Loss of Coaxial Cables
The table shown gives typical values for RF loss in several popular coaxial cables in the 100-1000 MHz range. Values are typical and may vary with the manufacturer, condition, and age of the cable. They are a good starting point for estimating loss in a planned cable installation or application.
| Cable Type |
