Understanding the intricacies of this essential piece of technology is crucial for engineers, technicians, and enthusiasts alike. In this comprehensive guide, we delve into the inner workings of RG58 coaxial cable, exploring its construction, features, applications, advantages, and future prospects. Join us on a journey to uncover the wonders of RG58 and its enduring impact on the world of communication.

What is RG58 coaxial cable?

RG58 coaxial cable is a type of electrical cable known for its coaxial structure, consisting of a central conductor surrounded by a dielectric insulator, which in turn is encased in a conductive shield and an outer insulating jacket. This construction allows for the transmission of electrical signals with minimal interference and signal loss, making RG58 coaxial cable a popular choice for various applications.

One of the key features of RG58 coaxial cable is its impedance, typically around 50 ohms, which makes it suitable for use in telecommunications, data transmission, and networking systems. Its ability to maintain signal integrity over long distances, coupled with its relatively low attenuation characteristics, makes it an ideal choice for transmitting high-frequency signals efficiently.

The importance of RG58 coaxial cable lies in its reliability and versatility across a wide range of industries. In telecommunications, RG58 is commonly used for connecting antennas to radios, enabling efficient transmission of radio frequency signals. In data transmission and networking, it serves as a vital component in Ethernet and other networking systems, ensuring stable and high-speed data transfer.

Furthermore, RG58 coaxial cable finds extensive applications in CCTV systems for transmitting video signals with minimal interference, as well as in amateur radio setups where its flexibility and ease of installation are highly valued.

Basic structure of RG58 coaxial cable

Inner Conductor:

The inner conductor is typically made of solid or stranded copper wire and serves as the core through which electrical signals are transmitted. It is surrounded by a dielectric insulator to maintain signal integrity.

Dielectric Insulator:

Surrounding the inner conductor is a dielectric insulator, which is usually made of materials like polyethylene or foam polyethylene. The dielectric insulator provides insulation between the inner conductor and the outer shielding, preventing signal loss and interference.


The dielectric insulator is encased in a conductive shielding layer, which can be made of braided copper or aluminum foil. The shielding layer acts as a barrier, protecting the inner conductor from external electromagnetic interference and preventing signal leakage.

Outer Jacket:

The entire structure is then covered with an outer jacket, typically made of PVC (Polyvinyl Chloride) or other durable materials. The outer jacket provides mechanical protection and insulation, safeguarding the cable from environmental factors such as moisture, abrasion, and temperature variations.
