1 Position the antenna so that there are minimal obstacles between it and any
client with which it will communicate. While maintaining a direct line of sight
between the antenna and a client is not strictly necessary, such an

for routing the antenna cable from the antenna to the access point.
2 If they are installed, remove both arms of the standard detachable antenna,
making sure not to handle the tips of the antenna.
3 Connect one end of the optional antenna cable to the antenna and secure
the antenna in place.
4 Connect the free end of the antenna cable to the right-hand side connection
on the access point, as shown in the illustration above.
5 Make certain that the antennas and antenna masts are appropriately
grounded to prevent injury or damage from lightning strikes. Proper
grounding for outdoor installations may require the purchase of a third-party
lightning arrestor.
