2J Antennas

A Worldwide Manufacturer With Three RF Development Sites

2J Antennas is a Slovakia-headquartered antenna manufacturer founded in 2002 and headquartered in Bardejov, with global RF development sites in Slovakia, the UK, and the USA. The company designs, manufactures, and tests antennas in-house from concept through to certified product, supplying customers across automotive, marine, telematics, automation, and M2M markets in over 50 countries.

In 2023, 2J was acquired by discoverIE Group plc (LSE: DSCV), the Surrey-based international electronics group, for €52.5m. As part of discoverIE’s Sensing and Connectivity division, 2J was united with Antenova in February 2024 under a new leadership team led by CEO Keith Cornell. The two brands continue to operate independently with retained brand identities, sharing testing facilities and infrastructure across Slovakia, the UK, the USA, and (with Antenova) Taiwan. The combined cluster covers external and combination antennas (2J specialism) and internal antennas and RF modules (Antenova specialism), giving designers access to a broader product range from a single technology partner.

Millbeck supplies the 2J range across the UK, with stock of widely deployed products and access to the wider 2J catalogue through sourced-to-order delivery. Our Leeds-based technical team provides pre-sales advice on antenna selection, customisation specification, and integration with the wider Millbeck connectivity stack.

In short: 2J Antennas is a worldwide antenna manufacturer headquartered in Bardejov, Slovakia, with RF development sites in Slovakia, the UK, and the USA. Founded in 2002 and acquired by discoverIE Group plc in 2023, 2J was united with Antenova under discoverIE’s Sensing and Connectivity division in February 2024. The 2J portfolio covers 5G NR, 4G LTE, NB-IoT, LTE-M, Wi-Fi 6E, GNSS, and LPWA bands across internal patches, external pucks, magnetic and adhesive mounts, embedded FPC, and combination antennas with up to nine technologies in a single housing. Production holds RoHS, REACH, IATF 16949:2016, ISO 9001:2015, and ISO 14001:2015 certifications. Selected antennas carry IP67, IP69K, and IK09 ratings. Millbeck stocks widely deployed 2J products in the UK and supports custom variant specification through 2J’s engineering teams.

In-House Engineering and Pre-Certification Testing

What distinguishes 2J Antennas in industrial RF supply is the depth of in-house engineering capability across the design, prototyping, testing, and certification process.

Satimo CTIA-certified anechoic chambers at each of the three RF development sites (Slovakia, UK, USA) enable full pre-certification RF testing up to 60 GHz. Active and passive over-the-air (OTA) measurements include peak gain, total radiated power (TRP), total isotropic sensitivity (TIS), effective isotropic radiated power (EIRP), efficiency, and 2D and 3D radiation patterns. This means 2J can certify antenna performance at the design stage, before products go into production manufacturing.

3D printing and rapid prototyping allow new antenna housing designs to move from concept to physical prototype in significantly less time than traditional tooling-based manufacturing. For projects requiring custom mechanical form factors, this shortens the design iteration cycle and reduces the time to a working prototype.

End-to-end manufacturing brings plastic injection moulding, SMD pick-and-place assembly, automated cable assembly, ultrasonic welding, and quality control under one roof in Slovakia. This vertical integration supports tight control over product quality and shorter lead times for custom variants.

Pre-certification consulting at the USA site (Phoenix area) supports customers preparing for FCC, PTCRB, and other certifications before product launch. This is particularly valuable for OEMs whose product certification depends on antenna performance characteristics being validated upfront.

For UK customers, this engineering capability translates to faster custom variant turnaround, defensible certification documentation for the antenna portion of regulatory submissions, and the ability to specify products against specific RF performance criteria rather than just catalogue characteristics.

The 2J Product Range

The 2J catalogue spans the major form factors and frequency requirements UK industrial deployments encounter.

Internal antennas include surface-mount ceramic chip antennas, flexible printed circuit (FPC) antennas, and rigid PCB antennas designed for direct integration into customer products. These suit OEM applications where the antenna must sit inside the product enclosure, with electrical connection via U.FL, MHF4, or surface-mount feed points.

External single-band antennas include puck, screw-mount, magnetic mount, and adhesive form factors for cellular (4G LTE, 5G NR), Wi-Fi, GNSS, Bluetooth, and ISM bands as separate single-purpose products.

Combination antennas integrate multiple radio technologies into a single housing, supporting 5G, 4G LTE, Wi-Fi, and GNSS in unified products. The latest combination range includes products housing up to nine separate antenna technologies in a single enclosure, simplifying installations that would otherwise require multiple separate antenna mountings.

Specialist frequency antennas cover the niches that broadband antennas miss: 433MHz, 868MHz, and 915MHz LPWA bands for LoRa, Sigfox, and similar wide-area sensor networks; TETRA/UHF for legacy radio infrastructure; and Iridium for satellite IoT applications.

Development kits provide pre-tuned testing environments for OEMs evaluating antenna integration during product development, helping engineering teams verify performance and frequency characteristics before committing to production designs.

Cabling and connectors complete the antenna system: high-quality coaxial cable assemblies, U.FL and SMA connectors, splitters, and mounting hardware that converts standard antenna mounts into wall, pole, or magnetic configurations.

Mounting Options and Mechanical Form Factors

Industrial deployments rarely have an ideal mounting location available. 2J offers a wide range of mounting options designed to work around the physical constraints of real installations.

Magnetic mounts suit temporary or relocatable installations on metal surfaces, particularly fleet vehicle deployments where the antenna may need to be transferred between vehicles or removed for servicing.

Adhesive mounts provide low-profile attachment to plastic, glass, or composite surfaces where drilling mounting holes isn’t possible or desirable. Ideal for vehicle interiors, glass-fronted equipment cabinets, and aesthetic-sensitive installations.

