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. Note that the simple program used for this web page gives a very close approximation for additional losses due to SWR.
