How to Split a DirecTV or Dish Network Satellite Signal
There’s no need to call a technician if you want a DirecTV or Dish Network cable splitted to accommodate two or more television sets.
First, let’s review how a satellite TV system works.
A satellite TV signal is collected by the dish. Through the LNB, this signal travels down the cable as a raw, encrypted MPEG2 into the satellite TV receiver where it will be decrypted and processed into a signal viewable by a television.
Before the signal passes through the satellite TV receiver (also known as a satellite dish set up box), the signal in its raw form is around 11 to 21 Ghz MPEG-2 and is encrypted, so you’ll need a suitable receiver that can process this signal, or has the necessary “keys” to decrypt or unlock it.
After it passes the receiver, this signal becomes any regular television signal. Using any conventional cable splitter, you can split this signal indefinitely or up to the limit of most splitters, which is four cables.
The only caveat is that all television sets added into this loop will show the same satellite TV programming controlled by the only satellite TV receiver.
If you want every television set to operate independently of the other, you will need an additional satellite TV receiver for every additional television set. To do this, simply split the signal using a multi-switch right after it passes the satellite dish and before it passes a receiver. A multi-switch will allow up to four receivers and television sets that will operate independently of each other.
