Cisco Aironet AIR-ANT2547VG-N Dual-Band Omni Antenna – 4 dBi (2.4 GHz) / 7 dBi (5 GHz), N-Type, Gray

Better all-around Wi-Fi coverage for outdoor campus.

The Cisco AIR-ANT2547VG-N is a dual-band omnidirectional antenna with 4 dBi (2.4 GHz) / 7 dBi (5 GHz) gain and an N-type (male) connector, designed for Cisco Aironet outdoor access points with N-type connectors, such as the 1560 and 1570 series. It suits outdoor campus, industrial and municipal Wi-Fi.

Why the Right Antenna Matters for Wireless Coverage

An access point is only as good as its antennas. The wrong pattern sends signal where no users are, while low gain leaves weak spots at the edge of coverage. Outdoor and large indoor spaces are especially sensitive to antenna choice.

The AIR-ANT2547VG-N provides 4 dBi (2.4 GHz) / 7 dBi (5 GHz) with an omnidirectional (360°) pattern. Omnidirectional antennas radiate evenly in all horizontal directions, which suits access points mounted in the center of the area they serve.

Designed for Cisco Aironet outdoor access points with N-type connectors, such as the 1560 and 1570 series, it connects directly with an N-type (male) connector and is built for outdoor conditions.

Gain and Coverage Pattern

At 4 dBi (2.4 GHz) / 7 dBi (5 GHz), the AIR-ANT2547VG-N extends usable range compared with low-gain antennas. Plan placement using the 360° pattern so coverage matches where users or client radios are located.

Installation Considerations

Use the matching connector type, keep cable runs short to limit signal loss, weatherproof outdoor connections, and set the correct antenna gain in the access point configuration to stay within regulatory power limits.

How to Install the Cisco AIR-ANT2547VG-N

1. Confirm your access point or radio supports external antennas with a N-type (male) connector.
2. Mount the antenna in the planned position and orientation (vertical for omni coverage).
3. Connect the antenna to the access point or radio, tightening connectors by hand and weatherproofing outdoor joints.
4. Set the antenna type and gain in the management interface, then verify coverage with a site survey or signal readings.
