The RG214 Cable is a high-performance 50 Ohm coaxial cable designed for reliable RF and microwave signal transmission in applications where shielding, durability, and signal integrity are important. Its double-shielded construction provides improved protection against electromagnetic interference (EMI) and radio-frequency interference (RFI), making it suitable for communication systems, test equipment, aerospace, defense, instrumentation, and industrial electronics.
With its robust construction and dependable electrical characteristics, RG214 Cable is commonly selected for RF systems that require stable signal transmission and effective shielding in electrically noisy environments.
What Is RG214 Cable?
RG214 Cable is a 50 Ohm double-shielded coaxial RF cable consisting of a central conductor, dielectric insulation, multiple shielding layers, and an outer protective jacket. The coaxial construction maintains controlled impedance while the shielding layers help minimize external interference and unwanted signal radiation.
The cable is particularly useful in RF systems where consistent impedance and shielding performance are essential. It can be terminated with various RF connectors depending on the equipment and installation requirements.
RG214 Cable Construction
The performance of RG214 Cable depends heavily on its layered construction.
Center Conductor
The center conductor carries the RF signal through the cable. A suitable conductive material provides efficient electrical transmission while maintaining mechanical reliability.
Dielectric
The dielectric material surrounds the center conductor and maintains the required spacing between the conductor and shielding. This controlled geometry helps maintain the cable's characteristic impedance.
Double Shielding
One of the defining characteristics of RG214 Cable is its double-shielded structure. Multiple metallic shielding layers improve protection against EMI and RFI compared with cables using a single shielding layer.
This makes the cable useful in environments containing motors, electronic equipment, transmitters, switching systems, and other potential sources of interference.
Outer Jacket
The outer jacket protects the internal cable structure from mechanical damage and environmental exposure. Jacket construction can vary according to the cable design and manufacturer.

Common RF connector families used with coaxial cable assemblies may include SMA, N-Type, TNC, BNC, and other suitable interfaces.
For high-frequency applications, connector quality and assembly workmanship are important because the connector becomes part of the complete RF transmission path.
RG214 Cable Selection Guide
When selecting RG214 Cable, consider the following parameters:
Impedance: Confirm that 50 Ohm impedance matches the connected RF equipment.
Frequency: Verify the required operating frequency and cable performance.
Shielding: Consider the interference level of the installation environment.
Cable Length: Select the appropriate length while accounting for insertion loss.
Connector Type: Match the connector interface to the equipment.
Power Handling: Verify the cable's power capability for the intended application.
Temperature: Check the operating temperature requirements.
Mechanical Installation: Consider flexibility, bend radius, routing, and mounting requirements.
RG214 Cable vs Single-Shielded RF Cable
The primary advantage of RG214 Cable is its double-shielded construction. Additional shielding can provide better protection against external electromagnetic interference and reduce the possibility of unwanted RF coupling.
However, cable selection should always be based on the complete application requirements, including frequency, attenuation, power, flexibility, environmental conditions, and connector configuration.
Why Choose RG214 Cable?
RG214 Cable is a practical option for RF systems that require a combination of 50 Ohm impedance, double shielding, signal integrity, and robust construction. Its shielding characteristics make it particularly useful for installations where interference control is important.
For professional RF systems, the complete cable assembly should be evaluated rather than the cable alone. Connector quality, termination technique, cable length, routing, and installation conditions can all influence overall RF performance.
Conclusion
The RG214 Cable is a double-shielded 50 Ohm RF coaxial cable designed for reliable signal transmission and improved interference protection. Its coaxial construction and shielding make it suitable for telecommunications, aerospace, defense, test and measurement, wireless communication, and industrial electronics.
When choosing RG214 Cable, engineers should evaluate impedance, frequency, attenuation, shielding, power handling, temperature range, cable length, connector type, and mechanical requirements. Selecting the appropriate cable assembly ensures dependable integration into professional RF and microwave systems.
