2.4GHz 15dBi Outdoor Omnidirectional Antenna

A 2.4GHz 15dBi outdoor omnidirectional antenna is engineered to deliver reliable wireless connectivity in external environments, combining a balanced gain with rugged durability. Operating exclusively in the 2.4GHz ISM band (2.4-2.4835GHz), it supports common standards like Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac), making it compatible with most consumer and industrial wireless devices. The 15dBi gain strikes a practical balance between range and coverage, offering extended reach (up to 1-2 kilometers in line-of-sight) while maintaining a broader vertical beamwidth (10-15 degrees) than higher-gain alternatives, reducing alignment sensitivity.

Its outdoor design features a robust, UV-resistant housing—often made of fiberglass or aluminum—to withstand harsh weather conditions, including rain, snow, extreme temperatures (-40°C to 60°C), and high winds. A built-in lightning arrester is commonly integrated to protect connected equipment from electrical surges, a critical feature for exposed installations.

The antenna’s omnidirectional pattern ensures 360-degree horizontal coverage, making it ideal for applications like outdoor Wi-Fi hotspots, smart city sensors, agricultural monitoring systems, or connecting remote buildings. It typically uses an N-type or SMA connector for easy integration with routers, access points, or transceivers. Mounting options include pole brackets or wall mounts, with a recommended height of 3-10 meters to optimize line-of-sight with client devices.

Performance-wise, the 15dBi gain enhances signal-to-noise ratio (SNR), reducing packet loss and improving data throughput in congested areas. However, users should avoid overcrowded 2.4GHz channels to minimize interference from neighboring networks.  this antenna balances power, durability, and ease of installation, making it a versatile solution for extending outdoor wireless networks.
