How far can coaxial cable lose signal?

When we plop down to watch our favorite TV shows or jump onto the internet — and like me, you feel as if these daily human-rights have existed since the dawn of civilization — funny to reflect back on all the technology that goes into things. Coaxial Cable – Coaxial cable is a hugely important part of both our entertainment and connection to the internet. 

Coaxial cable is different kind of wire. It consists of a center wire encased in shield This layout is so useful because it maintains the sign solid and clear. How far coaxial cable signal maintain a clear image? Well, let us take a look next. 

Why Coaxial Cables Drop Signal?  

All cables are subject to signal degradation, and coaxial cable is no exception. A long cable with send a weaker signal, which means it may not work as efficiently. That means coaxial cable can also lose echo of a signal, which could lead to poor-quality TV shows or slow internet. 

There are multiple factors which determine how much the signal will lose. Thing is that various of types exist depending on the length, type of signal it transports and how good the quality of cable is. For example, it is intriguing to see that higher frequency signals have much less range than lower frequency ones. When you are having the signal of high frequency, it has higher chance to become less in magnitude over longer distance. 

What is coaxial cable signal length?  

A very important specification with coaxial cable is its distance. A cable of greater length could reduce the signal. Coaxial cable can generally send signals over a distance of 500 meters (1,640 feet) while still maintaining the strength of the signal. But, of course, this distance can vary depending on the quality of the cable as well as some other things like what type of signal is being driven over it. 

Higher quality coaxial cable can maintain its signal strength longer over lengths. This sooner or later weakens the signal, however if the cable is not excellent that can occur quicker. Thus we need to take care of the quality of coaxial cable assembly we are using. 

What signal loss threshold is? 

Now, every cable has its own threshold on how much signal it is allowed to loss — this is called the “signal loss threshold.” Coaxial cable has a limit and can only lose so much signal before it becomes too weak to deliver a clear signal. 

With coaxial cable, the signal loss threshold for a 100 meter (or 328 foot) long length of cable is usually around 20dB (decibels). It is up to 20dB: If the signal loss is more than 20dB means that not very well receive a bad antenna signal, and then our TV will be a blurred image or at other times the internet speed may be low for some site. 

The Distance Factor on Signal Quality

We know that if we extend the distance, signal quality of the coaxial cable work is affected, but in what limit? To illustrate, let me share a real life example. Let say you have a 50 meters long coaxial cable (164 feet) On the other end of the cable run, we start out with a relatively strong signal at 100% strength. However, the signal travels down along the cable and by the time it reaches the end may have lost 50%, or even more. This big loss was enough to make our TELEVISION images go blurry or pixelated during live programs and that is extremely discouraging. 

Maintain a Strong Signal Over Long Distance

OK, then How to Keep the Signal when using long coaxial cables? This is where boosters or amplifiers come into play. The most basic definition of a broadband signal booster is that it is an amplifier that can be placed at regularly spaced intervals along the cable run to help boost the signal. This allows the signal to travel a greater distance without losing too much strength. 

The next option is to use a good coaxial wire instead. The higher the quality of cable, the lesser its chances of signal strength getting lost. Better cables are usually built to survive at longer distance runs while maintaining good signal quality. 

Proper installation and regular upkeep can also maintain the signal at high strength levels. Better protection is provided by shielding with proper grounding of the coaxial cable. Whenever any reduction or injury has occurred to the cable, it must be immediately corrected to keep the signal clear. 

Well, to summarize in a word, Coaxial cable: entertainment and the making of utilized for our broadband internet services. But if you are 30 to 50 feet away it loses signal. You can learn the types of gains in different frequencies, how far you can let a signal fall off before it fits out, and other details that will allow you to make your SOTA signal as strong as possible. These are the solutions to all these problems and we can continue watching our favorite TV shows and getting connected to the internet without frame problems or at poor-quality.
