What is a RG-58 Coaxial Cable?

RG-58 is a type of 50-ohm coaxial cable commonly used in computer networks and radio communication systems. Its construction consists of a center conductor protected by an insulating layer, a shielding conductor, and an outer sheath.
Known for its flexibility and lightweight, RG-58 is suitable for transmitting radio frequency (RF) signals with little signal loss. It is ideal for local area networks (LANs) and RF systems, where signal quality and ease of installation are crucial for good communication performance.
The Functions of RG-58 Coaxial Cable
RG-58 coaxial cable is used to transmit radio frequency (RF) signals on computer networks and radio communications. Here are some of the functions of RG-58:
- RF signal transmission: RG-58, like other coaxial cables, is designed to transmit high-frequency electrical signals, in this case RF signals.
- Computer networking: This cable is often used in LAN (Local Area Network) networks due to its ability to transmit data stably over short to medium distances.
- Radio Communication: In radio systems, RG-58 is used to connect antennas to radio transmitters or receivers, such as in two-way radio systems.
The Advantages of RG-58 Coaxial Cable

The main advantage of RG-58 coaxial cable is its ability to transmit radio frequency (RF) signals up to a frequency of 1 GHz. Here are some of the advantages of RG-58:
1. High-frequency signal transmission
One of the advantages of RG-58 is its high-frequency signal transmission. This cable can also transmit signals with frequencies up to 1 GHz, making it suitable for a variety of RF applications, such as WLAN, police, fire department, amateur radio, and CB radio.
2. Flexible and lightweight construction
Flexible and lightweight construction is another advantage of RG-58. The construction that makes up this cable makes it easy to install and organize, especially in areas with limited space.
3. Resistant to interference

RG-58 is resistant to interference because it has shielding that is effective in reducing electromagnetic interference, which is important in environments with many electronic devices.
4. Wide applications
RG-58 is used in a variety of applications, from small-scale computer networks to radio transmission antennas, and wireless communications.
5. Affordable price
One of the other advantages of RG-58 is that it is affordable. When compared to other types of coaxial cables RG-58 has a relatively more affordable price, making it an economical choice for many projects.
Those are the definitions, functions, and advantages of an RG-58 coaxial cable that you need to know. Another thing to note is that RG-58 coaxial cable on the market must pass the certification test from the Directorate General of Digital Infrastructure (DJID).
With DJID certification, users can feel calm about using RG-58 coaxial cable technology whose quality and security are guaranteed. For manufacturers or importers of this technology, obtaining certification from DJID is a mandatory step before the device can be officially marketed in Indonesia.
To simplify the certification process, you can use Type Approval Certification Services for ICT Products are available to assist with this process as a reliable solution.
