The antenna operates in both the 2. 4-GHz and 5-GHz frequency bands and is designed for use with Cisco Aironet 2. 4-GHz and 5-GHz radio products that have dual-band reverse-polarity TNC (RP-TNC) antenna ports. The antenna has a nominal gain of 2 dBi in the 2. 4-GHz frequency band and 4 dBi in the 5-GHz frequency band. The three antennas covered in this document are electrically the same.
