satellite addition

If not the best group to post, please let me know.
I have four rooms with DirecTV. I want to add another receiver to a room. The room is adjacent to another room with a receiver already installed.
Can I simply get a splitter from the one coax to both receivers? Or do I need to add an additional line from the dish?
Thanks !

"They" claim you need a special splitter, but I have used a regular splitter from WallMart and it works fine (without any degradation of the signal).

Really? ! *&$@!*)^&^
I asked Bestbuy, they said sure, no problem. Circuitcity said, no, you need to run two lines from the dish and a multiplex switch (or something). DirecTV said for 99.00, they'll send someone to install it (not including the receiver, I have to buy that).
I can get a receiver for 50 bucks from Best Buy plus $10.00 for the splitter.
Sorry to both you but, can you answer this question (from your experience)
I want to unplug the coax (from the dish) going to bedroom 1 receiver. Then connect that to the splitter. Then run a coax to each receiver. That is, one coax from the dish going through a splitter, to two receivers.
is that what you did?
Thanks in advance !

This is Turtle.
Yea, but you may not be able to see the tick on the fence post a 100 yards away while watching the regular tv movie. I will not have that and want to see if the tick is laughing or not at the show.

Splitter typically incur some signal loss but if it works, that's good. I never ran into problem using splitter so far. Tony

I'm not too worried about the signal loss. 3 or 4 dB I guess.
What I was worried about is the one signal to two different receivers. The receivers do not have some ... "address"?
I don't know the basics of satellite setups so I was wondering about splitting the signal between two receivers. no worries I guess?
Thanks for all the replies. I mean... $165.00 NOT paid to an installer is $165.00 still in my pocket. After Christmas, it would be nice to hold on to it.
In our previous home, I completely wired the cable TV's so I'm familiar with it. I just wasn't sure about the satellite dish and signals.

Signal loss isn't the issue. You get enough signal, you get all the bits and the picture decodes just fine.
But ... Here's how older DTV systems work.
There are two "bands" of channels on DirecTV systems. Some channels are in one band, some are in the other.
The "band" switching is done at the dish, in the LNB. The receiver puts either 13v or 18v (dc) on the cable, to power the LNB and switch it from one band to another.
The splitter must be able to pass dc so this voltage can be seen by the LNB. Most splitters pass dc, but not all.
The problem is, if you use a splitter, one receiver is tuned to a channel in one band, and the other receiver is tuned to a channel in the other band. One receiver is putting 13v on the cable, one is putting 18v on the cable. This confuses the LNB. The best that will happen is one receiver will work in this situation, the other won't.
If both receivers are tuned to a channel in the same band, it will work fine.
You can buy a cheap switch (~$50) that will take two cables from a dual LNB and feed multiple receivers the desired band signal, using the voltage from the reciever to trigger the switch. Switches exist to switch up to 8 receivers.

umm...
I got this reply from another group. if I have two separate receivers, I should be able to watch different programs on each TV right?
