91121402

Overview

The Huber+Suhner 91121402 is a SENCITY SC Logarithmic-Periodic Antenna designed for specialized communication applications. It operates within the frequency range of 1 to 18 GHz, providing consistent performance across this broad spectrum. The antenna delivers a gain of 9.2 dBi at 1 GHz, 9 dBi at 6 GHz, and 8.7 dBi at 18 GHz. It maintains a Voltage Standing Wave Ratio (VSWR) of 1.5, ensuring efficient signal transmission. The unit features a female chassis mount interface and is constructed for durability in demanding environments.

Feature Summary

• Logarithmic-periodic design ensures stable electrical characteristics over a wide bandwidth
• High gain output optimized for long-range directional communication links
• Robust chassis mounting configuration suitable for fixed infrastructure deployment

Applications

• Specialized point-to-point communication systems
• Directional radio link installations requiring high directivity
• Secure military or government communication networks

Procurement Notes

Verify the specific frequency band requirements against the 1–18 GHz operational range before ordering. Confirm that the chassis mounting dimensions align with the installation site specifications. Ensure compatibility with the required connector type and polarization for the intended system integration. Cross-reference the gain specifications at critical frequencies to validate performance expectations.

Selection Notes

Select this component when a wideband logarithmic-periodic solution is required for fixed communication setups. The 9.2 dBi gain supports extended range applications compared to standard omnidirectional units. Consider the chassis mount form factor for permanent installations rather than portable use cases. Evaluate the VSWR performance to ensure minimal signal reflection in high-frequency operations.

Part Context

This antenna belongs to the SENCITY SC product line, which focuses on secure and reliable communication solutions. Huber+Suhner manufactures these components for industrial, transportation, and communication markets. The SENCITY series emphasizes high reliability and long service life under harsh environmental conditions, supporting global connectivity standards.

Replacement Considerations

No public confirmed substitute part numbers are available for this specific logarithmic-periodic antenna model. Direct replacement requires matching the exact frequency range, gain profile, and mechanical mounting interface. Consult official distributor catalogs for equivalent wideband directional antennas if this specific SKU is discontinued.
