RG Coaxial Cables

 What is an RG213 cable?

There are multiple types of coaxial cable, each with a different diameter and impedance. Coaxial cable is usually not affected by external interference, and is capable of high data transmission speeds over long distances.

In turn, the initials "RG" correspond to the abbreviation of "Radio Guide" (Radio Guide), a term that dates back to the time of World War II, when the US military made extensive use of coaxial cable and developed a set of standards to specify the different grades of coaxial cable and their applications.

Subsequently, the cable types listed on the RG list were no longer sufficient. The cables were reorganized and numbered by the MIL type designation (MIL-C-17 = US Military Requirement).

Specifically, the RG213 cable is a 10mm thick high frequency cable useful for most RF (Radio Frequency) applications.

RG213 Cable Specifications

RG213 cable has several important technical specifications that make it suitable for a wide variety of applications. Some of these specifications include:

  • Characteristic impedance: 50 ohms
  • Spread Speed: 66%
  • Return Loss: 20 dB at 1 GHz
  • Insertion loss: 0.35 dB/m at 1 GHz
  • Temperature range: -40 °C to 85 °C

 RG cable types

In addition to the RG213 cable, which is undoubtedly one of the most common and most used on the market, we have many other options within this family of coaxial cables.

Available depending on the coaxial cable model, with different options for both sheath (PVC, PE, LSZH-FR) and presentation of the cables themselves (in more manageable rolls of 100 meters, or in coils of greater footage).

RG213 Cable Applications

RG213 cable is used in a wide variety of applications, including:

  • Radio communication systems: RG213 cable is commonly used to connect antennas and two-way radios.
  • Cable and satellite television systems: RG213 cable is used to carry high-quality video and audio signals from the satellite dish to the receiver.
  • Test and Measurement Equipment: RG213 cable is used in high-precision measurement instruments such as oscilloscopes and spectrum analyzers.
  • Process control systems: RG213 cable is used in industrial process control systems to transmit measurement and control signals.

 Advantages and benefits

RG213 cable has several important advantages that make it popular in a wide variety of applications. Some of these advantages include:

  • Low Signal Loss: Due to its low insertion loss and high return loss, RG213 cable is capable of transmitting high-quality signals over long distances.
  • Weather Resistance: RG213 cable is designed to withstand harsh environmental conditions such as rain, wind, and direct sunlight.
  • Durability: RG213 cable is designed to withstand heavy-use conditions and last for many years without the need for maintenance.
  • Great flexibility.
  • Manufactured under MIL C17 regulations.
