Alaris Antennas

Alaris Antennas (Defence and Specialised) designs, manufactures and distributes antenna products for the global defence, homeland security and specialised antenna market sectors.

Our clients are mostly international Electronic Warfare (EW) system houses, but also include semi- and governmental organizations. Our esteemed clients use our products for military defence, security, VIP protection (commercial) and general communication markets.

A new segment that the company has entered into is the Test and Measurement field, with the DF-A0047. We typically sell through distributors / agents in countries where it is difficult to work directly, due to barriers of language, culture or business practices.

The market continuously demands increased frequency band widths. Alaris Antennas is well qualified and focused in this regard. Our competitive advantage is that we offer unique products through technical competency and excellent service.

We assist our clients to win their contracts by giving them a cutting-edge advantage through superior antenna technology. We strive to partner with our clients and tailoring solutions to their needs, thereby achieving outstanding results.




We have an extensive range of HF, VHF, UHF and SHF (L-, S- and Cband) omni-directional and directional communications antennas, designed for mobile, base station and man-portable applications, point-topoint and point-tomultipoint radio communications.



Direction Finding

A direction finding antenna is used in spectrum monitoring, ITU applications, transmitter fault finding and EW systems to establish the direction from which a received signal was transmitted. We design and manufacture direction finding (DF) antennas of all sizes, for all applications. We have been constructing and testing direction finding antennas for over a decade.

These antennas come in a range of different sizes from briefcase carried hand-operated DF antennas to large mast-mounted arrays. Between these two extremes lie a series of vehicle, tripod, helicopter, ship and submarinemounted antennas.



High Power Transmit

Alaris Antennas offers a range of antennas for stand off jamming, antenna testing and high-power transmit applications. Typically, these are used to prevent unauthorised communications from functioning, either by preventing communications entirely or by introducing spurious messages into the communications system. Antennas that cover public broadcast bands can also be used to establish temporary or permanent broadcast facilities to disseminate information to the general public.




Alaris Antennas designs and manufactures monitoring antennas for a range of applications. 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. Our range includes active and passive antennas.




Alaris Antennas designs and manufactures a range of electronics products, passive and active, to complement our product range. These include RF switches, antenna tuning units, multi-channel gain blocks, power supplies, filters and diplexers. Some antenna products, such as active antennas and direction finding systems are integrated with electronics in accordance with the particular application.




Alaris Antennas has partnered with leading manufacturers of RCIED jamming equipment to provide suitable antennas in manpack and vehiclemounted configurations. Radio frequency jammers provide the best defence against radio-triggered IEDs. Because of the extremely broad range of frequencies that are used to trigger RCIEDs, an effective wideband antenna system is essential to ensure the best possible protection.



Test And Measurement

Alaris Antennas designs and manufactures a range of products for use in test and measurement applications. Example applications where these products are in use are for handheld interference hunting and direction finding.
