Directional antenna Lancom Systems AirLancer ON-QT90 — 2.4–7.125 GHz, 6 dBi, N-type, dual linear polarization

The Lancom Systems AirLancer ON-QT90 is a directional outdoor sector antenna designed for focused wireless coverage across the 2.4–7.125 GHz range. With a nominal gain of 6 dBi and a 90° beam angle, this compact antenna (183.7 × 40 × 233.7 mm) supports tri-band operation across 2.4, 5 and 6 GHz and is intended for point-to-point or point-to-multipoint installations that require reliable, concentrated RF coverage. The antenna features an N-type connector and dual linear polarization to improve link stability and performance in environments with reflections and scattering.

Advantages

The ON-QT90 offers 4x4 MIMO support across all four ports to increase throughput and client capacity in demanding environments such as warehouses and factories. Its tri-band compatibility including the 6 GHz band provides future-proof operation and flexible deployment with mixed-frequency networks. Built for outdoor use, the antenna comes with a mounting kit for wall and pole installation and includes cable and adapter accessories for straightforward integration with LANCOM access points. Dual linear polarization enhances link robustness by reducing polarization mismatch effects.

Suitable for

• Outdoor sector coverage for warehouses, factory halls and large outdoor venues
• Point-to-multipoint deployments requiring a 90° horizontal beam
• Mixed 2.4 / 5 / 6 GHz networks and tri-band Wi‑Fi installations

How to use

Mount the antenna on a suitable wall or pole using the supplied mounting kit and align it to provide a 90° sector coverage area toward the client population or remote sites. Connect the RF cable to the N-type connector and use the provided adapter where necessary to interface with LANCOM indoor or outdoor access points. Position the antenna at an appropriate height and orientation to minimize obstructions and maximize line-of-sight paths; use multiple antennas or additional sectors for complete area coverage. Verify alignment and channel configuration in the controller or access point management software and test client connectivity and throughput after installation.

Usage recommendations

Install the antenna with clear sight lines where possible and maintain separation from other RF equipment to reduce interference. Use the 4x4 MIMO ports with compatible LANCOM access points to achieve better spatial diversity in reflective environments. When deploying in mixed band networks, plan channel allocation to avoid co-channel interference between 2.4, 5 and 6 GHz devices.
