Directional antenna Lancom Systems AirLancer ON-D8a — 21 dBi, 4.9–5.9 GHz, N-type, dual linear polarization

The Lancom Systems AirLancer ON-D8a is an outdoor directional Wi‑Fi antenna designed for focused long‑range wireless links in the 4.9–5.9 GHz band. With a maximum gain of 21 dBi, an 8° beam angle and dual linear polarization, the antenna supports directed point‑to‑point connections and improves signal stability for 2x2 MIMO radio systems. Housed in a compact weatherproof metal enclosure (370 × 370 × 30 mm) and fitted with an N‑type connector and 50 Ω impedance, this antenna is suitable for mounting on walls or masts and is compatible with common outdoor access points that support directional links.

Advantages

The AirLancer ON‑D8a combines high gain and a narrow beam to concentrate RF energy toward the intended receiver, reducing interference and signal spill to adjacent areas. Dual linear polarization supports MIMO operation for improved throughput and link reliability. The included mounting kit, adapter and cables simplify installation on poles or building facades, while the weatherproof metal housing ensures durability in outdoor environments.

Suitable for

• Long‑distance point‑to‑point Wi‑Fi links between buildings or sites
• Sectorized outdoor coverage where focused signal is required
• Use with 2x2 MIMO outdoor access points to increase link throughput and stability
• Environments that require weatherproof, pole or wall‑mounted directional antennas

How to use

Mount the directional antenna on a stable pole or wall bracket using the supplied mounting kit and align it precisely toward the remote antenna or coverage area to achieve optimal link performance. Connect coaxial feed cables with N‑type connectors to the antenna ports and route them to the outdoor access point or radio. Configure the wireless devices for 2x2 MIMO operation and set appropriate channel, power and security parameters. Verify alignment and link quality with RSSI and throughput tests, then secure all cable connections and weather‑seal exposed joints.

Usage recommendations

For reliable long‑range links, pair the AirLancer ON‑D8a with an outdoor access point that supports 2x2 MIMO and use professional alignment tools to minimize misalignment. Maintain clear line‑of‑sight between endpoints and avoid mounting locations near large metal obstacles. Use high‑quality low‑loss coaxial cable and properly sealed N‑type connectors to preserve signal integrity in outdoor installations.
