What are Coax Cables?

Coaxial cables, often referred to as coax cables, are electrical cables that transmit radio frequency signals between two points. They’re best known for their durability and ability to protect data transmission and are easily identifiable by their distinct thick, round shape. They’ve been used since the 1940’s mainly to connect satellite antenna facilities to homes and businesses.

Coax cables are made up of four different layers, including (from inner to outer layer):

  1. A centre conductor of copper wire that data and video travels through
  2. A dielectric plastic insulator
  3. A braided mesh made from copper to shield the cable from electromagnetic interference (EMI)
  4. A thick plastic coating that protects the internal layers from damage

These cables work by carrying data through the centre conductor while the surrounding layers shield any signal lost and reduce EMI. This makes them ideal for television, internet, and radio communications.

In military applications, coax cables must meet strict standards for durability and performance, such as those outlined in MIL-C-17. This is a specification that ensures cables withstand harsh conditions to deliver reliability in critical situations.

Benefits of Coaxial Cables

Reliability

Coax cables are robust and perform well which makes them a popular choice for TV, internet, and telecommunications. Their construction ensures reliable signal transmission, even in challenging environments.

Shielding

Coaxial cables have a much better shielding against interference than other types of cables. They have a layered design that ensures the transmitted signal stays clear and strong – crucial for high-quality audio, video, and data transmission.

Long Distance Transmission

Coax cables can transmit signals over long distances without any loss in quality. This makes them ideal for applications that require signal integrity across a lot of networks.

Cost

The cost of coaxial cables can reduce when buying in bulk, and because the length of the cable can be cut to suit your needs, you avoid waste.

Ease of Installation

Coaxial cable is much easier to install than fibre as it can be installed using simple hand tools regardless of the size of the cable. When installing coax cables, there is only one conductor to deal with, and in the home, the cable can be easily split and extended.

Compatibility

Coaxial cables are highly compatible with a wide range of devices and systems. Their widespread use across different technologies ensures they can seamlessly integrate with different equipment.

FAQs

How does coaxal cable work?

Coaxal cable works by carrying electrical signals between two devices. The central conductor carries the signal whilst the outer shield protects it from external interference.

Can coax cable be used for audio connections?

Yes, it can be used for audio connections. Coaxial digital audio cables used to transmit high-quality audio signals in home theatre systems and professional audio setups.

What changes were introduced in Revision E of MIL-C-17?

Revision E introduced swept frequency measurements for attenuation and VSWR, as well as defined adhesion requirements, improved dimensional stability, and expanded eccentricity requirements to various dielectric materials.

Can MIL-C-17 cables be used in non-military applications?

Yes, MIL-C-17 cables are suitable for a variety of applications beyond the military, including aerospace, telecommunications, and other industries requiring high-performance coaxial cables.

What materials are used in MIL-C-17 cables?

MIL-C-17 cables utilise advanced materials like PTFE, FEP and PFA for jackets which offer high temperature resistance and very strong electrical capabilities where precise, stable measurements are required.
