8171D-HR

Overview

The Amphenol PCTEL 8171D-HR is a dual-band GNSS puck antenna designed for navigation applications. It operates within the UHF frequency group, specifically covering GPS L1 and GLONASS L1 bands with a center frequency of 1.5845 GHz. The unit features a 50 Ohm impedance and a bandwidth of 51 MHz. It utilizes a TNC female connector and is constructed for through-hole mounting. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-band coverage supporting both GPS L1 and GLONASS L1 frequencies
• Proprietary filtering design providing superior out-of-band rejection
• Low-profile puck form factor suitable for external mounting

Applications

• GNSS navigation systems requiring multi-constellation support
• GPS/GLONASS tracking devices
• External mounted navigation antennas

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure correct configuration. Confirm that the required connector type and mounting style match the intended PCB layout. Check for any environmental rating requirements beyond the standard operating temperature range. Ensure compatibility with the host system's RF interface specifications before finalizing the purchase order.

Selection Notes

Select this model when simultaneous reception of GPS and GLONass signals is required in a compact form factor. The low-profile design is ideal for applications where height restrictions apply. Consider the through-hole mounting requirement during the mechanical design phase. Evaluate the need for high out-of-band rejection if the installation environment contains significant RF interference sources.

Part Context

This component belongs to the 8171D series of RF antennas manufactured by Amphenol PCTEL. The series focuses on navigation standards within the UHF frequency range. The 8171D-HR variant specifically addresses dual-band requirements for global navigation satellite systems. It represents a specialized solution for precise positioning applications requiring robust signal integrity.

Replacement Considerations

Consult official substitution lists for compatible dual-band GNSS puck antennas. Verify that any alternative part maintains identical impedance, connector type, and mounting footprint. Ensure the replacement supports the same frequency bands and operational temperature range.
