The Model 8230AJ is a high gain (40 dB) GNSS Anti-Jamming antenna for outdoor conditions. 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. This GNSS / GPS anti-jam technology rejects signals for the lower elevation angles – where most of the interference comes from.
