This is a COAX Cable Attenuation chart based on the coax type and frequency. It is very helpful to design and calculate losses within any Coaxial RF distribution system.

Attenuation data helps in understanding how much signal loss occurs per unit length of cable at various frequencies, which is crucial for ensuring that the signal strength remains above the required threshold for the system's intended application. This is especially important for long cable runs or for frequencies where the cable type exhibits higher losses.
In designing an RF distribution system, one would typically use such a chart to:
-
Select the appropriate type of coaxial cable: Depending on the frequency of operation and the allowable signal loss, a designer would choose between types such as RG-59, RG-6, or RG-11.
-
Calculate total losses: By multiplying the attenuation per unit length by the total cable length, the total expected signal loss can be estimated.
-
Determine the need for amplifiers: If the signal loss is too high, inline amplifiers might be needed to boost the signal at certain points in the cable run.
-
Budget for connectors and splices: Each connection or splice in the cable can add additional loss, which needs to be considered in the overall loss budget.
-
Assess the impact of temperature: Since attenuation can vary with temperature, it's important to consider the environmental conditions in which the cable will operate.
