Outdoor cellular signal booster Mikrotik LHG LTE18 kit

The Mikrotik LHG LTE18 kit is an outdoor cellular signal booster designed to provide reliable mobile internet in remote and rural locations. Equipped with a Cat18 LTE modem and a high-gain 17 dBi grid antenna, the kit supports speeds up to 1 Gbps and improved reception where conventional signals are weak or unavailable. The unit includes a Gigabit Ethernet port with PoE-in, a MicroSIM slot and a robust heat sink in a weather-resistant grid design suitable for pole or mast mounting.

Advantages

The LHG LTE18 kit combines a 1.2 Gbps Cat18 modem with carrier aggregation to use multiple frequency bands simultaneously, improving throughput in crowded or weak-signal environments. Its large 17 dBi antenna and support up to 2.7 GHz extend coverage and enable connections to distant cell towers. The device features a durable grid antenna and substantial heat dissipation for stable operation outdoors, plus a Gigabit Ethernet port with PoE-in and included power injector for flexible powering options.

Suitable for

• Providing last-mile internet in rural and remote areas
• Improving mobile broadband where signal strength is low
• Outdoor installations on poles or masts for homes, cabins or small sites
• Situations requiring carrier aggregation to increase throughput

How to use

Mount the LHG LTE18 kit on a pole or mast in a location with clear line of sight toward the nearest cell tower to maximise signal reception. Connect a MicroSIM card in the SIM slot and power the device via the Gigabit Ethernet PoE input using the included injector or a compatible PoE source (12–57 V). Configure network settings through the device’s management interface and monitor signal strength to fine-tune antenna orientation for optimal speeds.

Recommendations

Install the antenna as high as practical and away from large obstructions. Use carrier aggregation-capable SIM/data plans where possible to benefit from increased throughput. Check supported LTE bands for your operator before installation and secure all outdoor cabling and mounts against wind and weather.
