There are many different things that can go wrong when using a coaxial, or coax, splitter, causing you to lose picture quality, sound definition, or even lose your signal completely. Many people don't understand the science behind coaxial splitters and are baffled when problems continue to manifest themselves over and over. The following article will explain what a coax splitter is and what it does, as well as how to troubleshoot common coax splitter problems when they do occur.
What Exactly Is a Coaxial Splitter?

Coaxial cable lines are produced to provide only one signal to power a singular audiovisual device. This can be an issue in most households where there is more than one device that needs a signal. Coaxial splitters are small connector devices designed with an input line to provide a connection to your existing cable and multiple output lines that tap into your cable's signal and split it into several lines to connect to multiple devices. The number of output lines can be customized to your preference, depending on what the splitter will be used for.
1. Too Much Splitting
Most people fail to realize that the cable signal that runs through their home is not an unlimited source and therefore cannot be split into too many different lines as each split weakens the signal and increases chances of connection failure. If you have more than three TVs hooked up to one cable line and you notice that the signal has been significantly reduced and/or the sound/picture quality available to each TV has been compromised, you may have over-stretched the signal. This problem can be rectified by purchasing an amplified coax splitter which enhances the cable signal while allowing you to distribute to more outputs without risk of failure.
2. Connecting Cable TV to Cable Internet Modem
In order to save cash, many households decide to split their coax cable line to provide both TV and Internet service. Although this is a fundamentally sound idea, the problem with this method is that cable internet requires a strong signal in order to function correctly, and because the signal is being split, there may not be enough power to sustain a good connection, causing poor signal quality or even loss of service. The solution to this problem is to choose a high output, one GHz splitter that is designed to pass a large amount of data. This will allow you to maximize the efficiency of your signal and will usually be enough to reduce any cable/internet connection problems significantly.
3. Improper Cable/Splitter Choice
When choosing a splitter for your home entertainment needs, select the number of output lines you will need for your splitter carefully. Splitters are designed to distribute the signal evenly between each of its connection ports, regardless of how many lines are actually being utilized at any given time. Choose only the amount of output lines you will actually be using in order to avoid weakening your cable signal unnecessarily.
When choosing a cable, the RG6 coaxial cables are the newer type offering a heavier gauge wire with insulation and shielding tuned for high-bandwidth, high-frequency applications such as the Internet, Cable TV, and Satellite TV signals. RG6 cable is your best bet over RG59 built with a much smaller wire which was widely used in the past before satellite and internet, only recommended for low bandwidth and lower frequency applications such as analog video and CCTV installations.
Also, when choosing splitter cables, choose a cable that is long enough to reach each electronic device comfortably, but be aware that the longer the cable line, the further the signal has to travel and the weaker it becomes. If you have a large home or need to stretch your signal across longer distances, it may be necessary to purchase an amplifier splitter to make sure that you are getting the best connection quality possible.
