The heavy-duty, IP67 rated, external enclosure combines 5 antenna elements in a low profile, compact form. The Guardian combines 1x GNSS and 4x 5G/4G Cellular antennas making it compatible with the next generation of modules and routers. The MA945 has been designed as a low-profile solution for IoT and Automotive applications where space is at a premium allowing it to be installed in the headliners of vehicles or on the back window of a vehicle. The Guardian series is an ideal external combination antenna solution that can be used where drilling a hole through the roof of a vehicle or a metal panel for an external antenna is not feasible or desired. Typical applications include: - Passenger Bus and Rail Applications - Automotive and Heavy Equipment - Vehicle Tracking and Telematics - First Responder and Emergency Services - HPUE applications such as Public Safety Communications and Critical Infrastructure and Utilities The Guardian can be adhesive, or wall mounted as standard. The adhesive pad and wall bracket are included in the product packaging. Pole and desk mount option are also available as separate kits. Taoglas also provides services to ensure optimum overall performance for your entire system by working closely with the customer to design in the best antenna and potential additional components for your system. 5G/4G applications demand high-speed data uplink and downlink. High efficiency and high gain MIMO antennas are necessary to achieve the required signal to noise ratio and throughput required to solve these challenges. 3 www.taoglas.com SPE-24-8-158-A Taoglas also takes care to ensure high isolation between the MIMO antennas to prevent self-interference. Low loss cables are used to keep efficiency high over longer cable lengths. In contrast, smaller MIMO antennas with poor quality thin cables will have reduced efficiency and isolation, which would lead to a large drop in system throughput, increased incidences of signal drops, and may indeed not make a system connection at all. Cable type and length, and connectors are fully customizable, and the Guardian can also be customized for other configurations.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
