## Fresnel Zone Radius Calculator as per Equation-1

This page of converters and calculators section covers Fresnel Zone Radius Calculator. It calculates fresnel zone which allows optimum performance of the wireless link between two LOS antennas. It provides two calculators as per two equations of fresnel zone radius.

Distance between two antennas in Km (input1) :

Frequency of operation in GHz (input2) :

Fresnel Zone Radius in Meters (Output1):

80% of Fresnel Zone Radius (Output2):

INPUTs:
Distance = 10 km, Frequency = 2.4 GHz
OUTPUTs:
Fresnel Zone Radius = 17.67 meters , 80% of Fresnel Zone Radius = 14.14 meters

### Fresnel Zone Radius Calculator as per Equation-2

Distance between two antennas in Miles (input1) :

Frequency of operation in GHz (input2) :

Fresnel Zone Radius in Feet (Output1):
