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.

Directional Couplers
Pasternack directional coupler category is passive devices that couple part of the transmission power in a transmission line. Our directional coupler series provides the bandwidth, high directivity and higher power that engineers need for their most demanding application designs. RF directional couplers often use two transmission lines set close together so that energy passing through one is coupled to the other. Many Pasternack directional coupler components are RoHS and REACH compliant. RF directional couplers are available with 4.1/9.5, 4.3-10, 7/16 DIN, Type N or SMA connectors. Our directional coupler line has 6dB, 10dB, 15dB, 16dB, 20dB, 30dB or 35dB coupling values. Power ratings of our typical and high power directional couplers range from 25 Watts to 70 Watts. Directional coupler frequency range of this product design is from 1 GHz to 8 GHz. As with our other over 40,000 RF, microwave and millimeter wave components from Pasternack, this directional coupler series is in-stock. Not only are these couplers in directional design in stock, they also will ship the same day as they are purchased.

Cassegrain Antennas
In telecommunications and radar, a Cassegrain antenna is a parabolic antenna in which the feed antenna is mounted at or behind the surface of the concave main parabolic reflector dish and is aimed at a smaller convex secondary reflector suspended in front of the primary reflector. The beam of radio waves from the feed illuminates the secondary reflector, which reflects it back to the main reflector dish, which reflects it forward again to form the desired beam. The Cassegrain design is widely used in parabolic antennas, particularly in large antennas such as those in satellite ground stations, radio telescopes, and communication satellites.
