It takes one incoming cable and splits it into 2,3,4 outputs. Be aware that there is signal loss in any splitter but they work well with strong signal input.
The losses turn up in two forms :
A. The biggest drop in power (per port) is actually just a way the power is divided
among the ports to keep the coaxial cable's impedance (fancy word for inductive/
capacitance resistance) balance, so the signal is not totally destroyed by a
mis-matched connection. To prevent this, the power of the input port is
consecutively divided between all the output ports in the same balanced way,
and there is a reduction in energy/power that is delivered to all ports (normally
divided equally) and the rule of the thumb here is to buy the size of the splitter you
need, and not use that fancy 4-port or 8-port unless absolutely needed.
Normal losses for this are based on the number of ports that you are splitting to.
Number of Theoretical
Output Ports Insertion Loss (dB)
2 3.0
3 4.8
4 6.0
5 7.0
6 7.8
8 9.0
10 10.0
12 10.8
16 12.0
24 13.8
48 16.0
B. Normal losses in imperfect components inside the splitter. Because of the laws of
physics (and quantum physics), there is no perfect conductor, or electrical opponent.
This amounts to about ~0.2 to ~0.5dB for losses in the electrical components inside
the splitter itself.
Another thing to keep in mind is that when you are worried about power, is to carefully
check the Amplifier's gain and noise figures... don't buy an amplifier if you don't need it.
(amplifiers also add noise into the signal and unless you are using a special type, will
mess with your cable modem's upstream connection.
If you do need it, only put the amplifier on ports you DO NEED amplified, and it's worth
the extra money to buy the amplifier with lower noise power. Cheap ones will only add
ghosting and white snow into the picture as extra noise.

∙ 16y agoA cable splitter is used to divide the signal between two or more outputs, and is designed to prevent interference from one device to another.
There is always a `loss` when splitting the signal, usually measured in db's (decibels) and since the incoming signal has a limit of how much signal's available, if you split it too many times, the signal may degrade to the point that it's not usable. Then too, the splitters usually have a frequency range in which they operate, and having one that doesn't cover the entire frequency bandwidth that's needed, that will also degrade the performance.

What is the purpose of a component video splitter?
A component video splitter allows a signal to be transmitted from one device to others. One can connect their cable and with the use of a splitter allow it to be transmitted to a different device.
What is the purpose of using a coaxial splitter?
The purpose of using a coaxial splitter is so that one can connect more than one device to a single coaxial line. For instance connecting two TV's to one coaxial line for cable television.
Where can you get a cable splitter?
Radio Shack.
How does one connect Ethernet cable splitter?
"An ethernet cable splitter allows you to connect two computers to one ethernet connection. Once you have your splitter made, you plug it into both computers just as you would with a normal ethernet cable."
Can I use a cable RCA splitter instead of a Y splitter?
Yes, using a proper splitter is better than a Y cord.
Where can someone buy a component cable splitter?
The best websites to buy a component cable splitter are eBay or Amazon, as they tend to be a little cheaper than elsewhere. It is also possible to buy the cable splitter from a more specialist website such as TV Cables.
Can a PPC and a PCT cable be connected by a splitter?
it can
What is HDMI splitter cable used for?
The purpose of an HDMI splitter cable is to take HDMI signal from a source (such as satellite television service) and split that signal to multiple televisions. Such splitter cables are very handy to have when one owns more than one high definition television and wishes to enjoy high definition programming while saving money.
Can you split cable television to get cable internet?
Yes with a 1000mz splitter for no problems

Will a video cable splitter allow two monitors to work off the same pc?
A video splitter type cable will allow you to view 2 monitors.
Can a bad cable splitter cause sound problems for a TV?
With analog cable and receivers, no. With the use of HD cable receivers, the first sign of a bad splitter is audio dropouts. You should check to make sure that the splitter is rated for a bandwidth of at least 900MHz for digital cable. Changing out the splitter is very easy and cheap, so you should try to replace it and see if the problem goes away.
