Cable Type
The co-phase design is perfect for CB antennas, requiring only a small hole to pass through.
Connector Type
The screw-on ends make installation through tight spaces incredibly easy.
Durability
This cable provides a solid connection, enhancing overall performance.

The Wilson 18ft Co-Phase Cable with FME Antenna Mini 8 Dual is a solid choice for CB radio enthusiasts. One of its standout features is the FME end, which allows the radio-side PL-259 connector to unscrew. This makes it particularly convenient to install the cable through tight spaces without needing to cut or solder, simplifying the setup process.

The cable itself is a low loss CB antenna mini-8 RG-8X coaxial, known for providing good performance with minimal signal loss, thanks to its tinned copper stranded center conductor and high shielding percentage. This ensures reliable communication with reduced interference. Additionally, the cable is designed with weatherproof vinyl boots to protect its connections, enhancing durability and making it suitable for both indoor and outdoor use.

However, at 18 feet, the length of this cable might be more than what some users need, potentially causing excess cable management challenges. This product is well-built for CB radio installations, offering ease of installation and reliable performance, though its length might be overkill for certain setups.

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.
