Cisco Aironet 1600 Deployment Manual page 37

Remember the best antenna placement is the one where the antenna is physically closest to the actual
users. If you are mounting multiple single package dual band antennas externally such as dipoles,
spacing is not critical but try to space as far apart as practical (with "A" and "B" the furthest apart).
Figure 47 Antenna Placement
Avoid spacing antennas further than 10 Ft (antennas should be in same RF coverage area)
Note
Avoid using single band (single radiating element antennas) like those used with earlier 3500 series
Note
Access Point products as they are not fully compatible with the newer 1600/2600 and 3600 Series Access
Points. Antennas for the 1260 and 3500 series are single radiating element antennas made for each
individual band. The 3600, 2600 and 1600 use dual band - dual radiating element antennas and are
branded with an orange marking see Figure 45 and Figure
