Taoglas Expands Comet Antenna Series with Compact Screw-Mount Solutions Engineered for Metal Enclosures
San Diego, CA, 23 September 2025 – Taoglas®, a trusted provider of advanced RF and antenna solutions, today announced the expansion of 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 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 just 101 x 101mm and super low profile of just 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 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.
“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 available now 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 ideally 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 recent Taoglas white paper here.
