This high-quality, low-loss 50-ohm cable is for use with the Cisco Aironet 12 dBi High Gain Omnidirectional Antenna. The antenna terminates with a special connector (reverse-TNC plug) after a short, 1-ft. cable. The mating connector to the antenna is an appropriate reverse-TNC jack connector.After the cable is attached to the antenna, make sure that the connections are sealed (if using outdoors) to prevent moisture and other weathering elements from affecting performance.
