Omni-directional network antenna QuWireless QuSpot A140S-A, PoE/LAN, 0.694–2.7 GHz, up to 4 dBi, white

QuWireless QuSpot A140S-A is an omni-directional multi-band network antenna designed for cellular and wireless applications across 0.694–0.96, 1.7–2.2 and 2.2–2.7 GHz frequency ranges. The antenna provides up to 4 dBi gain (typical 2 / 4 dBi), vertical polarization and a compact white enclosure measuring 160 × 160 × 240 mm. It includes a PoE/LAN connector for integrated installations and can house a Teltonika TRB140 router to form an all-in-one outdoor or indoor solution for improving signal reception and distribution.

Advantages

The QuSpot A140S-A offers multi-band coverage in a single omni-directional unit, minimizing the need for multiple separate antennas. Its integrated PoE/LAN connector simplifies power-over-Ethernet installations and reduces cabling complexity. The compact, weather-resistant enclosure and the option to install a Teltonika TRB140 router inside deliver a unified, space-saving solution for deployments where a combined antenna and router is preferred. The white housing and moderate weight (1.5 kg) make it suitable for a wide range of mounting locations.

Suitable for

• Outdoor and indoor cellular signal enhancement for mobile and fixed installations
• Integrated deployments with Teltonika TRB140 router (all-in-one solution)
• Industrial sites, CCTV systems, public hotspots and remote monitoring
• Marine and recreational vehicles: yachts, boats, campers and RVs
• Small base stations and temporary installations requiring omni coverage

How to use

Mount the QuSpot A140S-A antenna in a position with clear exposure to the surrounding cellular towers and secure it using appropriate brackets or mast hardware. Connect the PoE/LAN connector to a compatible PoE injector or switch to deliver both power and data over a single cable. If installing a Teltonika TRB140 router inside the enclosure, follow the router manufacturer’s installation instructions to secure and configure the device before sealing the enclosure. Ensure cable entries and seals are properly tightened for outdoor use and verify antenna orientation for vertical polarization.

Recommendations

For optimal performance, place the antenna at the highest practical mounting point with minimal obstructions, and verify network band compatibility with your operator. Use shielded, outdoor-rated Ethernet cabling for PoE runs and perform signal testing after installation to confirm expected improvement in reception and throughput.
