There are various types of splitters available in the market. You can get 2-way, 4-way, 8-way and many other splitters. It is always advised to get the smallest splitter since when you think of making use of the bigger splitter for the future of the system. What you are actually doing is making the current system even less reliable. Generally, it is advised to avoid taking splitters apart from 2, 4 and 8. The splitters which are odd numbered have the same loss when compared to their next even numbered ones. Hence this way, you would be only losing out on the port. For example, a 3-way splitter is considered to be as bad as a 4-way one. The splitters which are mostly bigger than 8-way would tend to make you lose out on 90percent of the original port. Hence even that is not considered to be a good deal.
Each of the splitter is made of various defined bandwidth. The Coaxial cable is known to be carrying all of the things which it does due to the different signals that tend to take up various parts of the cable. You can compare it very much to the radio FM. Varied things make use of different frequencies hence whenever it is possible, they would be sharing the same wire. When two of the different services are making use of similar frequencies, they would not be able to use on the same cable or the same splitter. Let us have a look at the different bandwidth required by different services:
These are mostly considered to be the simplest of the things to which you can connect a splitter. In such cases you can look out for splitters which would be able to handle around 50 to 800MHz. You would be able to find splitters that also work with even larger range.
The cellular boosters make use of the same frequencies as the cellular radios. Their frequencies are considered to be higher than the broadcast television to avoid any kind of interference among the two. The splitter would need to work up the frequencies in a range of 600 to 1900MHz in case of cell boosters.
Talking about the cable and satellite TV, there is a lot of thing packed out there hence they would need a lot of bandwidth. The cable TV tends to make use of similar bandwidth as the broadcast TV but just adding a bit more. The higher frequencies allow you to have more number of channels than the broadcast TV whereas the smaller frequencies are used for the internet. You can choose a splitter in the range of 5 to 1000MHz.
DISH or older Satellite TV:
You can call the satellite TV as the complex ones since they tend to carry thousands of channels from various sources. It is designed to work along with the cable internet. The splitter in their case should be able frequencies ranging between 5 to 2150MHz.
In case if you are new for splitter then go in for the splitter which would match the bandwidth mentioned above. Rest all would fall in place.
