PCTEL’s GPS/GLONASS High Rejection Time Sync Antenna is a dual-band antenna covering both GPS L1 and GLONASS L1 frequencies. PCTEL’s proprietary filtering design allows wideband coverage while achieving superior out-of-band rejection. This antenna comes in a small, conical form factor to minimize perching and provide runoff. The temporary mount model (8171D-HR-DH-W) is equipped with a TNC female connector, while the permanent mount models (8171D-HR-NDH-W) has an N-Male bottom-fed connector. This antenna is ideal for any global GPS/GLONASS time synchronization application that requires an externally mounted antenna.
