Overview
Field strength generated under free space conditions at a separation from the antenna tip (see diagrams for several combinations of power and distance). If environmental reflections are present, this may lead to frequency and height dependent field strengths. The power figures refer to a 50 W source and an unmodulated (cw) signal. An 80% Amplitude Modulation requires a 1.8 times higher voltage, resulting in 3.24 times higher power compared to cw. A field strength increase of factor 10 requires 100 times amplifier-power.
The safety precautions and relevant standards must be considered while performing tests with high field strength! Ignoring these standards and precautions may result in severe danger for health!
