Antenna
400MHz–1000MHz
The Model ATH400M1G is a high gain horn antenna specially designed for use in RF Susceptibility Testing. Its
high gain characteristics permit achievement of higher electric fields per watt of input power. Exhibiting
generally increasing gain with increasing frequency, the ATH400M1G helps compensate for losses that occur
elsewhere in an RF test system at high frequencies. The Model ATH400M1G is intended for use with the
2000W1000 and other high power amplifiers.

FREQUENCY (MHz)
Field strengths have been measured in free-space conditions. Individual shielded rooms, amplifiers, and test-system conditions will
influence performance. Field strength also varies with frequency and position of antenna and EUT in non-anechoic testing environments.
