Figure 131 Antenna Options
Connecting Swivel-Mount Dipole Antennas
If you are using Cisco swivel-mounted dipole antennas, follow these steps:
Step 1 Attach an antenna to each TNC antenna connectors on the front of the 3G wireless HWIC and tighten it
hand-tight.
Step 2 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.
