Product Features
Technical Overview
This antenna operates across VHF and UHF frequency bands, covering the 2.4 GHz to 2.483 GHz and 5.15 GHz to 5.875 GHz ranges. The dual-band capability allows it to support both legacy 2.4 GHz devices and modern 5 GHz networks, providing flexibility for mixed-device environments. The 7 dBi isotropic gain boosts signal propagation, helping to overcome obstacles and extend effective communication distances in outdoor settings.
The omni-directional directivity ensures uniform signal distribution in all horizontal directions, simplifying installation by eliminating the need for precise directional aiming. This characteristic is particularly beneficial for applications requiring coverage in circular or multi-directional areas, such as public Wi-Fi hotspots or perimeter security systems. The N-Type connector provides a secure, low-loss interface compatible with standard coaxial cabling, ensuring minimal signal degradation between the antenna and access point.

FAQ
What frequency bands does this Cisco antenna support?
This antenna supports dual-band operation across VHF and UHF ranges, specifically covering 2.4 GHz to 2.483 GHz and 5.15 GHz to 5.875 GHz. This allows it to work with both traditional 2.4 GHz Wi-Fi networks and modern 5 GHz bands, providing flexibility for various wireless standards and reducing interference in crowded RF environments.
What is the antenna gain and how does it affect performance?
The antenna has a gain of 7 dBi (isotropic), which measures how effectively it focuses radio frequency energy compared to an ideal isotropic radiator. This higher gain improves signal strength and extends the effective communication range, making it suitable for outdoor deployments where signals need to travel farther or penetrate obstacles more effectively than standard lower-gain antennas.
Is this antenna directional or omni-directional?
This is an omni-directional antenna, meaning it radiates signal uniformly in all horizontal directions. This design simplifies installation by eliminating the need to point the antenna toward a specific area, making it ideal for applications requiring broad, 360-degree coverage such as outdoor plazas, parking lots, or perimeter security systems where devices may be located anywhere around the antenna.
What type of connector does the antenna use?
The antenna uses an N-Type connector, a robust coaxial connector commonly used in RF and wireless applications. This connector type provides a secure, weather-resistant interface with low signal loss, ensuring reliable performance when connected to compatible Cisco Aironet outdoor access points or other equipment with matching N-Type ports.
What are the typical deployment scenarios for this antenna?
Typical deployments include extending corporate or campus Wi-Fi to outdoor areas, providing public internet access in parks or hospitality venues, supporting wireless surveillance cameras, and enabling IoT connectivity in industrial settings. Its outdoor durability and compatibility with Cisco Aironet access points make it suitable for permanent installations in harsh environments or temporary setups for events.
Is this antenna compatible with non-Cisco access points?
While specifically designed for compatibility with Cisco Aironet outdoor access points, the antenna uses standard N-Type connectors and operates on common frequency bands, so it may work with other access points that support similar RF specifications. However, optimal performance and warranty support are guaranteed only when used with certified Cisco Aironet outdoor models as indicated in the compatibility details.
