The OMNI-A0098, OMNI-A0299, and OMNI-A0190 are wideband monitoring antennas covering 20-6000 MHz. They are all supplied in either active with passive bypass or passive versions except for OMNI-A0190 which does not have passive bypass. The antennas have higher gain and sensitivity according to their size where OMNI-A0098 is the largest and OMNI-A0190 the smallest.  For […]

Urban warfare is increasingly important in modern conflicts due to its unique challenges. Densely populated areas with complex infrastructure require effective communication and coordination among war fighters. Secure communication is crucial for the synchronization of assets. Tactical low SWaP COMINT EW equipment plays a vital role in detecting cooperative and uncooperative assets. Alaris Antennas provides […]

Alaris USA provides several different omni-directional antennas designed for high-gain performance in specific frequency ranges. These antennas are suitable for various mounting platforms, such as manpacks and mobile electronic devices. Each antenna utilizes a collinear dipole array radiator with an integrated balun, making it groundplane independent. The antennas are designed for use in extreme operational […]

Monitoring antennas, whether for spectrum monitoring, general receive purposes, ITU applications or signal detection, require wideband performance, high sensitivity in their frequency range and a compact form factor.  From mast to vehicle mounting and more, our range includes active and passive antennas. Here is a selection of our top monitoring antennas: OMNI-A0195 | 20 – 520 […]

This year’s theme at the AOC is the EMSO (Electro Magnetic Spectrum Operation) Playbook. According to the AOC event website: “The EMSO fight will be complex in all future conflicts; it is a critical way we can invest in improving our ability to maneuver in the next five years. The symposium will explore the playbook […]

In a previous article, we showcased some of our C-UAS antennas. Today, we are focussing specifically on the Direction Finding C-UAS antennas. Here’s a quick overview video:   View the DF C-UAS products below: DF-A0095 DF-A0121 DF-A0254 DF-A0257 DF-A0253 DF-A0273 DF-A0020 DF-A0214

Modern naval platforms are some of the harshest electromagnetic environments known to the EW community.  Radars, high-power communications, signal interception and direction-finding systems are all to be installed on the same platform. Normally each of these vying for the highest spot on a severely over-crowded central communications tower with more critical systems always finding their […]

In the first few weeks of this year, there have been several concerning drone strikes in various parts of the world. Some of the most notable ones include the following: UAE oil refinery attack Mexico drug cartel Ethiopia drone attack UK soccer match delay   We have come a long way from the Aerial Target (a small […]

High Frequency antennas play a key role in providing stable, medium to long distance, transmission and reception to tactical operations. Our extensive range of HF omni-directional and directional antennas are designed for mobile, base station and man-portable applications in the 1 MHz to 30 MHz frequency band. These antennas are designed and often customized for […]

Direction Finding Antennas and Accuracy Part 2: Characterization of DF antennas Direction Finding Antennas By Johan Fuhri, Product Owner In the previous blog post we considered some of the ways in which we can express the performance of an DF antenna, and we noted that simply stating the ‘accuracy’ of a DF antenna is not […]

Direction Finding Antennas and Accuracy Direction Finding By Johan Fuhri, Product Owner Part 1: Accuracy and Sensitivity It is sometimes said that: “If you can’t convince them, confuse them!”.  Nowhere is this more apparent than the minefield which is antenna datasheets and brochures. Direction finding antennas are meant to be instrumental in accurately determining the […]

An Introduction to Radio Direction Finding Radio Direction Finding By Eugene Botha and Kalinka Faul Humans do audio direction finding to a remarkable precision of less than two degrees.  Shortly after the development of radio transmitters and receivers, radio direction finding (RDF or just DF) evolved for much the same reasons as human audio direction […]

High Gain Omni Antennas in Mobile Applications High Gain Omni Antennas By Johan Fuhri Antenna Principles High Gain Omni directional antennas are used in situations where the direction of the receiving antenna is not static or known.  A typical situation is where antennas are mounted on a mobile platform like a vehicle or vessel. In […]

Spacing Considerations of Multiple LPDAs on a Mast Multiple LPDAs Written by Johan Fuhri Introduction One of the questions we often get asked at Alaris Antennas, is the question of spacing between multiple antennas on the same mast. Often, this question is related to situations where the space on the mast is limited (mobile or tactical […]

Expecting the Unexpected: High Power Transmit Antennas on Vehicles High Power Transmit Article Written by Johan Fuhri Introduction Many of the Alaris Antennas products are used in vehicle-based high power transmit systems, a typical application being the protection of convoys or VIP transport vehicles against remotely triggered improvised explosive devices (IED)s.  Since the performance of […]
