Dish 500 x2 to 625 - diplexer or not?

[Dishy]

Hello everyone,
Its nice to be a part of this forum rich with so much information and expert advice. Hope someone can help me too to get my Dish going.

I am trying to setup two Dish 500 (each with Twin LNB, I believe dishpro) with 625 DVR (dual receiver).
First Dish to get 119/110 and second to face 61.5 satellite. What should be the simplest wiring?

1) What if I connect one cable from each dish to Sat1 and Sat2 inputs?

2) I bought a diplexer from radioshack but I don't know if I need it or not. If I do, how to connect it?

This is an apartment and physical distance between 625 and dishes is a few fts. Also, I already bought a pair of coax RG6 and in no need to save cables either.

Thanks in advance.

You will need a Dish Pro Plus Twin LNB. A cable from 61.5 goes to the LNB IN on the DPP Twin and a cable goes from the DPP Twin to your 625 separator. The separator will feed both tuners on the 625 receiver.

The Dish Pro Twin LNB will combine 119, 110 and 61.5 on the same cable with its built-in switch.

The diplexers are needed only if you're combining CATV or OTA(UHF/VHF) signals with satellite signals. A Dish Pro separator looks similar to a diplexer or splitter but it's neither. A DP separator will allow you to feed dual tuner receivers with a single cable.

Here's some info and installation diagram for the Dish Pro Plus Twin:

Dish 500 for the 110/119 has a dishpro plus twin, dish 500 for the 61.5 will need a dishpro dual, the coax from the 61.5 lnbf goes to the single stand alone port on the dishpro plus twin, a coax comes out from the dishpro plus twin to a ground block ( please be smart and ground your system properly ) and then on to your 625's seperator then to the receiver itsself.

1) one tuner would get 110/119... the other would get 61.5, which would not work
2) unless adding ota, or backfeeding the tv2 signal, you dont need the diplexer. and if you are adding ota or using it to backfeed, you will need 2 diplexers (diplexers are used in pairs)

as mentioned, get a DPP Twin and a single or dual DP lnb, and you will be much better off

Thanks for your replies, and I apologize, when I looked at the Dish and LNBs closely and read some more information, I found out this is all legacy installation with Dish Network marking not dp.

Now, if I use this diplexer (which a friend of mine believe is an equivalent to SW21) to connect two coax from 119/110 LNBs to make one cable and hook it to Sat1 on 625 AND connect any one cable from other Dish (61.5) straight to Sat2....?

I'll try to sort out this statement.

It's not a diplexer, it's a DP separator and it only works with Dish Pro Plus equipment. Either a Dish Pro Plus Twin or DPP44 switch. If you're using legacy equipment, you will need two cable runs to the 625 receiver and CANNOT use a separator. You will also need to combine the Twin and the Dual LNBs with two SW21 switches.

Save yourself some headaches and just buy a DPP Twin and a DP Dual and you can use the separator and have a single cable run to the receiver.

BTW, Welcome to Satelliteguys!

Your friend is wrong... diplexer, splitter, seperator, sw21 switch.... all VERY different things with VERY different functions

Thanks a bunch to everyone.
