Mobile Mark LTM2900 Series 5G Multiband Surface Mount Antenna

LTM2900 Series 5G Antenna Datasheet

The Mobile Mark LTM2900 Series is a configurable multiband surface-mount mobile antenna platform designed to support combinations of Cellular, WiFi 6E/7, and GNSS radios in a single rugged housing. Its compact radome enclosure is optimized for mobile installations where space, performance, and durability are critical.

Built for modern fleet and vehicle connectivity systems, the MobileMark LTM2900 Series can support configurations of up to four 5G Sub-6 cellular elements, up to six WiFi 6E/7 elements, and one GNSS element. It can also be configured with fewer WiFi elements as needed, giving integrators the flexibility to match specific network and application requirements.

The rugged antenna housing features an ASA UV-inhibitive plastic radome with a corrosion-resistant aluminum base, making it well suited for demanding outdoor and mobile environments. When properly mounted, the antenna offers IP69K-rated dust and water ingress protection and meets a range of shock and vibration standards for transportation and fleet use.

With wideband support across 617–960 MHz, 1710–7200 MHz, 2.4–2.5 GHz, 4.9–7.2 GHz, and GNSS frequencies including 1561, 1575, and 1602 MHz, the LTM2900 Series delivers versatile multi-radio performance for connected vehicles, public safety, transit, and other mission-critical mobile applications.
