Taoglas expands comet antenna series with models engineered for metal enclosures

Taoglas has expanded its Comet Series with the MA58x family of compact, discrete, screw- or through-hole mount puck antennas.

Metal structures or flat surfaces, such as cabinets, can affect antenna performance and change the electrical groundplane. The Comet MA58x 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, turning it into an unintended radiator. The MA58x design removes this dependency, enabling efficient radiation and delivering at least 20% better performance than comparable alternatives.

With a footprint of 101 x 101 mm and low profile of 20 mm, the antennas deliver reliable multi-antenna connectivity across GNSS constellations including GPS, GLONASS, Galileo, and BeiDou, as well as 5G/4G MIMO and Wi-Fi 6/7. Advanced RF design enables consistent gain and efficiency across global cellular frequencies from 600 MHz to 6 GHz and Wi-Fi bands up to 7.125 GHz, while also supporting legacy 2.4/5.8 GHz 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 molded in Acrylonitrile Styrene Acrylate (ASA) for long-term outdoor durability, and the IP67-rated enclosure with a screw/stud mount provides a permanent installation option that ensures secure, reliable operation in vibration-prone and harsh conditions such as fleet vehicles, heavy equipment, and industrial automation.

The new antennas are available in multiple configurations and 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 suited to 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 address different deployment needs.

Further details on the design principles that deliver these performance gains are available in a Taoglas white paper.
