GPS/GNSS Anti-Jam Antenna
8230 AJ
-
The 8230AJ anti-jam antenna is a high gain (40 dB) GNSS outdoor antenna with a unique conical antenna pattern that rejects interference from the horizon. The antenna rejects signals at lower elevation angles – where most of the interference comes from – and only receives signals from higher elevation angles where the true satellites are. This way, you get all the performance and timing accuracy you would with a standard antenna plus 20 dB or more of interference rejection.It uses a three-stage low noise amplifier, a mid- section SAW, and a tight pre-filter to protect against saturation by high level sub-harmonics and L-band signals. The antenna covers GPS L1, GLONASS L1, BeiDou B1, Galileo E1, and QZSS L1.
