MOOKEERF CB Coax Cable - RG213 UHF Male to Male 100FT Low Loss RG-213 UHF Cable for Ham Radio/VHF Radio/SWR Meter/Antenna Analyzer
The MOOKEERF CB Coax Cable is a solid choice for anyone needing a long, reliable connection for CB radios, ham radios, or VHF setups. It uses RG213 cable, which is known for its low signal loss, and at 100 feet long, it’s suitable if you need to run cable over a distance without worrying much about losing signal strength. The cable has a bare copper inner conductor and a bare copper braid shielding, which helps keep the signal clear and strong—this setup tends to perform better than some other common cables like KMR400 or RG8. It features UHF PL259 male connectors on both ends, which are standard for many CB and amateur radios, making it widely compatible.

Buying Guide for the Best Coaxial Cable For Cb Radio
Choosing the right coaxial cable for your CB radio is crucial for ensuring clear communication and optimal performance. Coaxial cables are used to connect your CB radio to the antenna, and the quality and specifications of the cable can significantly impact the signal strength and clarity. When selecting a coaxial cable, it's important to consider several key specifications to ensure you get the best fit for your needs.Cable TypeThe type of coaxial cable is important because different types have different levels of signal loss and durability. The most common types for CB radios are RG-58, RG-8X, and RG-8. RG-58 is thinner and more flexible, making it suitable for shorter runs and mobile installations. RG-8X is a bit thicker and offers better performance over longer distances, making it a good all-around choice. RG-8 is the thickest and has the least signal loss, ideal for long runs and base station setups. Choose the type based on the length of the cable run and whether you need flexibility or maximum performance.
Cable LengthThe length of the coaxial cable affects signal loss; the longer the cable, the more signal loss you will experience. For mobile installations, a cable length of 18 feet is common and usually sufficient. For base stations, you might need longer cables, but try to keep the length as short as possible to minimize signal loss. Measure the distance between your CB radio and the antenna, and choose a cable length that provides a bit of extra slack without being excessively long.
ImpedanceImpedance is a measure of the resistance in the cable and is crucial for matching the cable to your CB radio and antenna. The standard impedance for CB radios is 50 ohms. Using a cable with the correct impedance ensures maximum power transfer and minimizes signal loss. Always choose a coaxial cable with a 50-ohm impedance for CB radio applications to ensure compatibility and optimal performance.
ShieldingShielding in a coaxial cable protects the signal from external interference and noise. Cables can have single, double, or even quad shielding. Single shielding is usually sufficient for most mobile installations, while double shielding offers better protection and is recommended for base stations or areas with high interference. Quad shielding provides the highest level of protection but is generally not necessary for most CB radio setups. Consider the environment where you will be using the cable and choose the level of shielding accordingly.
Connector TypeThe connectors on the ends of the coaxial cable are important for ensuring a secure and reliable connection. The most common connector for CB radios is the PL-259, which fits the SO-239 socket on most CB radios and antennas. Make sure the cable you choose has the appropriate connectors for your equipment. If you need to connect to different types of equipment, you may need adapters, but it's best to use cables with the correct connectors to avoid signal loss and connection issues.
DurabilityDurability is important, especially if the cable will be exposed to harsh conditions or frequent movement. Look for cables with a robust outer jacket that can withstand UV rays, moisture, and physical wear. For mobile installations, flexibility is also important, so choose a cable that can bend without breaking. For base stations, a thicker, more durable cable may be preferable. Consider where and how the cable will be used and choose one that offers the right balance of durability and flexibility for your needs.
