Omni-directional antenna Poynting A-OMNI-0414-V1-01 3.5 dBi SMA

The OMNI-414 is an ultra-wideband omni-directional antenna that covers contemporary LTE and 5G frequency bands from 617 to 3800 MHz. It features 4×4 MIMO capability from vertically separated radiating elements within a single radome, a male SMA connector and 50 Ω impedance. The compact radome (75 × 75 × 750 mm) with UV-stable ASA material and IP68 rating provides protection against dust, water and salt spray, making the antenna suitable for marine, coastal and other corrosive environments where broad frequency coverage and reliable reception are required.

Advantages

The antenna provides balanced gain across the entire 617–3800 MHz range and supports LTE Band 71 as well as CBRS bands (3400–3800 MHz), delivering future-proof ultra-wideband performance. Its 4×4 MIMO design improves throughput and reliability for multi-antenna systems while the single radome houses all elements to maintain a true omni-directional pattern. The IP68 rating and salt-water-resistant ASA radome ensure long-term durability in harsh weather and marine conditions.

Suitable for

• Marine and coastal installations on vessels and shore sites
• Fixed outdoor installations requiring omni-directional coverage
• Cellular 4×4 MIMO deployments for LTE and 5G bands including Band 71 and CBRS
• Environments with high UV exposure and salt corrosion

How to use

Mount the antenna in a clear, unobstructed location to preserve omni-directional coverage and secure it using appropriate marine-grade mounting hardware. Connect the antenna to your router, modem or radio equipment via the male SMA connector, ensuring compatible cabling and adapters if required. Verify that the connected device is configured for the supported frequency bands and MIMO operation. Periodically inspect mounting points and cable connections for corrosion or wear, especially in marine environments.

Recommendations

Install the antenna as high as practical and away from large metallic obstructions to maximize reception. For long cable runs or higher-power systems, use low-loss RF cable and suitable lightning protection. Follow local regulations for antenna installations and ensure weatherproofing of all external connections.
