Cable loss calculator

Coaxial cables play a crucial role in the overall performance of a 4G or 5G Antenna. The signal loss or attenuation can greatly affect the antenna signal strength. This signal loss is an important factor to consider when selecting a coaxial cable.


Here’s a quick line loss calculator to use. Select the line type, line length, frequency, load SWR and power input, then click “Calculate”:
