This calculator is used to predict the theoretical attenuation between two antennas in free space by entering the distance, frequency, and antenna gains.

Distance: | |

Frequency: | |

Transmit Antenna Gain: | |

Receive Antenna Gain: | |

d = Distance between the antennas.

F = Frequency

G (Tx) = The Gain(dBi) of the Transmitting Antenna.

G (Rx) = The Gain(dBi) of the Receiving Antenna.

c = Speed of light in vacuum (Meters per Second)

- Our Antenna Beamwidth Coverage Calculations is a unique tool to assit in calculating the maximum coverage based on antenna half-power beamwidth.
- Here is a field intensity calculation calculation tool to help determining the actual field intensity or power density at a given distance
- Antenna Factor and Gain Calculations
- Useful formulas for RF related conversions
- dBm to Volts to Watts conversion

- 18 GHz to 40 GHz
- Precision machined, Rugged Construction
- Broadband High Frequency

High gain, low VSWR, and rugged design make this dual ridge horn antenna excellent for both immunity and emissions testing.

This tool will calculate the maximum coverage that the antenna will cover from a specified distance and antenna's half-power beamwidth. [more...]
