Coaxial cable used to connect radio modem and antenna
Coaxial cable is used to connect a radio modem to its antenna. It helps maintain signal integrity and reduce electromagnetic interference. It consists of a central conductor surrounded by an insulating layer and a conductive shield.
The SYV-3, SYV-5, SYV-7, and SYV-9 are different specifications of coaxial cables, each with its own characteristics and applications. Here are their similarities and differences:
SYV-3: This is the thinnest among the four, with a smaller diameter and less shielding. It is suitable for short-distance signal transmission where flexibility is required.
SYV-5: Slightly thicker than SYV-3, it offers better shielding and signal integrity over slightly longer distances.
SYV-7: With a larger diameter and more robust construction, it provides better signal transmission over longer distances and is more resistant to signal degradation.
SYV-9: This is the thickest and provides the best signal integrity and resistance to interference over long distances. It is often used in applications requiring high reliability and minimal signal loss.
The thinner the coaxial cable, the greater the insertion loss, and the distance between the radio and antenna needs to be closer. These differences make each specification suitable for various applications depending on the required transmission distance and the level of signal integrity needed.
