MikroTik LHGGR&FG621-EA LTE Cat6 Sector Antenna 2x2 MIMO IP54

The MikroTik LHGGR&FG621-EA is an outdoor LTE Cat6 CPE kit that pairs a high-gain directional antenna with an integrated LTE modem and Gigabit Ethernet interface, purpose-built for fixed wireless access deployments where maximizing cellular throughput to the premises is the priority. The upgrade from Cat4 to Cat6 raises the downlink ceiling to 300 Mbps and the uplink to 50 Mbps, while the addition of Gigabit Ethernet ensures the backhaul port is no longer the bottleneck between the modem and the customer network. The antenna covers LTE FDD bands spanning 700 MHz through 2600 MHz as well as three LTE TDD bands and four 3G bands, giving the unit genuinely broad carrier compatibility across North America, Europe, and beyond. Running RouterOS v7 on a dual-core 64-bit ARM processor with 256 MB of RAM, the device supports the full MikroTik software feature set for routing, firewalling, and traffic management at the edge. The IP54-rated weatherproof enclosure with passive cooling has been validated across a tested ambient range of -40 °C to 70 °C, making it suitable for rooftop and tower-top installations in demanding climates without requiring active thermal management or frequent on-site maintenance.

Key features & benefits

• LTE Category 6 Modem — The integrated Cat6 modem delivers up to 300 Mbps downlink and 50 Mbps uplink, a meaningful step beyond Cat4 predecessors that removes the modem as a throughput constraint for bandwidth-intensive fixed wireless applications.
• Gigabit Ethernet Backhaul — A single 10/100/1000 Mbps Ethernet port ensures the connection between the outdoor unit and the indoor network can fully carry the LTE modem's potential throughput without the 100 Mbps ceiling of earlier LHG generations.
• Wide Multi-Band LTE Coverage — Support for LTE FDD bands 1, 3, 5, 7, 8, 20, and 28 plus LTE TDD bands 38, 40, and 41 spans 700 MHz to 2600 MHz, enabling deployment on a broad range of carriers and regulatory environments worldwide.
• 802.3af/at PoE Input — The unit accepts 12–57 V Power over Ethernet compliant with 802.3af/at standards, allowing a single Cat5e or Cat6 cable to carry both data and power to the rooftop mount and keeping installation tidy and cost-effective.
• IP54-Rated Weatherproof Enclosure — The IP54 ingress protection rating combined with a tested operating range of -40 °C to 70 °C and passive cooling means the unit is designed to survive harsh wind, rain, and temperature extremes without active components that could degrade over time.
• Dual-Core ARM 64-bit RouterOS v7 Platform — The 88F3720 dual-core CPU running at 800 MHz with 256 MB RAM and 16 MB Flash storage runs RouterOS v7 under license level 3, giving network administrators access to MikroTik's routing, NAT, firewall, and traffic-shaping feature set directly on the CPE.
• 2x2 MIMO Downlink Antenna — The integrated high-gain antenna supports 2x2 MIMO on the downlink, allowing the modem to exploit spatial multiplexing for higher aggregate throughput and improved link reliability in real-world deployments.
• 3G Fallback Support — The modem includes 3G Category R8 capability across bands 1, 3, 5, and 8, providing automatic fallback connectivity in areas where LTE coverage is marginal or absent.
