Rugged antenna system conquers harshest ocean environments

Keeping our oceans safe is not an easy task even for the best-engineered high-tech hardware.

Antennas need to cope with some of the world’s harshest and most isolated ocean environments. Intense cold, extreme corrosion, ice, rain, hail, vibration and the constant jarring force of the waves must all be overcome on a daily basis. Added to this is the requirement for maximum product reliability, given that shore-based workshops and specialist technicians are far away.

These are among the challenges being successfully met by South African-based Alaris Antennas, a designer and manufacturer of high-technology antennas. Among Alaris’ most successful products is the DF-A0037, a direction-finding antenna in service with naval peacekeeping forces from Europe, Asia and Australasia. It is capable of monitoring signals and tracking their direction of source (direction finding) in the high frequency (HF), very high frequency (VHF) and ultra-high frequency (UHF) bands. The product is used in applications such as intelligence gathering, counter-piracy, counter-smuggling, deterring illegal fishing and general security tasks.

The DF-A0037 was first unveiled in 2010 and, according to Alaris Holdings CEO Juergen Dresel, continues to be refined and customised to meet the requirements of each naval customer.

“It is a mature, proven product that is in great demand and we see strong future potential in markets such as the United States and South America. It is also under consideration by South Africa,” he says. “We have filled a niche in which we have a market-leading expertise and a solid track record. The DF-A0037 requires more than just antenna knowledge. It entails wider system knowledge so that, on a naval vessel, the competing frequencies of other equipment can be filtered out to enable the product to operate at maximum efficiency. This necessitates specialist know-how in which we have a strong competitive advantage.”

The DF-A0037 was originally developed as a land-based mobile direction-finding antenna system , but later modified for the more demanding maritime environment. Key specifications include:

  • DF frequency range: 1 – 3600 MHz
  • DF Type:                    Five element correlative interferometer
  • Number of frequency bands:         Three
  • Monitoring frequency range:          1 – 3600 MHz
  • Mechanical design:     Hardened for harsh maritime environments

Using the core competencies in research and development, engineering and manufacturing possessed by its operating companies – Alaris Antennas (South Africa) and COJOT (Finland) – Alaris Holdings provides electronic peacekeeping and communication products for a variety of applications. These include electronic counter-measures to prevent the remote detonation of bombs, jamming of enemy communications, monitoring of enemy communications and signal direction finding. The products may be mounted on vehicles, aircraft, drones, ships and submarines, or carried by individuals.

In the civilian environment, the company’s technology is used by test and measurement businesses and frequency regulatory bodies.

Alaris Holdings acquires United States based company mWave Industries, LLC

[Centurion, 2 October 2018] –  Alaris Holdings is a technology holding company listed on the JSE AltX since July 2008. The company announced today that an agreement was signed between Alaris Holdings and United States based company mWave Industries, whereby Alaris  acquired mWave.  Alaris  confirmed that it applied for and received  unconditional CFIUS (Committee on Foreign Investment in the United States) approval from the US Government to go ahead with the acquisition.  The final closing requirements were concluded on 30 September 2018 and the acquisition takes effect from 1 October 2018.

The Alaris Holdings Group consists of Alaris Antennas (South Africa) and COJOT (Finland). The Alaris strategy is built on three pillars, namely radio frequency technology, owning intellectual property and global presence. One of the main objectives for Alaris is to expand its footprint globally. The US market is the largest defence market in the world representing approximately 60% of the global market. The US administration has for the first time in a few years, voted for and approved an increased defense budget to the amount of about $716 billion for 2019.

Alaris Antennas, a subsidiary of Alaris Holdings and with its head office in Centurion (South Africa), designs, develops, manufactures and sells specialised broadband antennas as well as other related radio frequency products. Its products are used in the communication, frequency spectrum monitoring, test and measurement, electronic warfare and other specialised markets. Clients are located across the globe, mostly outside of South Africa (the Americas, Europe and Asia). Its clients are system integrators, frequency spectrum regulators and players in the homeland security space.

Alaris has grown annual turnover and profits consistently since its establishment in 2005. The competitive advantage for Alaris Antennas is its ability to develop and hold its own IP as a result of its client centric model. Approximately 90% of the company’s revenue is derived from exports, which provides a strong justification to increase the Group’s footprint globally.

mWave Industries, LLC is based in Windham, Maine in the United States and is a leading global provider of innovative custom and commercial microwave antenna solutions with special focus on 60, 70, 80, 94 & 110 GHz Millimeter Wave Reflector Antenna.  Their microwave antenna brands include the industry leading Mark Grid, Gabriel, mWave and Quickfire lines of terrestrial microwave antenna which are recognized worldwide for their robust designs and reliability.  The company was established in 2004 and designs and manufactures standard and custom microwave antenna products for commercial and government applications spanning the scientific, defence, and academic communities.

mWave specializes in parabolic grids, solid parabolic and directional panel antenna as well as feeds including conscan and monopulse designs. mWave’s additional product offerings consist of micro-strip arrays, panels, horns, helices, sectors, omnidirectional antennas and waveguide arrays. mWave maintains a fully equipped antenna test range that is used to verify new antenna designs and for production verification and third-party testing for its customers.

