Attenuation CalculatorAlthough typical and maximum attenuation values at discrete frequencies may be found in Harbour's online catalog, this Attenuator Calculator makes it easy to compare multiple items at any operating frequency. Just type a frequency in MHz (for instance 18 GHz = 18,000 MHz) to calculate and compare typical attenuation values.
