Antenna Research Associates, Inc. (ARA) products

The ARA-3240 Series hosts extremely rugged and portable high-gain UHF SATCOM antennas that are available in full and compact sizes. These antennas are ideal for tactical command posts and temporary fixed site applications. The compact version is ideal for operation in high winds. The right-hand circular polarized (RHCP) antenna is designed to operate from 240 to 318 MHz at 200 Watts CW. These antennas are designed with exceptionally high gain, low VSWR, and rapid deployment. The antenna complies with MIL-STD-810G environmental standards for vibration, shock, temperature, loose cargo, and immersion.

ARA has a wide variety of Prime-Focus, Offset, Gregorian, and Cassegrain feeds and antennas for multiband applications. These multiband feeds are designed to minimize phase center movement. This helps to better focus the feed within the reflector for optimal gain, providing the highest possible EIRP and G/T. ARA designs, simulates, manufacturers, and tests all feed solutions in-house which can support FCC, ARSTRAT, and other applicable standards. ARA utilizes its fully staffed, Middleborough, MA outdoor test range to go beyond bench tests to ensure all specifications are met. ARA also offers reflectors, positioners, and controllers to support antenna subsystems. This product family supports customer SATCOM Terminals and Ground Stations to enable connectivity to multiple constellations and networks without changing hardware.

The ARA-1220 and ARA-1220-101 antennas are wide band, omni- directional, vehicular communications antennas. The ARA-1220 and ARA-1220-101 are designed for use in the most demanding and harsh tactical conditions. The lightweight, low-profile construction combined with a standard NATO 4-Bolt mounting pattern allows it to be easily integrated into military vehicles and most antenna mast systems.

ARA’s series of log-periodic antenna arrays supports a wide variety of applications requiring high-power transmission. These arrays are designed to meet strict beamwidth, gain, and power handling requirements. The log periodic design produces very broadband characteristics and a unidirectional radiation pattern. These antennas can be used to make accurate electric field strength measurements and an individually calibrated antenna factor curve can be provided.

Understanding weather patterns is an important tool for public safety and agriculture to ensure that the proper steps are being taken before storms. Properly monitoring weather patterns helps with preparation to limit damage and administer the proper size of response needed during and after major weather events. This is critical for public safety.

The Vehicular Spectrum Operations Series of antennas are broadband monopoles designed to operate over a wide frequency range to support passive and active applications with low VSWR. These antennas exhibit exceptional gain in an omni-directional pattern. It is designed with compliance to the strictest military specifications, to include MIL-STD-801F environmental procedures. This series of antennas are mounted in a sealed dielectric radome to offer mechanical stability and isolation from environmental hazards and offer superior power. The antennas are available with a magnetic mount for rapid installation on various vehicles or with a spring base featuring the NATO bolt pattern.

ARA's C-UAS system is outfitted with cutting-edge sensors and technologies that enable remote detection, tracking, and identification of small, unmanned aircraft systems (UAS). It can also disrupt activity when necessary. Our Anti-Drone products can be used to protect vital infrastructure from possible risks posed by UAS-based terrorist attacks or espionage, both in remote and urban locations. Moreover, C-UAS works as a ground surveillance system in addition to offering thorough airspace coverage.

Munition Seeker/Multifunction Sensor (SBIR). Proprietary Tightly Coupled Dipole Array (TCDA) Architecture. Wide Bandwidth with high efficiency and excellent scan performance. Scalable in size/shape/frequency of operation. Lower Profile than competing designs.

The Tactical IFF system is a lightweight, portable four-panel compact IFF interrogator AESA. It is a short-range (200 km) short-range air defense (SHORAD) system. With only eight elements to the system gives and its low cost and SWaP, this gives the system a tactical portability and reliability when compared to rotating mechanical systems. The beamwidth is steerable in azimuth to +/-45° with the capability of reaching +/-50°. This system integrates with the customer’s primary radar system and is interrogator agnostic. SUM and DIFF patterns are provided simultaneously via 2 RF connectors.
