The calculator above can be used to estimate the attenuation (dB loss), power
handling capability, and transmission efficiency for some of the more popular
Wireless Communications and MIL Spec cables at the frequency of interest (below Cutoff Frequency).
Actual measured values may vary somewhat from the calculated numbers based on
manufacturing tolerances, cable length, connectors, operating frequency, and
measurement accuracy. The attenuation of cables with Bare Copper and Tinned Copper outer conductors can vary substantially from the theoretical value due to oxidation and therefore we recommend they not be used above 1 GHz. Note: the outer conductor of LMR cables is the aluminum tape.
Using the Calculator
1.) Select the product of interest using the Drop Down box.
2.) Enter the frequency of interest in MHz.
3.) Enter Run Length in feet.
4.) Click Calculate button.
5.) Repeat steps 2,3, & 4 for various frequencies and cable lengths.
