Understanding RG numbers for the central cables is necessary to choose the appropriate cable for your needs. Axial cables are commonly used in various applications, including television, internet and radio frequency. RG numbers are a major identifier for these cables. Below, we will discuss the RG numbers in detail, which helps you make enlightened decisions when choosing the axial cables.
The meaning behind the RG numbers
RG symbolizes “Radio Guide”, a term that originated from the military specifications of the central cables during World War II. Today, RG numbers no longer follow these original specifications but remain a common system. Each RG number is associated with specific cable dimensions, such as the basic conductor diameter and shielding thickness.
The RG number also provides an insight into the cable resistance, usually measured by ohm (ω). Displacement indicates how cable is resistant to electrical signals, which is very important to sign quality. For example, RG-6 cables are usually resistant 75ω, making them ideal for TV and satellite signals.
Isolation and shield
The RG number of the axial cable also reflects the type and level of insulation and shield it offers. Insulation is located around the basic conductor and prevents the signal loss, while the cable is protected from the overlapping of the external signal. Various RG numbers indicate different levels of effectiveness in these areas, which can greatly affect performance.
For example, the RG-6 cables are characterized by the formation of strong protected layers to reduce overlap, making them a preferred option for high-frequency applications such as HDTV and wide-range internet. Meanwhile, RG-59 cables are suitable for low-distance uses such as the basic video connections in old systems. The choice of the wrong RG cable can deteriorate sign quality, especially in high -order applications.
Various RG cable applications
Various RG numbers determine the perfect cable applications. Thanks to high-quality shielding and effective shield, RG-6 cables are used frequently for digital cable TV, satellite satellite and Internet connections. On the other hand, RG-59 cables are generally found in analog video applications and low-frequency domain systems. Its diameter and the lower shield make less convenient for modern and high -frequency requirements.
It should also be noted that the latest variables of RG cables often feature advanced insulation materials and external jackets, which improve durability and weather resistance. For this reason, RG numbers can also indicate whether the cable is suitable for internal, external, or inside the wall.
Choose the right cable with the RG numbers in mind
When choosing a pivotal cable, carefully think about what RG number refers to in terms of disabilities, shield and intended application. Matching these features with your specific requirements is very important to ensure optimal performance. The use of the wrong RG cable, such as the cable that has an insufficient shield, can lead to poor signal quality and frequent interruption in the service.
Understanding what RG numbers mean for axial cables also ensures compatibility with your equipment. Certain devices work better with specific disabilities levels, so the use of the appropriate RG cable avoids possible system problems and increases efficiency.
