The Model ATH200M1G high-gain horn antenna exhibits increasing gain with increasing frequency (up to 18dB at 1000MHz). With this useful performance characteristic, the antenna helps compensate for losses that occur elsewhere in an RF test system – losses that generally increase with frequency. The Model ATH200M1G is well suited for either shielded room or free space testing. Optimum performance is achieved when it is used with our Model 2000W1000 or for even higher fields, our Model 3000W1000 broadband amplifier for RF susceptibility testing. In shielded rooms, reflections and room losses may reduce the available field. AR suggests a design safety factor of 100% in the selection of power amplifiers.
