Connecting an Antenna with the 3G Wireless WAN HWIC 3G Wireless WAN Interface Cards REVIEW DRAFT-CISCO CONFIDENTIAL Figure 131 shows the various antenna options with the 3G wireless WAN HWIC. Figure 131 Antenna Options Connecting Swivel-Mount Dipole Antennas If you are using Cisco swivel-mounted dipole antennas, follow these steps: Step 1 Step 2 Attach an antenna to each TNC antenna connectors on the front of the 3G wireless HWIC and tighten it hand-tight. Orient the antennas, depending on how you intend to mount the router in which the 3G wireless HWIC is installed. • If the router is on a table or desk, orient the antennas to the left and right sides so that they are at a 90-degree angle to each other. (See Figure 131.) • If the router is on a vertical surface, such as a wall, orient the antennas up and at a 90-degree angle to each other. • If the router is on a ceiling, orient the antennas down and at a 90-degree angle to each other. Note Although it is not absolutely necessary, for best RF performance, do not attach the dipole antenna directly to the face-plate of the 3G wireless HWIC. Use the antenna extension cable and antenna base recommended for the product. OL-12853-01 14
