Poynting OMNI-291 Omni-directional Antenna 7 dBi N-type Female

The Poynting OMNI-291 is a high-performance omni-directional antenna engineered for reliable signal reception across a wide frequency range of 0.45 to 2.7 GHz. Designed to meet the rigorous demands of marine and industrial environments, this antenna provides consistent LTE and GSM connectivity. It features a robust, weather-resistant construction and utilizes a standard 1-inch marine mount, ensuring compatibility with most marine hardware. By employing a unique, patented feed network and multiple dipoles, the OMNI-291 maintains superior pattern control and balanced gain, making it a versatile solution for global maritime communication needs.

Advantages

The primary benefit of the OMNI-291 is its exceptional versatility across a broad spectrum, including the critical 450 MHz LTE band often used in coastal regions. Its omni-directional radiation pattern eliminates the need for precise alignment toward a cell tower, simplifying installation and maintenance. The antenna's durable build quality ensures longevity even when exposed to harsh salt-spray and high-wind conditions typical of marine settings. Furthermore, the balanced gain across all supported frequencies ensures that users experience stable data speeds and reliable voice connectivity regardless of their location along the coast.

Suitable for

• Marine vessels and coastal communication systems
• Industrial IoT and M2M applications
• Remote monitoring stations requiring stable LTE/GSM signals
• Areas where 450 MHz LTE coverage is essential

This antenna may not be suitable for indoor residential use where space is limited or where a directional antenna is required to focus on a single, distant cell tower. It is also not designed for applications requiring frequencies outside the 0.45 to 2.7 GHz range.

Key specifications

• Frequency range: 0.45 - 2.7 GHz
• Antenna gain: 7 dBi
• Connector type: N-type female
• Mounting: 1-inch (14 TPI) marine mount
• Weight: 0.576 kg
• Colour: White

How to use

To install the OMNI-291, secure the antenna to a compatible 1-inch marine mount. Ensure the mount is positioned in an elevated, clear area on the vessel or structure to minimize signal obstruction. Connect a high-quality coaxial cable to the N-type female connector at the base of the antenna, ensuring the connection is tightened securely and weather-sealed if exposed to direct moisture. Once mounted, connect the other end of the cable to your LTE/GSM router or modem. No complex configuration is required as the antenna is passive and omni-directional.

What to consider before purchase

• Verify that your router or modem supports the N-type connector interface.
• Ensure you have a compatible 1-inch marine mount available for installation.
• Check that your local network provider operates within the 0.45 - 2.7 GHz frequency range.
• Consider the cable length required to reach your equipment, as signal loss may occur with very long cable runs.

Usage recommendations

For optimal performance, keep the antenna away from large metal structures or other antennas that may cause signal interference. Regularly inspect the N-type connector and the mounting hardware for signs of corrosion or wear, especially in salt-water environments, to maintain peak signal integrity.
