MikroTik LHG XL 5 ax 27 dBi Wi-Fi 6 Outdoor PtP CPE

The MikroTik LHG XL 5 ax is the answer to the oldest problem in outdoor wireless networking: getting a fast, stable link across a distance that makes standard access points irrelevant. At 27 dBi, the LHG XL 5 ax generates the antenna gain needed to bridge buildings, connect remote sites, and share internet across infrastructure gaps where nothing else at this price point is viable.

The jump from the previous LHG generation to the LHG XL 5 ax is not a spec sheet refresh — it is a generational change in the wireless standard. Wi-Fi 6 (802.11ax) brings 1024-QAM modulation, OFDMA, and improved spectral efficiency to the LHG platform for the first time. In real-world outdoor links, this translates to higher throughput per MHz, more reliable data rates in noisy RF environments (adjacent channels, competing links, interference from other ISM-band devices), and lower latency under load. The previous generation ran 802.11ac at best; the LHG XL 5 ax runs 802.11ax.

WPA3 security is built-in — the current gold standard for wireless encryption, replacing WPA2 in deployments where security requirements have been updated. For managed ISP CPE deployments, WPA3 satisfies modern compliance requirements without additional configuration.

The aerodynamic grid antenna design is a deliberate engineering choice for permanent outdoor installations. Grid antennas shed wind load significantly better than solid dish antennas — critical for tower mounts, rooftop installations, and exposed pole mounts in Canadian weather conditions where wind and ice accumulation are real operational factors.

The Gigabit Ethernet port with passive PoE-in (12–28V) keeps the installation clean — a single cable carries both data and power from the included PoE injector to the unit, with no separate power supply run required at the mounting point. At 5W maximum power consumption, the LHG XL 5 ax is one of the most power-efficient 5 GHz outdoor units in its class.
