Koľko signálu stratí RG58 na 100 m? Slovensko

If you want to transmit a signal, like a TV program or a Wi-Fi connection, something other than an ordinary cable is required for this job. A very common type of cable used for these purposes is known as and similar to coaxial cable, “ This category of cable consists of a central conductor carrying the signal and is encased by insulating layers that protect it from damage. These layers help preserve the strength of the signal as it travels. But there are also instances where the signal might weaken as it travels in the cable. If you get too far away from the source, which gets more flimsy as a signal travels though the air or down a cable, your computer might stop hearing it; this is called "signal loss," and can weaken or even block the signal. 

What RG58 Is and Why It Matters

RG58 is a particular sort of coaxial cable. It is some sort of cable, it usually does a communication role in terms of radios and security camera. Loss in RG58 is crucial as it sends signals over distances and the more loss you have depends on a few different factors. This loss may vary because of a number of factors such as, how long the signal must travel to reach other end and what type of signal you are actually sending over. you can use a spectrum analyzer to see just how much signal loss occurs in kábel rg58. This tool tests the quality of the signal at different places on the cable, that tell you how much a by cable it has lost its signal. 

Signal Strengths Vary By Distance

Another major factor for loss of signal can be attributed to distance in RG58. That cable is a high-resistance medium that resists signal transmission — the longer it is, the weaker the signal becomes as it travels through. For a better explanation, let us take an example: If you use Rg58c u to transmit a TV signal only a few feet, such as from your antenna to the living room, the signal is still reasonably strong. After all, if you broadcast that signal hundreds of miles from a radio tower to your car stereo, the signal loses an incredible amount of strength. Consider this as you create systems that have to convey signals over significant distances. 

Calculating Signal Loss

If you want to find out how much signal loss takes place in RG58, there is a separate formula. Depending on how long the cable is, and what kind of signal you are sending through it, this formula changes to reflect these different properties. While this formula may seem complicated you can find plenty of tools and online calculators that will do the math for you. The only real reason to know as signal loss is in order to find out whether or not you're losing enough of your signal that it's weak by the point it reaches where it demands its lighting. This is similar to making sure your flashlight beam is strong enough before walking into a dark room. 

Signal Loss Over 100 Meters

At this point you may be asking, how much loss will I see after 100m of RG58 cable? Well, that depends. The speed at which the signal travels and fidelity of the cable being used. Typically, you might lose 9 decibels (dB) of signal strength per 100 meters of rg58u cable at a frequency of 100 MHz. Let me put it in other words, when you have a something strong like 10 watts from A and yards later at the B end of that 100m cable you don't get more than about 1 watt. But say you use a better cable — an RG213 or so; this would decrease the signal loss along with the same distance and frequency.
