Omni-directional network antenna Poynting A-MIMO-0003-V2-17-B, 0.41–3.8 GHz, 21 dBi, SMA male

Poynting A-MIMO-0003-V2-17-B is an omni-directional, wideband network antenna designed for multi-technology installations. The unit integrates multiple radiating elements in a single compact housing to deliver cellular, Wi‑Fi and GNSS reception across 0.41–3.8 GHz with a maximum gain of 21 dBi and 50 Ω impedance. Its SMA male connector and robust physical design make it suitable for vehicles, marine vessels and fixed-site IoT or broadband applications where reliable, multi-band reception and MIMO capability are required.

Advantages

The antenna provides seven high-performance radiating elements in one enclosure: four cellular MIMO elements, two dual-band Wi‑Fi elements and an active GPS/GLONASS element. Ultra-wideband coverage includes legacy cellular bands and emerging LTE/5G bands (including 450 MHz and the 3.5 GHz CBRS region), enabling compatibility with multiple operators and future network upgrades. The antenna is engineered for omnidirectional coverage with balanced radiation patterns and pattern diversity, improving link reliability in mobile and marine environments. Its compact footprint and durable build allow flexible mounting and long-term outdoor use.

Suitable for

• Commercial and industrial vehicles requiring reliable cellular data and GPS/GLONASS positioning
• Marine vessels and offshore platforms needing omnidirectional multi-band coverage
• M2M and IoT gateways that use multiple radio technologies and MIMO setups
• Fixed broadband installations where wideband reception and futureproofing for 5G are important

How to use

Mount the antenna on an appropriate external surface or mast using the recommended hardware and ensure the housing has a clear, unobstructed view for omnidirectional coverage. Connect the SMA male connector(s) to the corresponding radio modem, router or access point inputs, and supply the required 2.7–3.3 V to the active GNSS element if required by the installation. Positioning the antenna centrally on the vehicle or vessel roof improves pattern coverage and MIMO diversity. Verify cable routing and connector seals to maintain environmental protection and minimize signal loss.

Recommendations

For best performance, place the antenna as high as practical with minimal metallic obstruction nearby. Use low-loss coaxial cable and properly torque SMA connections to reduce insertion loss. When deploying in marine or high-vibration environments, check mounting hardware regularly and follow manufacturer guidance for grounding and lightning protection.
