Do HDMI Couplers Degrade the Signal?

In our daily usage, we all came across the HDMI cable. And sometimes, we may need to prolong the HDMI cable. There is a huge possibility to learn about HDMI couplers when we are in the process of prolonging HDMI cables. It is also known as HDMI barrels. HDMI couplers are the mainstream way to prolong your cables. You connect them with a coupler and boom! You are ready to go! But the question arrives is this the best way out there?

When we use the HDMI coupler, there is a high chance that it will degrade the signal. And as with the period and gradual increase of usage, the cables may be wag around and even cleave when the cables are stretched out. Usage of the HDMI Balun kit can be a superior accomplishment for this puzzle. It uses Ethernet to dispatch signals making an end within the devices in exchange for an HDMI cable.

Numerous of authorization are there to unravel this. And each of the authorizations has its distinct amenities and inconvenience assimilating to an HDMI coupler. And most importantly, we should know that the HDMI coupler should be treated as a lost puppy despite all of these.

What is an HDMI Coupler or Barrel?

There are many parts in our modern technology which soothe our user experience, and under different circumstances, we may have to come across different products. And an HDMI coupler is that kind of a tiny product that consolidates two different HDMI signals via two turned upside-down female jacks. Because most of the cables we have are male to male, having female jacks into the devices has perks. Because if anything hit or dropped, the female jacks protect the male cables. As most of the HDMI cables available in the market are male-to-male.

As many as pins are there in the HDMI cables connects through an HDMI coupler that concludes the signal between two HDMI cables. And what the HDMI coupler does is connects the female jacks of the male HDMI cables. Simply we can say that the coupler built a bridge between two HDMI cables.

In our day-to-day life, it is known ideal to have a single, prolonged cable. But the theory says that a bridge between the male and female cable will be the same criteria as a single continued cable.

Why HDMI Coupler is Not the Best Option

It is very well known that we face various problems in our technological world like radio interference and instrumental malfunctions. That’s why the HDMI cables are shielded with different insulating materials and alloys to minimize radio interference. But the protection is compromised when the shield tore down or got damaged.

We have known many couplers brands, but we will talk about this Amazon Basics model as an example. The body of this cable is very plastic KY, unlike how a cable should be. Lack of proper shielding makes it more amenable and inclined to network interference.

Analog signals have their advantages because they may blend with the radio interferences, unlike the digital signals, which are more submissive to the disputable inconvenience. So here is the problem that arises with the coupler.

Moreover, when we have a long cable with tiny pieces attached, it can cause unexpected catastrophe as it is strolling around the floor. And the more we attached tiny pieces to create a long one, the more unstable the jacks. If someone swings over the cable or something are expected to happen, the cable will get damaged, and the pins can be misaligned. 

How to Properly Extend HDMI Cables

How to Properly Extend HDMI Cables

Generally, we would want a hassle-free solution where the system would allow us to get around any cables and have a convenient system. And for that, the solution does exist like the  Diamond Multimedia HDMI Extender Kit (on Amazon). A wireless system uses the wifi signal to send contents between the devices using their HDMI jacks and wireless transmitters.

But the world of media is changing every moment. It is being perfected every moment and enhancing and facing evolution. And it has outpaced the capacity of the WIFI signal because the wifi signal is limited with bandwidth. We can not take full advantage of UHD, 4K, 8K, surround sound, and many other using a wireless kit because it can be very expensive at the same time, there will be a question of efficiency. And a sweet reminder is that if something makes you interested, we have done our homework about that too. We have set a depth review about that too. But for this efficiency thing, you should also consider the balun kit.

Now we have to know about the HDMI balun kit, which has two components. One that converts the HDMI signal into something that cat cable can send through the Ethernet. And the other one converts the signal into an HDMI signal. And these units like  J-Tech Digital HDMI Extender (on Amazon) aren’t nearly as expensive as equivalent wireless HDMI options.

Why Cat Cables are Better for Long Runs:

Cat Cables

When it comes to longer cable runs, the cat cables will have the winning position against HDMI cables because the cat cables have their specific advantages. The first thing is to be noted about cat cable is that it is lightweight and unshielded, and it has only four pins in it, which creates great stability in our daily usage of prolonging cables than our standard HDMI cables.

Moreover, if we want to talk about cable management, the cat cables are way easier to use and clear traffic. And when it comes to cable mounting, we can rely on the cheapest options that cable management can have. We can choose the mounting cable clips. It can be attached to the wall or ceiling or an extra pair of tools where the cables hide underneath them, making it very convenient. 

It is mentioned that cable clips leave the cat cables exposed, making them highly vulnerable to radio interference. And if the cat cables look eyesore, then we can get cable raceways to hide the cables. It can be defined as the hideaway for the cables mounted in the wall, and we can give it a disguise by painting it the same color. We can give it some alternative to show it more elegantly. And even we can route it inside the wall to hide it from our site completely.

One of many other reasons the cat cables are more reliable than the HDMI cable in the long run. And the cat cable prices are more reasonable than the traditional HDMI cables. Most of the HDMI cable brands don’t make the cables more than 25 feet, and if we don’t want to compromise with the quality of the signal, then the cables more than 12 feet can price a good amount of money.

Conclusion:

Though we have seen and discussed the shortcomings of the HDMI cable, the HDMI cable can come in handy in many ways, like compacting our house systems. But if we have a bigger project and have to show something outside a room, the HDMI will not be suitable. Using Ethernet and other wireless options, we can solve the problem, and most importantly, these are more superior options than an HDMI cable.
