Antenna factor when properly applied to a field strength meter reading yields:
- electric field intensity (V/m)
- magnetic field intensity (A/m).
The field intensity in the far-field radiation pattern of an antenna:
- Is proportional to the square root of the effective radiated power. Increasing the effective radiated power four times , the field intensity will be doubled.
- Is direct proportional to antenna current. If the far-field intensity in the far-field antenna pattern is doubled the antenna current will increase 2 times.
