The Cisco Omni Directional Antenna - HGA9N, allows you to increase the range of the Wireless network for your business. Simply attach the antenna to the WAP54GPE Exterior Access Point to increase both the effective strength of the outgoing signals and boost sensitivity to incoming signals. The added signal strength and sensitivity you receive from the HGA9N Omni Directional Antenna also improves mid-range communication reliability because every packet comes through "loud and clear", reducing retransmissions due to weak signal reception errors. 9dBi signal strength allows the signals to travel further and detect the signals stronger in a 360-degree radius. The included weatherproof housing is able to withstand harsh outdoor conditions.
