Antenna series features compact screw-mount solutions engineered for metal enclosures

Taoglas has expanded its Comet Series with the new MA58x family of compact, discrete, screw- or through-hole mount puck antennas. Metal structures or flat surfaces, such as cabinets, can impact antenna performance and alter the electrical ground plane. The new series is specifically engineered to maintain stable, high-efficiency operation in these challenging conditions.

Conventional LTE antennas rely on their RF cable to achieve low-band efficiency, particularly when the cable itself is routed inside a metal enclosure, making it an unintended radiator. The design removes this dependency, allowing efficient radiation and delivering at least 20% better performance than comparable alternatives.

With a footprint of just 101mm x 101mm and a super-low profile of only 20mm, the antennas deliver reliable multi-antenna connectivity across 5G/4G MIMO, Wi-Fi 6/7, and GNSS constellations, including GPS, GLONASS, Galileo, and BeiDou. Advanced RF design allows consistent gain and efficiency across global cellular frequencies from 600MHz to 6GHz and Wi-Fi bands up to 7.125GHz, while also supporting legacy 2.4/5.8GHz Wi-Fi and Bluetooth for maximum compatibility. These levels of performance are rarely achieved in antennas of this size, and even more so when installed on metallic structures.

The rugged, weather-resistant housing is moulded in ASA for long-term outdoor durability, and the IP67-rated enclosure with a screw/stud mount provides a permanent installation option that provides secure, reliable operation in vibration-prone and harsh conditions such as fleet vehicles, heavy equipment, and industrial automation.

“Metal housings are often unavoidable in real-world deployments, and they can present serious challenges for RF performance,” said Baha Badran, head of Engineering, Taoglas. “With the Comet MA58x Series, we’ve addressed that head-on, while also delivering the efficiency, reliability, and multi-antenna performance that are normally very difficult to achieve in such a compact form factor. This combination gives our customers confidence that their systems will stay connected, whatever the environment.”

The new antennas are now available in multiple configurations and supplied in either black or white enclosures. Custom cable lengths and connector options are also offered, making integration more flexible for OEMs and system designers. The MA58x Series is ideal for gateways and routers, public safety systems, point-of-sale terminals, digital signage, smart home automation, robotics, and industrial automation. The Comet Series also offers a magnetic mount MA32x variant to handle different deployment needs.
