Datasheet: ASO/AST-1492 Series Cavity Backed Spiral Antennas

Cobham Sensor Systems' ASO/AST-1492 series 2.4-inch diameter spiral antennas provide superior performance for use in applications requiring circular polarization. With excellent input VSWR, these antennas provide smooth broadband gain, low axial ratios and consistent pattern performance. Examples of extensive use include radar warning receivers and other airborne applications. Having undergone rigorous environmental qualification testing, this series of antennas is ideally useful in airborne applications. The ASO/AST-1492 series is available in either left- or right-hand circular polarization, and also with hemispherical radomes.
