Installation Notes
Caution
We recommend avoiding installing wireless antennas in or near rack-mounted equipment that include
networking equipment and computer servers whose radiated noise emissions can severely degrade radio
performance.
•
To extend the coaxial cable included with your antenna, we recomend an ultra-low-loss coaxial
cable for installation flexibility without a significant loss in range. The following table lists insertion
loss information about ULL extension coaxial cables available from Cisco.
Figure 6
shows the ULL cable recommended for Cisco 3G Wireless WAN HWICs.
