Antenna Performance

The Cisco AIR-ANT2566D4M-R Aironet 2.4 GHz/5 GHz Dual Band Directional Array Antenna is a high-performance antenna designed for use with Cisco Aironet access points. Here are some key features and specifications of the antenna:

  • Frequency range: 2.4 GHz to 2.5 GHz and 5.15 GHz to 5.85 GHz
  • Gain: 6 dBi at 2.4 GHz and 6 dBi at 5 GHz
  • Polarization: Linear, vertical and horizontal
  • Beamwidth: 70 degrees horizontal and 60 degrees vertical at 2.4 GHz, and 70 degrees horizontal and 40 degrees vertical at 5 GHz
  • Connector type: RP-TNC
  • Dimensions: 10.8 x 10.8 x 2.2 inches

The antenna's directional array design helps to focus the wireless signal in a specific direction, providing increased signal strength and range. The dual-band capability of the antenna means that it can be used with both 2.4 GHz and 5 GHz wireless networks, which allows for greater flexibility in network design and deployment.

The gain of 6 dBi at both frequency ranges means that the antenna provides a significant increase in signal strength compared to the standard dipole antenna that comes with many wireless access points. The linear polarization with both vertical and horizontal options further helps to ensure that the antenna is able to pick up the wireless signal in the desired direction.

The beamwidth specifications indicate that the antenna provides relatively wide coverage in the horizontal direction, which makes it well-suited for use in large open spaces. The narrower vertical beamwidth at 5 GHz means that the antenna provides a more focused signal in the vertical direction, which can be useful for providing coverage to specific floors in a multi-story building.

Installation and Mounting Considerations

The Cisco AIR-ANT2566D4M-R Aironet Dual Band Directional Array Antenna is designed to enhance the signal strength and coverage area of Cisco Aironet access points. Before installing and mounting the antenna, there are some considerations that need to be taken into account:

  • Compatibility: Ensure that the antenna is compatible with the Cisco Aironet access point being used. The antenna is designed to work with dual-band 802.11a/g/n/ac access points that have four antenna connectors.
  • Location: The antenna should be placed in a location that provides the best signal coverage. Factors such as height, obstruction, and distance from the access point can affect the signal strength and coverage area.
  • Cable Length: The length of the cable between the antenna and access point should be kept as short as possible to minimize signal loss. Cisco recommends using low-loss coaxial cable, such as LMR-400, for cable lengths up to 100 feet.
  • Orientation: The antenna should be oriented in the direction of the desired coverage area. The antenna provides a directional beam pattern that can be adjusted for horizontal or vertical polarization.
  • Mounting: The antenna can be mounted using a pole mount or a wall mount. When mounting the antenna, ensure that it is securely fastened to prevent it from falling or moving due to wind or other environmental factors.
  • Grounding: To prevent damage from lightning strikes, it is recommended to ground the antenna using a grounding wire connected to a suitable grounding point.

Antenna Management and Configuration

The Cisco AIR-ANT2566D4M-R Aironet 2.4 GHz/5 GHz Dual Band Directional Array Antenna is a high-performance antenna that is designed for use with Cisco Aironet access points. This antenna is capable of operating on both 2.4 GHz and 5 GHz frequency bands, making it ideal for use in a variety of wireless networking applications.

Antenna Management:

The management of the Cisco AIR-ANT2566D4M-R Aironet antenna is done through the access point software. The access point software provides information about the antenna, including its status, signal strength, and other parameters. The software can also be used to configure the antenna, including setting the frequency band, gain, and other settings.


The Cisco AIR-ANT2566D4M-R Aironet antenna can be configured for use in either 2.4 GHz or 5 GHz frequency bands. The antenna has a directional array, which means that it can be used to direct the wireless signal in a specific direction. The gain of the antenna can also be adjusted to increase the strength of the signal.

To configure the Cisco AIR-ANT2566D4M-R Aironet antenna, the following steps should be followed:

  • Log in to the access point software.
  • Navigate to the antenna configuration page.
  • Select the frequency band that the antenna will be used in (2.4 GHz or 5 GHz).
  • Set the gain of the antenna to the desired level.
  • Configure any other settings that are required.

Once the antenna is configured, it can be used to improve the performance of the wireless network by directing the signal in the desired direction and increasing the strength of the signal.
