About this deal
When selecting a coaxial connector, you will need to know the key parameters of the cable you plan to connect. These include:
Your installer will typically apportion the cable into shorter lengths to cover the range of the installation while maintaining quality signal strength. 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. What’s RF coaxial cable?
Signal loss doesn’t end there. Mixing and matching 50 Ohm and 75 Ohm cables and systems (more on this later) can lead to further signal loss. While you can customize your installation with connectors and adapters, it's best to stay consistent.Coaxial cable works by carrying data in the centre conductor, while the surrounding layers of shielding stop any signal loss (also called attenuation loss) and help reduce EMI.