COJOT was founded in 1986 and is located in Espoo, Finland. The company has 30 years of experience in the design, development and manufacture of innovative antenna products, serving military and public safety markets globally. COJOT develops innovative broadband antennas to improve connectivity, coverage and competitiveness of radio equipment which is deployed to save lives and protect property.

The company offers reliable and durable antenna equipment, which are designed to function in some of the most demanding environments throughout the world. A trend in the antenna technology field is that of smart antennas. The Group’s engineers are well-positioned to drive this trend, creating products that allow functions like automatic frequency tuning, switched beam antennas and multiple port antennas.

According to Group CEO of Alaris Holdings, Juergen Dresel, and major shareholder of mWave, Peter V. Anania who will be nominated to serve on Alaris Holdings’ Board, negotiations were focused on creating an environment which will have strategic benefit to both organisations.  “The product lines complement one another and by joining forces, the companies will be able to provide an expanded product portfolio and improved service to customers, “says Dresel.

Companies within the Group are strongly focused on research and development and hold exploitable patented technologies that can be monetized into the future. mWave’s extensive experience in design and strong specialisation focus, will add value to the Group’s competitive features and will enable an increased performance and product offering to the customers.

With the background of the three companies in the Group, it is expected that the fostering of design innovation and continued pursuit of novel technologies will be enhanced through the sharing of ideas and talent in these organisations.

“Being a client-centric organisation with clients based worldwide, the Group’s strategy was to expand its global footprint in order to be closer to its clients. With the acquisition of mWave, this objective becomes a reality,“ says Dresel.

Further, Dresel says, “We are very pleased to welcome Peter Farnum, Managing Director of mWave Industries, as part of the Group’s management team moving forward.” Peter holds a Mechanical Engineering degree from the University of Maine, US and has extensive experience in the telecommunications industry.  He further stated that, “It is a privilege to have a high calibre management team at mWave, who are well experienced, hold specialised engineering skills and who shall assist in driving the company forward.”  Part of this team is Chris Mosher, Chief Technical Officer and senior engineer with 20 years’ experience in RF antenna development and Michael Cahill, Vice President Sales & Business Development, being highly successful in selling predominantly into the telecoms market.

“Since the market in the US holds significant opportunities and international expansion is an important part of the Group’s global strategy, we are confident that this acquisition will not only provide increased benefits to our customers, but will improve shareholder value as well,” says Dresel.

Alaris’ New ESS Equipment Up and Running

Alaris Antennas has recently acquired and installed specialised ESS equipment, which will allow us to conduct a number of various environmental tests in-house.

The new equipment was designed, manufactured and installed by a South African company and consists of a walk-in temperature and humidity chamber as well as two vibration tables.

Environmental Stress Screening, or ESS, is a method used to identify possible product failures which are likely to occur in the actual service of the equipment. It was developed to assist electronic manufacturers to detect product defects during the design and production stages. This specialised equipment is widely used in various applications and can form part of the manufacturing process or it can be used in new product qualification testing.

ESS involves the testing of the impact of extreme temperature cycling (the products are exposed to a number of fast temperature changes which can range from – 30O  to 70+O C), vibration testing, shock and humidity variations.

Alaris believes that this implementation will advance customer service, since any defects uncovered during the Environmental Stress Screening process will lead to improvements in the manufacturing process.  In addition it will guarantee better operational reliability and performance of our products.

Impacting lives in the Alaris community

Mandela Day 2018 was celebrated at Alaris Antennas with the theme #ActionAgainstPoverty.

This annual international day in honour of Nelson Mandela, is celebrated annually on 18 July, Mandela’s birthday.  Mandela Day is a global call to action that celebrates the idea that each individual has the power to transform the world, the ability to make an impact.

At Alaris, we embrace the concept of “changing one life at a time” and this year, we decided to focus on a beneficiary in our local community.

There is so much need in and around our community for basic and essential items that we therefore decided to do a collection of non-perishable foods and sporting equipment for a high school close to our offices.

The school that was chosen as beneficiary, is Olievenhoutbosch Secondary School, based in the township of Olievenhoutbosch in Centurion, on the outskirts of Pretoria, South Africa.

