Noted for its wide bandwidth and low susceptibility to interference, coax cables, as well as RF cable assemblies, are commonly used for data communications. Even though one coaxial cable assembly will appear to be virtually identical to the next, rarely is that the case. Trade designations generally refer to the cable’s electrical characteristics; specifically the impedance of the cable.
Coax cable types (RG142, RG400, etc.) should not be mixed – they have differing levels of impedance and mixing them may degrade system performance. Equally important is the quality of the cable itself. A poorly manufactured cable can ruin the transmission, too. Casco takes all this into consideration when manufacturing coaxial cable assemblies and delivers only finished product that meets your exact specifications and our exact quality standards.

Understanding the Components of Coaxial Cable Assemblies
Coaxial cables are relatively simple in their design, consisting of four main components. At the core is a single copper wire that serves as the main conductor for the signal. Around that wire is an insulating layer of dielectric material that protects the integrity of the signal and prevents it from leaking out of the cable. This is typically made of plastic, solid polyethylene or sometimes a hollow section that allows air or another gas to be used as the insulator. Surrounding these elements is another layer of metallic materials that acts as a shield against outside interference. The entire assembly is wrapped in an exterior layer of plastic material to provide additional insulation.
Selecting the Right RF Connectors for Your Needs
Our expertise in RF coaxial cable assembly means we can help you find the connections that make the most sense for your needs. Because each cable type has its own unique set of specifications, understanding your application’s needs is crucial for getting the best performance from your cable assemblies. Working with our experts means we will help you determine the best option given the operational frequency of your signal, the connector type used by your equipment, frequency range, any special environmental conditions and other factors.
Testing and Ensuring Signal Integrity in Coaxial Cables
To test the strength of signals coming through your coax cables, you typically need a tool such as a spectrum analyzer or signal strength meter. These devices can be connected to the output end of the cable to test the quality of the signal.
If you want to ensure you get the highest-quality signal from your cabling, the best place to start is by choosing the right cable for your specific requirements. Beyond that, it’s important to make sure and bends or kinks in the cables are kept to a minimum, and that the cables have the appropriate shielding for their surroundings. You also should take care to visually inspect your cabling on a regular basis to ensure there are no cuts or areas of missing insulation.
