RG213 is a type of coaxial cable that is commonly used for various applications, including radio frequency (RF) and telecommunications. It is known for its durability and signal-carrying capabilities. Here are some key characteristics of RG213 coaxial cable:

1. Impedance: RG213 cables typically have an impedance of 50 ohms. This is a common impedance for RF applications, such as connecting antennas to transceivers and other communication equipment.
2. Signal Loss: RG213 cables have relatively low signal loss, making them suitable for applications that require minimal signal degradation over long distances.
3. Diameter: RG213 cables are relatively thick and have a larger diameter compared to many other coaxial cables. This thickness contributes to their durability and ability to handle higher power levels.
4. Shielding: RG213 cables typically have a braided shield that provides excellent protection against interference and signal leakage.
5. Connectors: RG213 cables are often terminated with connectors compatible with the specific devices or equipment being used. Common connectors for RG213 cables include N-type connectors and PL-259 connectors.
6. Applications: RG213 coaxial cables are commonly used in amateur radio (ham radio) setups, cellular signal boosters, and other RF applications where a robust and low-loss cable is needed.

It's important to note that RG213 cables come in various lengths, so you can choose the length that suits your specific installation requirements. When selecting a coaxial cable, it's essential to consider factors such as impedance, signal loss, shielding, and the type of connectors needed to ensure it meets the needs of your application.
