a.Each 3Com cable includes a separate 50 Ohm SMA terminator.
The 3Com antennas are dual-band, which means that they operate in both 2.4GHz and 5GHz spectra.
You can use these antennas with either the 802.11b/g radio or the 802.11a radio.
Each antenna requires the purchase of a separate antenna cable.
NOTE: Antenna cables introduce loss of the RF signal. Always use the shortest cable that your
application allows.
For installation instructions, see the documentation that is supplied with the antenna.
NOTE: During the installation, connect the antenna to the access point before connecting the
Category 5 Ethernet cable. This ensures that the access point is not powered on when the
access point is connected to the network.
