Model 8739-800 - X-Band, 4-foot Tracking Antenna

This antenna incorporates a four foot parabolic reflector and a prime focus tracking feed. The feed is vertically polarized. Gain is 38 dBi, isolation is better than 30 dB and the operating frequency band is 9.1 - 9.3 GHz. Two-plane monopulse tracking is provided by an integral waveguide comparator/feed. The sum, elevation and azimuth difference ports are SMA jack connectors.

Model 9033-810 - X-Band, 4-foot Tracking Antenna
Identical to Model 8739-800. Modified reflector interface; RF cable assemblies added.

Model 8467-801 - Five-Element Monopulse Feed

This feed system uses a central radiating element for the sum channel and four outer elements fed from a switch/hybrid comparator subassembly to form the difference patterns. Polarization is switch-selectable right-hand and left-hand circular in the 1500 - 1750 MHz frequency band. The feed includes a 1.5 dB noise figure low noise amplifier. RF port is a type N jack.

Model 8467-802 - Five-Element Monopulse Feed

Similar to the Model 8467-801, this feed operates over the telemetry frequency band of 2100 - 2300 MHz and includes a 1.5 dB noise figure LNA as part of the feed assembly. Polarization actuation for these types of feeds uses 24 VDC transfer switches. Both the Model 8467-801 and -802 feeds can be supplied with a remote switching panel containing LNA bias switch, power supplies, polarization switching and indication circuits.

Model 8905-800 - C-Band Monopulse Feed

This feed system is designed for optimum sum and difference illumination of a large reflector with an F/D ratio of 0.50. It is linearly polarized and operates over the 4.1 - 4.6 GHz frequency band. A central scalar horn aperture is used for the sum channel. Difference patterns are synthesized through two Wilkinson-type power dividers connected to two pairs of dipoles located near the edge of the scalar horn. The resulting feed patterns exhibit excellent sum gain and sidelobes with high error channel slope. RF ports are SMA jacks.

Model 9170-800 - X-Band Cassegrain Monopulse Antenna

This 4-foot parabolic antenna which has been designed for helicopter environments. The X-Band antenna consists of a graphite-epoxy honeycomb reflector and a 9.1 - 9.3 GHz Cassegrain monopulse tracking feed.

This complex L/S-band telemetry-tracking feed system provides a minimum G/T of +22 dB/K when used in a 10 meter reflector. The transmit feed port can handle 500 - 1,000 watts CW. Its dimensions are 20 inches diameter and 58 inches long with a weight of 160 pounds. Monopulse tracking in provided in two channels using four feed elements. The system includes a monopulse scan converter, all RF filters, LNAs, downconverter and extensive BIT provisions. The complete feed system is fully sealed and can be pressurized to 1 psig. Extensive product support and documentation is available for this high-performance feed system.
