ensure a strong signal. Ensure that access is available for routing the antenna cable from the antenna to the access point.

2If they are installed, remove both arms of the standard detachable antenna, making sure not to handle the tips of the antenna.

3Connect one end of the optional antenna cable to the antenna and secure the antenna in place.

4Connect the free end of the antenna cable to the right-hand side connection on the access point, as shown in the illustration above.

5Make certain that the antennas and antenna masts are appropriately grounded to prevent injury or damage from lightning strikes.
