Calculate Antenna Field Strength

Antenna Field Strength can be calculated for a particular point, given the antenna height, power output and the distance from the antenna.

Antenna field strength relatively close to an antenna is measured in volts per metre and can be reasonably estimated from the effective height of the antenna, the RF power into the antenna at a known impedance, the operating frequency, and the distance from the antenna.

Units are in either Meters (Metric) or Feet (USA/Imperial).

Provide the Effective antenna height, power at antenna (W), antenna impedance, frequency, and distance from antenna.
