Coax Loss Calculator

Enter the required engineering values to calculate coax loss with standard RF and radar relationships.

Inputs

Enter your values

Loss per 100 m must be greater than zero.

Cable length must be greater than zero.

Input guide

These are the main values the calculator uses. Keep the units consistent and, where relevant, match the assumptions explained in the related guide.

Input

Loss per 100 m

Unit: dB

Enter the value using the unit shown on the field.

Input

Cable length

Unit: m

Enter the value using the unit shown on the field.

How to use it

Use this page when you need a quick coax loss estimate for RF, radar, or communications planning.

Assumptions and limits

These calculators follow standard engineering formulas. Real antennas, propagation conditions, clutter, and implementation losses can produce different real-world results.
