The Model AH-220 Horn antenna was specifically designed for radiated EMI measurement over a wide frequency range.
The Horn antenna is a broadband transducer that converts Electric field strength in dBV/m to Volts that can be displayed on a spectrum analyzer or EMI meter.
Setting up using the antenna is described in section 2. Information on the theory of operation is given in section 3. Typical physical and operational characteristics of the horn antenna are given later in this section.
