The AU-217 from Furuno is a Multi-GNSS Antenna for GPS (L1 band) and GLONASS (G1 band) reception. This right-hand circular polarized antenna delivers a gain of over 3 dBi and has a VSWR of less than 1.5:1. The antenna assembly consists of a patch antenna for receiving GNSS signals and a preamplifier for signal amplification that requires a DC power supply from 2.5 to 16 V.
The device features a built-in noise filter that makes it ideal for use in a location with an intense electric field. This highly noise-resistant and environmentally resistant (equivalent to IP67) antenna is available with a TNC (F) connector and is suitable for use with GT Series timing GPS/GNSS receiver modules and GF Series GPS/GNSS disciplined oscillators. It can be used with an optional antenna fixing bracket for easy installation.
