Cisco offers several different styles of antennas for use with both access
points and bridges in the 2.4 GHz product line, as well as the 5 GHz BR1400
bridge. Every antenna offered for sale has been FCC-approved. Each type of
antenna will offer different coverage capabilities. As the gain of an antenna
increases, there is some tradeoff to its coverage area. Usually gain antennas
offer longer coverage distances, but only in a certain direction.
