# RG213 Product Series: A Comprehensive Guide to High - Performance Coaxial Cables
## Introduction
The RG213 product series stands as a cornerstone in the realm of coaxial cables, renowned for its exceptional electrical and mechanical properties. These cables have been a staple in various industries for decades, offering reliable signal transmission in a wide range of applications. Whether it's in telecommunications, radio frequency (RF) systems, or military and aerospace applications, the RG213 series has proven its mettle time and time again.
## Physical Characteristics
### Construction
The RG213 cables are constructed with a meticulous design to ensure optimal performance. At the core, they feature a solid or stranded copper conductor. The solid copper conductor provides excellent conductivity and low resistance, which is crucial for minimizing signal loss during transmission. Stranded conductors, on the other hand, offer greater flexibility, making them suitable for applications where the cable needs to be bent or moved frequently.
Surrounding the conductor is a dielectric layer, typically made of polyethylene (PE). Polyethylene has excellent electrical insulation properties, which help to maintain the integrity of the signal by preventing interference and leakage. It also has a low dielectric constant, which allows for high - frequency signal transmission with minimal attenuation.
Over the dielectric layer, there is a shielding layer. The RG213 series commonly uses a double - shielded design, consisting of an inner aluminum foil shield and an outer braided copper shield. The aluminum foil shield provides excellent coverage and helps to block out electromagnetic interference (EMI) and radio frequency interference (RFI). The braided copper shield adds an extra layer of protection, enhancing the cable's ability to withstand external interference and also providing mechanical strength.
Finally, the cable is encased in an outer jacket, usually made of polyvinyl chloride (PVC) or polyethylene. The outer jacket protects the internal components of the cable from physical damage, moisture, and environmental factors such as UV radiation.
### Dimensions
The RG213 cables have a standard outer diameter of approximately 0.405 inches (10.3 mm). This relatively large diameter contributes to the cable's durability and its ability to handle high - power signals. The inner conductor diameter is typically around 0.085 inches (2.16 mm), which is optimized for efficient signal transmission at a wide range of frequencies.
## Electrical Performance
### Impedance
One of the key electrical characteristics of the RG213 series is its impedance. These cables are designed to have a characteristic impedance of 50 ohms, which is a standard impedance value in many RF and microwave systems. This impedance matching is crucial for minimizing signal reflections and ensuring maximum power transfer between the source and the load.
### Attenuation
Attenuation refers to the loss of signal strength as it travels through the cable. The RG213 series offers relatively low attenuation, especially at lower frequencies. For example, at 100 MHz, the attenuation of an RG213 cable is typically around 0.15 dB per 100 feet. As the frequency increases, the attenuation also increases, but the cable still maintains acceptable performance up to several gigahertz. This low attenuation makes the RG213 cables suitable for long - distance signal transmission without significant loss of signal quality.
### Power Handling Capacity
RG213 cables are known for their high power handling capacity. They can handle relatively high - power RF signals without overheating or suffering from excessive signal distortion. This makes them ideal for applications such as high - power radio transmitters, where the cable needs to carry large amounts of power without degrading the signal.
## Applications
### Telecommunications
In the telecommunications industry, the RG213 series is used for connecting antennas to base stations, repeaters, and other communication equipment. The low attenuation and high
