Omni-directional network antenna QuWireless A140I, 0.7–2.7 GHz, 2/3 dBi, PoE/LAN connector

QuWireless A140I is an omni-directional network antenna designed for broad multiband coverage across 0.7–2.7 GHz. With a nominal gain of 2/3 dBi and a maximum of up to 3 dBi, the antenna uses vertical polarization to provide consistent reception in all horizontal directions. The compact enclosure (165×165×54 mm) integrates a PoE/LAN connector for combined power and network connection and includes space to mount a Teltonika TRB140 router, creating an all-in-one platform for mobile and fixed installations.

Advantages

The antenna’s omni-directional pattern simplifies installation when the desired signal direction is unknown or varies over time, reducing the need for precise alignment. Its multi-band frequency support covers a wide range of LTE and cellular bands within 0.7–2.7 GHz, enabling compatibility with diverse network providers. The integrated PoE/LAN connector allows single-cable deployment for power and data, while the compact, weather-sheltered enclosure supports placement in indoor or protected outdoor locations. The dedicated space for the Teltonika TRB140 router offers a tidy, combined solution that minimizes cabling and cabinet requirements.

Suitable for

• Expanding wireless coverage for routers and gateways in homes, offices, and small commercial sites
• Mobile and fixed installations such as yachts, boats, campers and RVs
• Industrial and CCTV connectivity where compact multi-band reception is required
• Public hotspots and temporary sites that benefit from quick, single-cable deployment

How to use

Mount the QuWireless A140I in a sheltered indoor or protected outdoor location with clear exposure to the surrounding area to take advantage of its omni-directional coverage. Install the Teltonika TRB140 router into the provided compartment if using the all-in-one option, connect the router to the PoE/LAN connector and run a single Ethernet cable to a PoE injector or switch to provide both data and power. Ensure the antenna enclosure is fastened securely and oriented upright to preserve vertical polarization. After connection, verify signal strength and network registration on the router and adjust placement within the sheltered area if necessary.

Recommendations

Place the antenna where it has minimal obstruction from large metal surfaces and maintain an upright orientation to preserve vertical polarization. Use a PoE injector or PoE-enabled switch rated for the router’s power requirements and follow local regulations for outdoor mounting. For best results in weak-signal locations, test several sheltered mounting positions and verify carrier band compatibility within 0.7–2.7 GHz.
