Coaxial cable is undoubtedly one of the most important types of electrical cables. It has an internal geometric axis. First of all, it is distinguished by the fact that its dimensions are fully controlled. This allows you to obtain a precise distance between individual conductors. It is worth learning more about it and choosing the highest quality models.

Where will a coaxial cable be useful?
Coaxial cable is also referred to as telecommunications cable . It is used to transmit signals that are variable and have low power. It has a wide range of applications in various types of installations, from network, through cable, to antenna and transmission. Coaxial cables and wires have a characteristic structure. They have an electric cable that generates minimal resistance to the electrical impulse. It also has internal insulation, e.g. from polyethylene. Thanks to this construction, it will actually work well in installations that do not require fast transmission. Moreover, it can be used to get rid of distortions in the viewed image. It can be used in CCTV or computer networks.
How to ground a coaxial cable?
Grounding a coaxial cable is not complicated at all. First of all, the cable shield should be grounded by connecting it to the lightning protection installation. This provides protection against atmospheric surges. You also need to remove the external insulation. Then wrap the braid around the cable ground. It is best to use a metal tape that is resistant to mechanical damage. You can use an alternative solution that will not damage the cover. In this case, the mast and the places where the cables are connected should be grounded. The mast and cable ties are connected together. You can also attach them to a grounded sheet. At the same time, we would like to remind you that in such a case, each device must be connected with separate cables equipped with a grounding strip.
How to check the signal in a coaxial cable?
Coaxial cables are quite simple to install. Remember not to bend the cable too much. Additionally, cables should not be too close. It is best that it is not smaller than 25 cm. After connection, check the signal in the coaxial cable. First of all, you can use a universal meter. This way you can be sure that the signal is transmitted properly at both ends.
All you need to do is set the meter's sensitivity knob to the highest value and then position the antenna so that the meter pointer deflects and the sound intensity is higher. The signal strength level must be clear. This applies to both terrestrial and satellite television. The power dissipated in the resistance should not be lower than 75 Ohm. Moreover, you can also check the antenna signal. All you need to do is turn on the TV and use the channel search function.
