Datasheet: ASO/AST-1503 Series Cavity Backed Spiral Antennas

Cobham Sensor Systems' ASO/AST-1503 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. This series of antennas has undergone rigorous environmental qualification testing for use in airborne applications and are available with either SMA Female connector (ASO-1503) or TNC Female connector (AST-1503).
