How Directional Couplers Make Life Easier

By Ericka Marsh


Most of the television sets and your devices like the radio and your computer rely on radio frequency for it to gather signal and for it to function. This is what most cable companies use. When the signal is weak, you can expect that you cannot have good reception when you are watching the television. There are times when the issue is not in weak signals, it is because it is not distributed properly.

There are devices that you can use to improve the strength of the frequency. You can make use of a power divider. But if you are aiming to distribute to more devices, you will benefit more from directional couplers. Most of the time, it is hard to distribute frequency among different devices especially if you are using one source. Through the couplers, this can easily be accomplished.

You might be confused regarding the function of the coupler and the divider. Most of the time, their function are just the same. However, there are different situations when you can use these. When you use dividers, it would be for lesser devices since there are just two ports. Couplers are utilized for more appliances since it has more ports.

The application of these things vary on what you are going to use them for. Usually these things are used to make sure that the power and the strength of the signal is properly distributed to each of the devices that needs it. This usually works for homes that have several devices that needs radio frequency especially television sets.

This can also be used for monitoring. If you are trying to figure out where the problem exactly lies, you can use these devices to measure the frequency passing through each of the ports. If one area is lacking or there is just too much signal, you can easily see it. The best thing is the part that you do not have to tap into the main power source to remove it.

There is hybrid types of couplers. When you have more devices that you need the frequency to be distributed on, then it would be good to make use of this one. This will help you achieve a clearer resolution even if you are using the coupler as long as it is hybrid.

Aside from splitting the signal so that it can be used further, you can also use it to combine power. This is when you want to improve the signal strength. Through combining the power, you can effectively increase the resolution of the display. This is usually what the coupler is being used as well. The collective power will make frequencies collected in one port.

Too much frequency and power would be bad as well. The supply should just be right. It would not only mess up the reception. It will increase the reflection and this is the reason why you can see more images on the screen. To prevent this, some of the signals have to be isolated in one of the paths. Since dividers only have to paths, they are not suitable for this job.

There are many people who would like to install these things on their own. This is perfectly understandable since it is your home and your devices. But you will be needing the basic knowledge for it. You will also make use of tools.
