Antenna cable - what is it for?
The antenna cable is used to transmit the signal from the satellite dish to the television or DVB-T receiver. Another name for this cable is the coaxial antenna cable. These cables have controlled dimensions, so we can ensure a constant and precise distance between conductors, which is necessary to fulfill the transmission function.
What is the meaning of the antenna cable?
We often forget that to have a great picture, it is not enough to have a smart TV, satellite dish or a top-shelf DVBT antenna. It is equally important to choose the right antenna cable because it is necessary for signal transmission. Deciding on low quality, cheap, and unproven cable, we risk signal loss, interruptions in transmission, and as a consequence - uncomfortable watching TV programs.
Coaxial antenna cable - what to look for when buying?
Based on our company's many years of experience, we can conclude that the choice of coaxial cables is not always obvious. They differ in properties such as thickness, length, core design, braiding density and shielding design. The attenuation value is also a very important element, because every coaxial cable attenuates the signal, with each meter of the antenna cable it becomes weaker. This happens even in cables with so-called top shelf, so check and choose the one with the lowest attenuation. In addition, note the wave impedance, or wave resistance, it should be 75 ohms, because the coaxial antenna cable should have it. Worldwide, two main wave impedance standards for coaxial cables have been adopted: 75 ohms - used almost exclusively for television antennas, VHF applications and FM applications, and 50 ohms - used for amateur CB and car antennas. Returning to signal attenuation, however, an important element is also the thickness of the internal wire, because the coaxial cable having a lower thickness value will maintain optimal signal quality regardless of the length of the cable. In a good quality antenna coaxial cable it will exceed 1 mm, e.g. 1.02 or 1.13.
Choosing a coaxial cable for external use - what should you do?
Antenna cable used for external use should have, above all, thick external insulation, an example is a gel-coated cable, which will effectively increase resistance to adverse weather conditions and damage. In order for our coaxial cable to be even better protected and maintain an optimal signal value, it must be well attached to the ground, maintaining a safe distance from high temperature sources. It should also be remembered that the coaxial cable is not too tight or wrapped in a loop. Compliance with the above recommendations ensures that the antenna cable will not cause problems, and smart TV, DVBT antennas and satellite antennas will work flawlessly.
