1210FW

Overview

The Amphenol PCTEL 1210FW is a GNSS and GPS airborne puck antenna designed for through-hole mounting. It operates at a center frequency of 1.575 GHz, covering the 1.565 GHz to 1.585 GHz range. The unit features a TNC female connector and right-hand circular polarization. Key electrical specifications include a VSWR of 2:1 and a gain of 4.5 dB. The antenna body is white.

Feature Summary

• Right-hand circular polarization for optimized signal reception
• DC grounded design for safety and noise reduction
• Airborne-rated construction for aviation environments

Applications

• GNSS navigation systems
• GPS positioning modules
• Aviation aircraft installations

Procurement Notes

Verify the specific datasheet version and manufacturing origin when sourcing this component. Confirm that the TNC female interface matches the system requirements. Ensure the through-hole mounting style is compatible with the PCB layout. Check for any recent supply chain updates from Amphenol PCTEL regarding production availability.

Selection Notes

Select this model specifically for airborne applications requiring right-hand circular polarization. The 4.5 dB gain and 2:1 VSWR are suitable for standard GNSS frequencies. The DC grounded feature helps mitigate interference in sensitive electronic environments. Ensure the physical dimensions fit the designated mounting area on the aircraft structure.
