Coaxial cables, often shortened to “coax,” are a specialized type of electrical cable with a unique design that provides excellent signal transmission and protection against interference. Here’s a breakdown of their structure and function:
At the heart of a coaxial cable lies:
- Inner Conductor: A solid copper or copper-clad steel wire that carries the electrical signal.
- Dielectric Insulator: A non-conductive plastic layer that surrounds the inner conductor, maintaining a precise distance between the inner conductor and the shield. This spacing is critical for proper signal transmission.
- Conductive Shield: Usually made of braided copper or aluminum foil, this layer shields the inner conductor from electromagnetic interference (EMI), which can distort the signal.
- Outer Jacket: A flexible plastic sheath that provides protection and insulation for the entire cable.

- Monster Essentials RG-6 Coax Cable
- GearIT Coaxial Cable
- Quad Shield Solid Copper 3GHZ RG-6 Coaxial Cable
How Coax cables work
The “coaxial” design (where the inner conductor and outer shield share a common axis) is key to the cable’s function. The signal travels through the inner conductor, while the shielding blocks external interference. This allows coax cables to transmit high-frequency signals over long distances with minimal distortion and signal loss.
Applications of Coax cables
Coaxial cables are widely used in various industries and households due to their reliability and signal-carrying abilities:
- Cable Television: Coax cables are the standard for delivering television signals from a provider to homes and businesses.
- Internet Connectivity: Many cable internet services rely on coaxial cables to deliver high-speed broadband data.
- Radio Communications: Antennas for radios and similar devices often use coaxial cable for efficient signal transmission and reception.
- Computer Networking: Older computer networks sometimes use coaxial cables, although they’ve largely been replaced by twisted-pair Ethernet cables.
- Test and Measurement Equipment: Coaxial cables are used in laboratories and testing environments due to their ability to accurately carry sensitive signals.
Types of Coaxial cables and connectors
Different types of coaxial cables exist, each optimized for specific use cases. They are classified by impedance (typically 50 ohms or 75 ohms) and RG (Radio Guide) ratings, indicating characteristics like diameter and shielding.
- Impedance: Typically 50 ohms (for radio communications) or 75 ohms (for video transmissions).
- Thickness: Measured using the Radio Guide (RG) system. Thinner cables (higher RG numbers) generally have greater signal loss.
- Connectors: Common connector types include BNC (radio/test equipment), F-type (cable/satellite TV), and RCA (consumer audio/video).
Advantages of using Coaxial cables
Coaxial cables, also known as coax, are versatile and reliable for transmitting data, video, and audio signals across various applications. Their unique design and properties offer several distinct advantages:
- High Bandwidth: Coaxial cables support high bandwidths, meaning they can carry a large amount of data in a short period. This makes them ideal for applications like high-speed internet, cable TV, and other demanding data transmission tasks.
- Signal Integrity and Interference Resistance: The shielded design of coaxial cables, with an inner conductor surrounded by insulation and a conductive outer shield, minimizes external electromagnetic interference (EMI). This ensures that signals remain strong and clear, even in environments with other electronic devices.
- Durability: Coaxial cables are constructed to be durable and withstand some level of physical stress. This makes them suitable for indoor and outdoor installations where they may be exposed to the elements or potential damage.
- Scalability: Coaxial cable networks can be easily expanded to accommodate additional devices or extend their reach. This flexibility makes them adaptable to changing needs.
- Ease of Installation: Working with coaxial cables is relatively straightforward, requiring simple tools and techniques. This contributes to lower installation costs and faster deployment times.
- Cost-effectiveness: Compared to alternatives like fiber optic cables, coaxial cables offer a more affordable solution for many applications, especially those requiring shorter distances.
Additional considerations
While the standard transfer capacity of traditional coax cables was in the 10Mb range, advancements in coaxial technology have led to significantly higher bandwidth capabilities for modern cables.
Coaxial cables excel at transmitting signals within the conductor, minimizing signal loss and power leakage. This characteristic also allows for their installation near metallic objects without significant interference concerns.
