1. GENERAL INFORMATION
1.1 GENERAL DESCRIPTION
The AR RF/Microwave Instrumentation Model ATH2G8A-1 Horn Antenna is a complete, self-contained unit
that is well-suited for either shielded room or free-space radiated emissions or radiated susceptibility testing
over a frequency range of 2.5–7.5 GHz. The Model ATH2G8A-1 has a power-handling capability of 12
kilowatts (kW) with a nominal gain of 18dB.
This versatile antenna works equally well as a radiator for Radio Frequency (RF) susceptibility testing or as a
receiving antenna for RF emissions testing.
1.2 SPECIFICATIONS
Refer to the AR Data Sheet at the end of this section for detailed specifications and performance curves for
the Model ATH2G8A-1.
1.3 INSTALLATION
Before installing the antenna, thoroughly inspect the unit for signs of any physical damage that may have
occurred during shipment. Read the following operating instructions in their entirety, and pay particular
attention to all CAUTION notes.
1.3.1 Connections
Waveguide losses, especially at the lower and higher frequencies, can be minimized by utilizing low-loss
waveguide. The waveguide should be terminated with a WRD 250 waveguide connector in order to mate
with the WRD 250 waveguide connector provided on the antenna.
1.3.2 Power Amplifier Selection
When used in a shielded room, reflections and room losses will reduce the available microwave (MW) field.
recommends a design safety factor of 100% when selecting a MW power amplifier. Optimum performance
will be achieved when the Model ATH2G8A-1 Horn Antenna is used with a broadband MW power amplifier,
such as the Model 1000T2G8B, and other high power amplifiers in this frequency and power range.
