Power Requirements
The Model 3161 Series Octave Bandwidth Pyramidal Horn Antenna is an
efficient transmitting antenna, capable of generating high electric field strengths
using little power. For a given electric field strength, the required power can be
computed using the transmission equation:

The typical power requirements in Watts for a given field strength computed from
the transmission equation for the Model 3161 Series are shown in Table 1
through Table 6. Distance is measured from the aperture of the antenna.
