Question ID: 120971
I have a dish network satelite system.  It has 4 lines coming from the
LNB.  I would like to take one of these lines and put a splitter in
it.  Dish network said you cannot split the line like cable.  Is this
true?  If not where can I get a splitter?  I also have a PVR 508 and
it has an expansion port on the back.  It looks like a SCSI port. 
What is this used for and can I get software to acces this,

Hello greenuglyogre-ga

It would be strange if you could not split the line. 
You can either split it to go to multiple receivers so you can watch
different channels at the same time. Or you can split it after it
comes out of the receiver to share the same channel with multiple TVs.

Splitting is mentioned in Dish Network's FAQ section, point 10 last
sentence in paragraph:
"How do I install two or more receivers?...
Answer: The ability to operate more than one television independently
through DISH Network satellite TV system will require a dual LNBF
system, which is capable of connecting the dish antenna to up to five
independent receivers. The price of a dual LNBF system begins at $199
(depending on the model). Then you may add an additional receiver
(either IR or UHF) starting at $99 per additional receiver to add to
your other TVs. The additional receiver will allow the duplication of
your programming by a separate satellite TV signal being sent to your
other TVs, so they can work independently. The cost of programming for
each additional receiver is only $4.99/month. Of course, you can hook
up as many TVs as you like to just one receiver, but they will receive
the same programming on all TVs. More than two receivers require a
voltage line splitter and a dual LNBF."
Excerpt from Dish Network's FAQ "Single-Dish-Antenna Questions" sell splitters for Dish Network, which is strange isn't
it ;-) ?
"Dish Network Installation Accessories"
and feature a 2 way and 3 way splitter.

Also show how to combine Dish Networks and DirecTV
satellite reception
Note the wiring diagram which shows the use of two splitters to
provide two extra outputs.
This setup connects 4 Dish Network receivers and 4 DirecTV receivers.
The instructions continue to the next section
where they recommend the type of splitter
"You will need two satellite-grade splitters for the project.  Make
sure you do not use those intended for Cable TV, as they will not
work.  Also, the splitters you get have to be designed to pass DC
power only on one leg of the split, as seen in the picture.  Most of
them are not like this.  I got mine from "

This probably explains the response you got from Dish Network, a cable
TV splitter will not work.
The splitter featured by the installation is the
Centronics STV1782B:
Here is an alternative 2 ghz satellite splitter with dual DC powerpass
from sell similar accessories
Ultimately I guess it depends on your receiving equipment if it needs
a single or dual powerpass.

The PVR 508 expansion port ( )
Second sentence, first paragraph of SkyVision's webpage highlighting
the PVR 508's capabilities says:
"An expansion port allows the 508 to be upgraded for additional
recording capabilities."'s information on the 508 states: "Expansion Port
- allows Pro 508 to be upgraded using future products being designed
to allow increased recording capacity and possible interface with
other peripherals for the ultimate in entertainment choice."
It appears this port has been provided for future expansion with no
current accessory or purpose, so if any feature needs to be added via
this port it can.

Search Strategy:
splitting OR splitter satellite line
"pvr 508" expansion port
508 "expansion port" dish
Satellite RF Combiner/Splitter 
cable distribution tvs
"dish network" splitting OR splitter
satellite distribution

I hope that helps, if you need any clarification of the answer just

Kind regards

Hi Guys,

Great information!  One question though.  I have have two DishNetwork
Satellite dishes (2 Dish 500's, the second is for internatinal).  When
the installer came, he combined the signals from the three heads into
two lines.  It is these two lines that enter my house.  I would like
to split the signal so that I have the possiblility of using a
receiver in my basement.  I already am using the two lines  in the
rest of the house.   How do I split one of these lines if all of hte
signals have already been combined?
