There are two main types of coaxial cables ones with an impedance of 75 Ohm (Ω) and ones with an impedance of 50 Ohm.
For more information, please visit our website.
Cables with 75 Ohm are mostly used for video signals, while 50 Ohm cables tend to be used for data and wireless communications.
In coaxial cables, Ohm refers to the impedance, which is the measure of resistance in the cable to the flow of electrical energy.
RF coaxial cables are used to carry radio frequency signals. Theyre the standard input cable on TVs and feature a single pin that plugs into the RF input on a device.
RG-6 cables have larger conductors, so they provide better signal quality. They have thicker dielectric insulation and are made with a different kind of shielding, allowing them to handle GHz level signals more effectively. As this type of cable is thin, it can also be easily installed in walls or ceilings.
A common cable in domestic settings, RG-59 cable is similar to the RG-6, but it has an even thinner centre conductor. This makes it a good choice for short runs and low-frequency transmissions.
RG-11 cable is easily identifiable as its thicker than other types of coaxial cable, which can make it more difficult to work with. However, it offers a lower attenuation level than RG-6 or RG-59, meaning it can carry data for longer distances.

Getting your home or small business network in place is easier than you might think. The primary obstacle for many is identifying what tools you'll need to complete the task. Our Cable Academy has many resources on different aspects of choosing a cable and steps needed to complete your installation.
These are the basic tools to get you started. trueCABLE now offers many of the cabling tools. For the others, we recommend Amazon or your local hardware or home improvement store. Because different termination options require their own specific tools, we have listed termination tools in their own section. Other installation and construction tools are listed in the sections that follow.
