At COJOT, we continuously explore ways of making our antennas superior and best in class to help our customers amplify their offer to the market.

Our world class whip antennas have been upgraded with a new and improved whip removal system.  We have replaced the old mounting screws with a thumb screw that allows the user to remove and re-attach the antenna whip without the aid of tools.

Our rugged, low profile, high-performance wide band vehicle antennas upgraded with this latest improvement are

• The WB20140M  which is a rugged low-profile wideband antenna for communication and jamming applications in the 20 – 140 MHz frequency range and is used on various vehicles types.
• The WB20CM is a low-profile wideband compact VHF antenna for vehicle based communication and jamming applications in the 20 – 140 MHz frequency range
• The C30512M is a rugged, low profile and high-performance vehicle antenna providing maximum performance for modern tactical radios.
• C30512M GPS is a VHF/UHF Vehicular C3I Antenna (with option for GPS)
• The WB3090M is a rugged, low profile vehicle antenna that is ideally suited for mobile C3i applications in the 30 – 110 MHz frequency range  and is also used on almost all vehicle types.
• The WB30512M is a rugged, high-performance VHF/UHF vehicle antenna for use in jamming and communications applications within the 20 – 520 MHz frequency range.
• The WB30512XM is a high-power VHF/UHF vehicleantenna that has been designed for Counter-RCIED and jamming applications within the 20 – 520 MHz frequency range.

 This change has been verified against the electrical and environment requirements of the original design and has proven to comply with all requirements.  Electrical performance is not affected by this change.

LAND FORCES 2021 is a premier international land defence exposition, showcasing equipment, technology and services for the armies of Australia and the Indo-Asia-Pacific.

Rojone, a partner to COJOT will be exhibiting at this year’s Land Forces exhibition.  They will showcase a range of cojot handheld antennas as well as our SBA4450B.

The SBA4450B is a switched beam antenna for the 4400 to 5000 MHz frequency band (UHF band IV). The antenna beam can be switched by remote control to achieve optimal gain to the desired direction and to avoid interference from unwanted directions. The antenna provides up to 20 sharp beams with a minimum of 20-degree beam width to cover the full 360-degree horizontal area. In addition to these sharp beams the antenna can also provide wider beams. The antenna provides superior gain performance with low side lobe levels. Its extremely fast beam switching ability makes the antenna suitable for complex node network in tactical communication.

South African based Alaris Holdings has long been on the lookout for opportunities to widen its already substantial footprint, which has resulted in the acquisition of UK based Linwave Technology. A specialist in the RF (radio frequency) technology field, Alaris Holdings company has grown from a small consulting service into a powerhouse, globally recognised for its extensive expertise and continuous development of intellectual property.

The Alaris Holdings Group currently consists of four entities – Alaris Antennas (based in South Africa), COJOT (based in Finland), and mWAVE Industries and Alaris USA (based in Maine, USA). With the acquisition, the Group increases its global footprint even further, boding well for future growth.

UK based Linwave Technology was founded in 2003 and focuses on the design and manufacture of  RF/microwave components and subsystems. The company supplies its advanced and customised products across multiple markets, from defence, avionics, marine, industrial, satcom and healthcare to space, wireless, transport and security. Their extensive RF/microwave capabilities were a great attraction for the Alaris Group, as was the prospect of widening its scope into other markets from its core in the defence segment.

Alaris Holdings Group CEO, Juergen Dresel, has indicated previously that Alaris set out to complement the Group with strong RF/microwave electronics design and RF assembly capabilities. Linwave Technology fits this strategic requirement like a glove. A share purchase agreement was signed on Friday 26 February, with the same effective date.

“Linwave will contribute greatly to the diversification of various elements in the Group, adding new products, new customers, new territories and new market segments like medical and aviation. There is no doubt that this will lead to some great cross-selling opportunities within the Group,” stated Juergen Dresel.

While Linwave already boasts an expert skillset in the RF/microwave field, Chris Carr, Linwave’s Sales Director, said that they are “excited to become part of an international group of companies, thereby exploiting synergies to create new business opportunities.” He added that “the acquisition will provide an opportunity to integrate our RF/microwave electronics technology with the core antenna business of Alaris, to produce cutting edge and advanced system solutions to our combined customer base.”

The acquisition is a watershed for both the Alaris Holdings Group and Linwave Technology. The Alaris Holdings subsidiaries have developed their product range over the years from a components-based offering to more complete antenna systems solutions. By adding a strong competency in RF/microwave electronics design and manufacture, which complement the product offering, the Group and its subsidiaries will be well-positioned to take a distinctive lead in a niche market. Moreover, it is expected that Alaris’s established global footprint will assist Linwave in its drive to fulfil export potential and support a wider customer base outside the UK.

The companies share very similar value systems – centred around the customer – providing dedicated engineering teams driven by an open, honest interest in supporting their customers’ needs and providing world class RF and microwave technologies for specialised requirements and harsh environments.

Ian Duke, Managing Director of Linwave Technology, noted that “the management team and shareholders of Linwave are excited about the future of the business” and confirmed that “Linwave is proud to be able to add value to the already advanced Alaris products by means of our intellectual property.”

Mr Dresel added that “the plan is that Linwave becomes the ‘go-to place’ for RF/microwave design and developments required within the Group”, concluding that “by Linwave becoming part of the ALH Group of companies, (it) will allow us to become more system orientated. This enables us to strategically move up vertically in the value chain.”

Following its normal approach, Alaris will make no changes to the Linwave management team. Linwave will join its sister companies, COJOT and mWAVE under the Alaris UK Investment holdings entity, and the Linwave board will remain majority manned by UK residents.

COJOT is part of the Alaris Holdings Group of Companies.

In striving for service excellence, COJOT continuously looks for new or improved ways of working with test measurement.  Recently, we introduced new software in our anechoic chamber to improve our measurement and testing procedures.

We are now able to measure the products through their operating bands about 60-70 times faster. In addition to the shorter test measurement time, the software enhances the capturing of antenna performance characteristics in greater detail that provides more information and speed for analysing the antenna designs.

Jarkko Unkeri, VP Product Management at COJOT stated that “in the long run, this improved efficiency shortens our time to market, giving our customers more time to work on other critical aspects of their projects.”