A brief background to the school and justification to get involved:

  • This is a “no fee” and public school, based in the Olievenhoutbosch township in Pretoria.
  • The concept of a “no fee” school is that the parents do not pay school fees, since the school is located in a very poor community. They are dependent on grants from the Department of Education and the involvement of the business community.
  • The school has about 1400 learners and the 107 matriculants achieved a 100% matric pass rate last year, including a couple of distinctions.
  • The great concern is that some of the learners go without food for a whole day.
  • The school is managed by a strong and positive principal whose aim is to bring change to the community.

Alaris staff assisted in sorting and packing the collected goods, and a group of staff members visited the school to distribute the goods, which were gratefully received by the headmistress and representatives from the student body.

During this initiative, we were once again reminded that one individual can indeed make a difference in another person’s life:  In the words of Madiba:  “What counts in life is not the mere fact that we have lived. It is what difference we have made to the lives of others that will determine the significance of the life we lead.” 

Simplifying Direction Finding with the DF-A0047

The DF-A0047 is a handheld wideband direction-finding antenna, which has been used in multiple application areas. One of the more popular uses is ‘interference hunting’, whereby the antenna can be used to find a source of emitted interference by using received signal strength together with readings from the built-in electronic compass.

As an example consider a radio system consisting of a receiver and multiple transmitters.  Another transmitter in an unknown location is transmitting signals that are interfering with, and blocking signals from transmitters in the first system from being received.

In some instances, a source transmitter signal is identified by using an omnidirectional antenna, for example, on the roof of a vehicle, by driving around to find a circle inside which the interference source is transmitting from. This could typically be a large physical area.

The DF-A0047 is then used in the identified area to find the source of the interfering signal on the ground. The handheld antenna is pointed towards where the highest signal strength is found in one location. This is then repeated in one or two more locations. The results are then triangulated to find where the signal source is originating.

The antenna combines several antennas in a neat and compact housing, providing an all-in-one direction finding system covering a very wide frequency band as an alternative to using multiple antennas to perform the same function.

Alaris Antennas Patented Loop and Adcock Array Technology

Technology is an ever-changing field. For this reason, Alaris Antennas is constantly improving existing technologies as well as coming up with new ideas which complement and/or provide better performance than the older methods.

One of our patented technologies is our Hybrid Loop/Adcock Technology, which provides improved Radio Direction Finding performance.

The technology was developed as a result of the constant efforts to reduce the size of antennas while sacrificing little or no performance, often driven by the particular requirements for tactical applications. This technology provides the desirable qualities of Adcock arrays at high frequencies whilst substantially improving the low frequency sensitivity of electrically small Adcock arrays.

This method overcomes to a large extent the shortcomings that loops have when used in a DF array as the approach significantly reduces the sensitivity of the loop to undesirable cross-polarised signals which allows the loop to be used in a wider range of applications to perform DF. The new topology also overcomes the pattern breakup observed in normal loop topologies when the antenna starts becoming large. This allows the new loop design to be used over a much wider frequency range and to start approaching conventional Adcock Array performance at higher frequencies.

The loop antenna technology is able to suppress cross-polarized gain typical of traditional loops and when used in an Adcock array provides enhanced sensitivity when the array size is electrically small.

Dominating a Niche – The CEO Magazine Article

Recently we were contacted by The CEO Magazine, who wanted to do an article on the CEO of Alaris.  This is an international magazine, with its headquarters based in Sydney, Australia and with regional offices in Stockholm, Singapore and the Philippines. The article was written by Daniel Herborn from The CEO Magazine.

Headquartered in the South African city of Centurion, Alaris Antennas produces radio frequency products,  including custom antenna equipment. The products are used in electronic warfare, defence, homeland security, communication and frequency spectrum monitoring, as well as other specialised market sectors.

Juergen Dresel has been CEO of the company since 2015, but his involvement in the sector began much earlier. After completing studies in IT and
telecommunications as well as electrical engineering, Juergen worked in designing and developing antennas and antenna placement simulations.
“I was a co-founder of Poynting Antennas, so I’ve always been in a leading role,” Juergen says. “I was running the defence-market-related activities
of the company early on and built it up from when it was quite small, into something more significant.” Poynting Antennas later split into different divisions for commercial and defence antennas, with Juergen involved in the latter.

The defence division of Poynting Antennas later rebranded as Alaris Antennas to reflect its renewed focus as a B2B company. While there were previous efforts to diversify the company, Juergen says it has recently reaped the rewards of developing specialised expertise in defence and
communications antennas. “If you follow the larger industrial conglomerates, like General Electric and Siemens, they are starting to splinter off parts of the company and get back to their core areas. My view is that it is better to stay focused on what you’re doing and build in that direction.”

The two companies in Alaris Holdings group are Alaris Antennas and COJOT, a company that originated in Finland and designs and manufactures antenna products for military and security markets, including antennas suitable for manpacks and mission critical vehicles. There are significant
synergies across the two companies, and the collective skill set of the sister companies has allowed Alaris to access new markets and present opportunities for cross-selling.

