Dome Antenna OEM D12-8-26-NF2 4G 12 dBi 800–2600 MHz

Dome Antenna OEM D12-8-26-NF2 is a 4G external dome-style antenna with 12 dBi gain that operates across 800–2600 MHz. It is designed to improve cellular signal reception for LTE bands and other mobile technologies that use these frequencies. The compact dome form factor allows mounting on roofs, masts or flat surfaces and is suitable for stationary and semi-mobile installations where improved mobile data stability and reduced call or connection dropouts are required.

Advantages

The antenna provides a high directional gain of 12 dBi across a broad 800–2600 MHz band, enabling stronger received and transmitted signals compared with standard low-gain antennas. Its dome enclosure offers a low-profile and weather-resistant appearance for outdoor mounting, while the broadband coverage supports multiple 4G/LTE bands and many legacy cellular channels. The design simplifies installation on rooftops or poles and is compatible with equipment that accepts external antennas in the specified frequency range.

Suitable for

• Improving 4G/LTE data reception at homes and small offices
• Boosting cellular connectivity for remote sites and rural locations
• Supporting mobile routers, gateways and modems that accept external antennas
• Temporary or semi-permanent installations on roofs, masts or vehicles

Key specifications

• Frequency range: 800–2600 MHz
• Gain: 12 dBi
• Form factor: dome-style external antenna
• Typical applications: 4G/LTE cellular bands and compatible mobile services
• Mounting: roof, mast or flat-surface mounting options
• Environment: outdoor-rated enclosure suitable for exposed installations

How to use

Select a mounting location with a clear line of sight toward the nearest cellular base station if possible, such as a roof ridge or an elevated mast. Secure the dome antenna using appropriate brackets or mounting hardware, route the antenna cable to the modem or router, and attach using compatible connectors. After connection, verify signal strength and adjust orientation or height to optimize reception. Ensure cable runs are protected and sealed at entry points to prevent water ingress.

Usage recommendations

For stable 4G performance, place the dome antenna as high as practicable and away from large metal obstructions. Use low-loss coaxial cable and maintain secure, weatherproofed connections. If signal levels remain weak, try small adjustments to azimuth and elevation or consider combining with an additional antenna or amplifier per equipment compatibility.
