Overview
The Amphenol PCTEL 8171D-HR-DH-W is a dual-band GNSS dome antenna designed for high-rejection time synchronization 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 operational range spans from 1.574 GHz to 1.607 GHz. The unit features right-hand circular polarization (RHCP) and utilizes a TNC female connector for interface. Mechanical specifications include a pole mount configuration with a ground plane size of 44 mm. This component supports Beidou, Galileo, GLONASS, and general GNSS signals.
Feature Summary
- Proprietary filtering design enabling wideband coverage with superior out-of-band rejection
- Dual-band capability supporting both GPS L1 and GLONASS L1 frequencies simultaneously
- High-rejection architecture optimized for precise time synchronization requirements
Applications
- GPS timing reference systems
- Aviation special purpose navigation
- GNSS base station installations
- Time synchronization infrastructure
Procurement Notes
Verify that the specific ordering suffix matches the required connector type and mounting style. Confirm RoHS compliance status if environmental regulations apply to your project. Ensure the TNC female interface is compatible with existing cable assemblies. Cross-reference the part number against official Amphenol PCTEL documentation to avoid substitution errors with similar series models.
Selection Notes
Choose this model when high out-of-band rejection is critical for maintaining signal integrity in noisy RF environments. The dual-band support makes it suitable for multi-constellation positioning needs. Consider the pole mount form factor for outdoor or rooftop deployments where structural stability is required. Verify that the 44 mm ground plane dimensions fit within the available installation space constraints.
Part Context
This component belongs to the 8171D series of RF antennas manufactured by Amphenol PCTEL. It is categorized under Navigation RF standards and falls within the UHF frequency group. The product status is listed as Active, indicating ongoing production and availability. It serves as a specialized solution for GNSS applications requiring precise timing references rather than general-purpose data reception.
Replacement Considerations
The part number 8171D-HR-NDH-W appears in related listings but features an N-type connector instead of TNC. Verify connector compatibility before considering any substitute. No other direct functional equivalents are confirmed in the provided documentation.
