Inserting a Client Adapter
Step 3 Press the antenna cable into the receptacle on the top of the base as shown in Figure 3-13.
Step 4 Press the antenna straight down into the receptacle until it clicks into place.
Mounting the Antenna
Because the PCI card is a radio device, it is susceptible to RF obstructions and common sources of
interference that can reduce throughput and range. Follow these guidelines to ensure the best possible
performance:
• Place the PCI card’s antenna in an area where large steel structures such as shelving units,
bookcases, and filing cabinets will not obstruct radio signals being transmitted or received.
• Place the antenna away from microwave ovens and 2.4- and 5.8-GHz cordless phones. These
products can cause signal interference because they operate in the same frequency range as the PCI
card.
Follow the steps below to position the PCI card’s antenna on a flat horizontal surface or to mount it to a
wall.
Step 1 Perform one of the following:
• If you want to use the antenna on a flat horizontal surface, position the antenna so it is pointing
straight up. Then go to Step 7.
• If you want to mount the antenna to a wall, go to Step 2.
Step 2 Drill two holes in the wall that are 1.09 in. (2.8 cm) apart. Figure 3-14 shows the distance between the
mounting holes on the bottom of the antenna base.
