FAQ
What frequency bands does this Cisco antenna support?
The Cisco AIR-ANT2547V-N= antenna operates across two frequency ranges: 2.4 GHz to 2.483 GHz and 5.15 GHz to 5.875 GHz. This dual-band coverage supports both traditional 2.4 GHz Wi-Fi networks and modern 5 GHz implementations, providing compatibility with various wireless standards including 802.11a/b/g/n/ac. The antenna handles UHF and SHF frequency bands, making it versatile for different wireless applications and environments.
What is the gain of this antenna and how does it affect performance?
This antenna provides 7 dBi of isotropic gain, which represents a measurable increase in signal strength compared to a theoretical isotropic radiator. The gain enhancement improves wireless range and signal quality, particularly valuable in outdoor deployments where signals must travel longer distances. Unlike directional antennas that focus energy in specific directions, this omni-directional design distributes the gain improvement uniformly in all horizontal directions, simplifying installation while still providing meaningful performance benefits.
What type of connector does this antenna use?
The antenna features an N-Type connector, which is a standard RF connector known for its durability and excellent electrical performance. N-Type connectors provide secure mechanical connections with good impedance matching, making them well-suited for outdoor installations where environmental factors could compromise connectivity. This connector type ensures reliable signal transmission between the antenna and compatible Cisco Aironet outdoor access points, maintaining signal integrity in various weather conditions.
Which Cisco devices is this antenna compatible with?
This antenna is specifically designed for compatibility with Cisco Aironet outdoor access points. It integrates seamlessly with Cisco's outdoor wireless infrastructure products, providing enhanced antenna performance for extended coverage deployments. The compatibility ensures proper impedance matching and mechanical fit, allowing network administrators to upgrade or expand existing Cisco wireless networks without compatibility concerns or performance compromises.
What does omni-directional mean for this antenna?
Omni-directional refers to the antenna's radiation pattern, which distributes radio frequency energy uniformly in all horizontal directions (360 degrees). This pattern differs from directional antennas that focus energy in specific beams. The omni-directional design simplifies installation since precise directional alignment isn't required, while still providing the 7 dBi gain improvement. This makes the antenna ideal for applications requiring uniform coverage around an installation point, such as outdoor public areas or perimeter security systems.
What are the physical dimensions of this antenna?
The antenna measures 11.10 inches (281.94 mm) in height with a diameter of 1.25 inches (31.75 mm). These compact dimensions create a streamlined cylindrical profile that minimizes visual impact while providing sufficient radiating element length for optimal performance at the supported frequencies. The size makes the antenna suitable for various mounting scenarios including poles, building exteriors, or other outdoor structures where space considerations and aesthetics are important factors in deployment planning.
