MIMO directional antenna Lancom Systems AirLancer IN-H180 — 2.4–5.9 GHz, 5 dBi, RP-SMA, dual polarization

The LANCOM AirLancer IN-H180 is a MIMO directional ceiling antenna designed for indoor wireless networking across 2.4–5.9 GHz. With dual polarization and a maximum gain of 5 dBi, it supports IEEE 802.11ac environments and provides focused coverage when mounted under suspended ceilings or on walls. The compact housing (130 × 130 × 45 mm) and RP-SMA connectors make the antenna suitable for integration with access points where reliable point-to-point or point-to-multipoint links and improved link stability are required.

Advantages

The antenna combines a 180° radiation characteristic with MIMO capability, enabling improved coverage and link reliability in challenging indoor layouts. Dual polarization increases resilience against signal fading and orientation mismatch, while the low-profile design allows discreet installation beneath suspended ceilings or on flat surfaces. Included RG-178 cable and a mounting kit simplify installation and connection to compatible APs using RP-SMA interfaces.

Suitable for

• Enterprise environments such as offices, hospitals, and schools requiring discreet ceiling-mounted Wi‑Fi coverage
• Hotels and public buildings where unobtrusive installation is preferred
• Indoor point-to-point or point-to-multipoint links with directional coverage needs
• Deployments using dual-radio access points operating in parallel at 2.4 GHz and 5 GHz

How to use

Mount the antenna under a suspended ceiling or on a suitable flat surface close to the access point to achieve the intended directional coverage. Connect the RP-SMA connectors to the corresponding antenna ports on the access point using the supplied RG-178 cable or compatible cabling. Orient the antenna so that the 180° coverage faces the area requiring coverage, and verify dual-radio AP settings to enable parallel operation on 2.4 GHz and 5 GHz where applicable. After physical installation, perform site surveying and signal measurements to fine-tune placement and AP antenna port assignments for optimal performance.

Recommendations

Place the antenna centrally within the target coverage zone and keep the path to the access point free from large metallic obstructions. For multi-antenna systems, follow the access point manufacturer’s guidelines for antenna port mapping and cabling to ensure correct MIMO operation. Regularly verify antenna connections and cable integrity to maintain consistent performance.
