RG58 is a type of coaxial cable that's been around since the 1950s. It's a 50-ohm cable, which means it has a characteristic impedance of 50 ohms, and it consists of a center conductor, an insulating layer, a braided shield, and an outer jacket. It's also known as RG-58/U, with the U standing for "universal." This designation means that RG58 is suitable for a wide range of applications.
2. RG58 Specifications
When it comes to specifications, RG58 has a few key features that make it stand out. Here are some of the essential specifications you should be aware of:
As mentioned earlier, RG58 has a characteristic impedance of 50 ohms. This specification is critical because it ensures that the cable is matched to the impedance of the system it's being used in. A mismatched impedance can lead to signal loss and reflections, which can affect the performance of the system.
RG58 has a frequency range of up to 1 GHz. This specification is important because it determines the maximum frequency that can pass through the cable without significant signal loss. For most applications, RG58's frequency range is more than enough.
Attenuation is the loss of signal strength as it travels through the cable. RG58 has a typical attenuation of 11.5 dB/100 ft at 1 GHz. This specification is crucial because it affects the maximum length of the cable that can be used in a particular application.
Capacitance is the ability of the cable to store electrical charge. RG58 has a capacitance of approximately 30 pF/ft. This specification can affect the performance of the cable in high-frequency applications.
RG58 is a versatile coaxial cable that can be used in many different applications. Here are some of the most common uses of RG58:
RG58 is commonly used in radio communication systems, including two-way radios, CB radios, and amateur radio. It's an excellent choice for these applications because of its high-quality signal transmission and attenuation characteristics.
RG58 can also be used for Ethernet applications, particularly in older systems. It's not as commonly used for Ethernet as it once was, but it's still a viable option for some applications.
RG58 is often used for CCTV (closed-circuit television) systems because of its ability to transmit video signals over long distances without significant signal loss.
RG58 is frequently used for test and measurement applications because of its high-quality signal transmission and impedance matching characteristics.