Screw mounts provide permanent installation with mechanical security suitable for outdoor and industrial environments where vibration or attempted removal would compromise an adhesive or magnetic mount.

Surface-mount and embedded form factors integrate the antenna directly into the product PCB or product enclosure, suiting OEM applications where the antenna is invisible to the end user.

Flexible FPC designs allow antenna placement around irregular surfaces, inside curved enclosures, or in space-constrained product designs where rigid antenna form factors would not fit.

Marine and outdoor variants carry IP67 (dust-tight, temporary immersion protection) and IP69K (high-pressure, high-temperature water jet protection per ISO 20653) ratings for demanding environmental conditions. Selected ruggedised variants additionally carry IK09 mechanical impact resistance ratings (10 joules of impact energy) suitable for fleet vehicle, public safety, and industrial deployments where mechanical damage risk is significant.

Custom enclosure colours and labelling are available for OEM customers whose product branding or visual integration requirements need to extend through to the antenna.

Industrial Certifications and Quality Standards

For procurement and engineering teams, the 2J certification stack supports defensible supply chain compliance and product quality documentation.

RoHS (Restriction of Hazardous Substances) compliance ensures 2J products meet EU restrictions on hazardous materials, supporting product compliance for EU and UK markets.

REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) compliance addresses the EU regulation on chemical safety, supporting customer compliance for products marketed in the EU and UK.

IATF 16949:2016 certification (the automotive industry’s quality management standard) supports use in automotive applications including OEM supply chains for vehicle manufacturers, telematics products, and connected vehicle infrastructure.

ISO 9001:2015 certifies the quality management system covering 2J’s design, manufacturing, and customer service processes.

ISO 14001:2015 certifies environmental management for 2J’s manufacturing operations.

CE marking is supported across the 2J range for EU and UK regulatory compliance.

For applications in defence and aerospace, 2J’s NATO-based manufacturing status and CTIA-certified pre-certification testing support regulatory submission processes.

For procurement teams sourcing antennas for industrial applications, this certification stack is among the strongest in the antenna market, particularly relevant for automotive supply chains where IATF 16949 is typically a procurement requirement.

Optimised for 5G NR, Wi-Fi 6E, and IoT Technologies

Industrial wireless is moving rapidly across multiple radio technologies, and the 2J portfolio is engineered to support the current and forward-looking frequency requirements UK deployments encounter.

5G NR (sub-6GHz New Radio) coverage spans the bands UK operators are deploying, including the 700MHz band for coverage applications, the 3.4-3.6GHz mid-band for capacity deployments, and forward-compatible coverage for the 26GHz millimetre-wave allocation where it sees deployment in venues and high-density applications.

4G LTE coverage includes Cat 4 through Cat 18 bands, supporting current LTE deployments and the LTE backwards compatibility that 5G NR networks rely on for fallback.

LTE-M (Cat-M1) and NB-IoT (Cat NB1, NB2) coverage suits low-power IoT applications including smart metering, asset tracking, and remote monitoring where extended battery life and deep-penetration coverage matter more than throughput.

Wi-Fi 6E coverage extends through 2.4GHz, 5GHz, and the 6GHz band, with selected 2J products forward-compatible with Wi-Fi 7 (802.11be) deployments.

GNSS multi-constellation coverage supports L1, L2, and L5 bands across GPS, Galileo, GLONASS, and BeiDou constellations, suiting applications requiring high-precision positioning, multi-constellation redundancy, or signal quality in challenging environments.

LPWA bands (433MHz, 868MHz, 915MHz) cover LoRa, Sigfox, and similar low-power wide-area sensor networks for smart agriculture, smart cities, environmental monitoring, and industrial sensor deployments.

Specialist bands including TETRA/UHF and Iridium cover legacy public safety radio infrastructure and satellite IoT applications respectively.

This wide-band coverage matters for long-life infrastructure deployments because antenna replacement in the field is operationally expensive. Specifying broadband-capable antennas at deployment is significantly cheaper than retrofitting later when operators repurpose spectrum or add new bands.

Combining 2J Antennas With the Connectivity Stack

Antennas only deliver their performance when matched to the rest of the connectivity stack: router, SIM, cabling, mounting, and the physical environment.

Millbeck supplies 2J antennas alongside the rest of the connectivity stack: industrial routers and gateways from across the hardware portfolio, Millbeck IoT SIMs (UK roaming for multi-carrier resilience, global roaming for international deployments, eSIM or eUICC for long-life applications, NB-IoT and LTE-M profiles for low-power deployments), and the cabling, connectors, and mounting hardware that complete the installation. We confirm antenna and router connector compatibility, cable specifications, and grounding requirements at the design stage, and pre-test compatibility for high-stakes deployments.

For OEMs at scale, we coordinate with 2J’s engineering teams to specify custom variants, manage production orders against framework agreements, and consolidate the BOM across antennas, cabling, routers, and SIMs into a single supply chain relationship.

UK Stock and Custom Variant Specification

Millbeck holds UK stock of widely deployed 2J antennas and accesses the wider 2J catalogue through sourced-to-order delivery from the Slovakia manufacturing site. UK stock typically ships next-day for prototype orders, with volume pricing and supply chain agreements available for OEM and integrator customers building production deployments.

For custom variant specification (cable lengths, connector types, enclosure colours, frequency tuning), Millbeck coordinates with 2J’s UK and Slovakia engineering teams to specify the variant, agree on lead times, and manage production orders against the customer’s deployment timeline. This route is significantly faster than a fully custom antenna design, while still delivering an antenna tailored to the specific deployment requirement.

For pre-certification testing, Millbeck can coordinate access to 2J’s Satimo anechoic chambers for customers needing to verify antenna performance against regulatory submission requirements before committing to production volumes.
