The Differences Between Single and Double Shielded Coax Cables

Coaxial cables are a type of electrical cable that is used to transmit data and signals. They are made up of a central conductor, which is surrounded by a layer of insulation. The insulation is then surrounded by a layer of shielding, which protects the cable from interference. Coaxial cables are used in a variety of applications, including television, radio, and data communications.

There are two main types of coax cables: single shielded and double shielded. Single shielded coax cables have a single layer of shielding, while double shielded coax cables have two layers of shielding. The extra layer of shielding in double shielded coax cables provides additional protection from interference.

Construction

Single shielded coax cables are constructed with a single layer of shielding, which is typically made of copper or aluminum. The shielding is applied to the outside of the insulation, and it is usually held in place by a metal braid or foil.

Double shielded coax cables are constructed with two layers of shielding. The inner layer of shielding is typically made of copper or aluminum, and it is applied to the outside of the insulation. The outer layer of shielding is typically made of a metal braid or foil, and it is applied over the inner layer of shielding.

Performance

The extra layer of shielding in double shielded coax cables provides additional protection from interference. This makes double shielded coax cables a good choice for use in applications where there is a lot of interference, such as in close proximity to power lines or other sources of electromagnetic radiation.

Single shielded coax cables are less expensive than double shielded coax cables, but they do not provide as much protection from interference. Single shielded coax cables are a good choice for use in applications where there is not a lot of interference, such as in a home or office.

Applications

Single shielded coax cables are used in a variety of applications, including:

– Television

– Radio

– Data communications

– Security systems

– Audio systems

Double shielded coax cables are used in a variety of applications, including:

– Satellite television

– Cable television

– Broadband internet

– Telecommunications

– Military applications

Which Type of Coax Cable Is Right for You?

The type of coax cable that is right for you depends on the application you are using it for. If you are using the cable in an application where there is a lot of interference, then you should use a double shielded coax cable. If you are using the cable in an application where there is not a lot of interference, then you can use a single shielded coax cable.

Conclusion

Coaxial cables are a versatile type of electrical cable that can be used in a variety of applications. Single shielded coax cables are less expensive than double shielded coax cables, but they do not provide as much protection from interference. Double shielded coax cables provide additional protection from interference, but they are more expensive. The type of coax cable that is right for you depends on the application you are using it for.
