811s and the 921.

What exactly do I need? I'm confused about swithes, diplexers, and separators especially with the DishPro products.

I'm thinking that I could use a DP21 and connect one satellite cable to the port and the OFA to the other port. Then use a separator at the room to connect to the 921. And then diplex one of the 921 inputs for the OFA input.

I'm thinking an additional DP21 to connect one satellite cable to the port and the OFA to the other port. Then use a separator at the distribution center to connect to the each of the 811 outputs. Then in each room where the 811s are located, use a diplexer and connect one to sat input and one to OFA input.

Does this sound right?

sat input ===>
OFA input ===> DP21 -----existing cable run---->
>-------------------> separator ------>
-from separator---->921 tuner 1
-from separator----> diplexer -------->
-from diplexer----->921 tuner 2
-from diplexer-----> 921 OFA

sat input ===>
OFA input ===> DP21 --> separator ---existing cable run------>
(below repeated twice for each 811)
>--------------------> diplexer ---->
-from diplexer------>811
-from diplexer------>OFA

522 connection remains untouched using existing 2 cable input

Items to purchase:
2 - DP21
2 - DP approved separator
3 - diplexer