As Juergen tells it, the company’s unique selling point is its adherence to three strategic pillars: its expertise in the radio frequency technology space; the global reach of its products; and its capacity to develop and exploit its intellectual property.

While many local competitors are concerned purely with importing and distributing radio frequency technology, Alaris Holdings has invested heavily in research and development to create its own proprietary technology. “That’s something we’re quite proud of,” Juergen says. “Having your own intellectual property gives you more independence, it allows you to control your destiny.” The company’s decision to concentrate on its own  technology also saw it sell off Aucom, a value-added reseller, as it was no longer a strategic fit.

The next major trend in antenna technology is smart antennas, which Juergen defines as equipment that includes an electronic component that allows for functions such as automatic frequency tuning, beam forming, beam switching and beam steering. “We are definitely positioning
ourselves to follow this requirement,” he confirms. The company is continuously innovating towards smaller, lighter antennas capable of operating with wider bandwidths and higher frequencies.

Alaris has embraced vertical integration by insourcing some time-sensitive services such as spray painting. Partnerships with reliable parts suppliers remain a key element of the business model. “There are a couple of suppliers in sub-Saharan Africa that we have close relationships with,” Juergen says.

The company also works closely with its partners to source difficult-to-find parts such as connectors, cables and other specialised components. “There is a little bit of everything – we source components from across Europe, the United States, sometimes Asia, but we have developed close relationships with certain suppliers.”

A particular field of expertise Alaris offers is its ability to design and manufacture tailor-made and boutique solutions for the specific needs of its customer base. “We position ourselves as a client-centric organisation,” Juergen says. “We typically win business by helping our clients with unique, innovative, bespoke solutions.”

Juergen says Alaris has built up electrical and mechanical engineering expertise to make such tailored products possible. It has know-how in CAD modelling, prototyping and simulation-based design, allowing the client to find the optimal antenna configuration for their needs. Antennas are
also thoroughly tested to ensure they can withstand environmental conditions such as salt spray, vibrations, extreme temperatures and exposure to water.

In a field where technical expertise is all-important, Juergen says attention to detail is one of his strengths as a leader. “I’m a firm believer in details,” he explains. “The view I take is that the more people within the business know and the more detail they have at their disposal, the better our business will be. The strategic path forward can be more clearly defined when you have more detail to work with.”

The company also works with an eye to the commercial needs of its clients. “We operate as competent, trusted advisers,” he explains. “This often helps the client to win business themselves. So, we have a fairly unique kind of position in the market and a unique product offering.”

Coming off strong performance in the last financial year, Alaris is exploring the possibility of offices in the US, Europe, and, later, Asia. The business is already overwhelmingly export-based, with 95 per cent of revenue coming from sales outside South Africa.

Juergen acknowledges there will be significant challenges moving into the US market, where acquisitions will be more expensive and the company will have to come to terms with a very different regulatory framework.

Alaris is committed to being a global concern, however, and is cognisant of the payoffs that come with gaining a foothold in what is by far the world’s largest market for defence and communication antennas. There are also tangible benefits, Juergen says. “Being client-centric, we need to be in close vicinity to our clients. The more often we can have face-to-face discussions with them, the better it is for us.”

A third operating company, based in the United States, is currently being added to the group to provide passive RF and microwave antenna solutions which complement the existing Alaris IP and extensive product range. “We have sold into the United States for years, but there is now enormous potential to grow sales in that market significantly. We definitely see ourselves as client-centric, which makes it important that we are geographically as close as possible to our customers in key markets like the US,” says Alaris Holdings CEO, Juergen Dresel.

Alaris presented its product line-up at the Electronic Warfare Europe 2018 exhibition and conference held in Lausanne, Switzerland on 5-7 June 2018. “This is an important networking opportunity for us. We are emphasising our unique IP and our highly skilled engineering team’s abilities to develop, design and manufacture specialised and customised sub-systems to rapidly meet individual client requirements,” Dresel notes.

Using the diverse core competencies in R+D, engineering and manufacturing possessed by its operating companies, Alaris provides electronic warfare and communications products for a variety of applications. These include electronic counter-measures to prevent the remote detonation of bombs, jamming of enemy communications, monitoring of enemy communications and signal direction finding. The products may be mounted on vehicles, aircraft, drones, ships and submarines, or carried by individual soldiers.

In the civilian environment, the company’s technology is used by test and measurement businesses and frequency regulatory bodies.

Among Alaris’ unique technical differentiators are wideband products which reduce the need for multiple antennas, the development of high-technology antenna arrays, and smart antennas that can be re-programmed to take on a variety of tasks.
