Product Details
The SINU2000-LP is a compact cavity-backed 2-arm sinuous antenna that delivers linear polarization continuously from 2 to 15 GHz from a single element. Its cavity-backed, unidirectional pattern and wide, symmetric E- and H-plane beams (roughly 130° at −10 dB) make it well suited to electronic warfare, ES/SIGINT, spectrum monitoring, and broadband test and measurement. Its small footprint and low weight (2.5 in diameter, 60 g) make it easy to platform-mount. Each antenna is built around a PCB sinuous element in an anodized-aluminum cavity; polarization is linear, with the plane set by the mounting orientation. The antenna feeds through an SMA female connector and handles up to 10 W of input power.
- Suited to electronic warfare, electronic support measures and signals intelligence (ES/SIGINT), spectrum monitoring, and broadband test and measurement.
- Cavity-backed 2-arm sinuous design gives a unidirectional pattern and continuous operation across the full 2 to 15 GHz range.
- Wide, symmetric E- and H-plane beams (~130° at −10 dB) provide a broad angular field of view.
- Compact and lightweight (2.5 in diameter, 60 g) for straightforward platform mounting.
- Linear polarization with well-matched VSWR; SMA female connector with #10-24 mounting; handles up to 10 W. Each unit ships with a measured test report of VSWR and boresight gain.
