3. Connect the antennas either directly to the AP’s N-type connectors, or use RF

coaxial cable provided in the antenna package.

4. Apply weatherproofing tape to the antenna connectors to help prevent water

entering the connectors.

Note

Be sure to take account of the antenna polarization direction; all antennas in

a link must be mounted with the same polarization.

How to Align Antennas

When using the SMC2891W-AN unit with its 5 GHz integrated high-gain antenna,

you will need to accurately align the antenna with another unit in the network to

ensure optimum performance. Proper antenna alignment is particularly important

for long-range point-to-point links.

◆ Point-to-Point Configurations — In a point-to-point configuration the

alignment process requires two people at each end of the link. The use of cell

phones or two-way radio communication may help with coordination. To start,

you can just point the antennas at each other, using binoculars or a compass to

set the general direction. Then you can adjust the horizontal and vertical

position to find the position where the signal is strongest and secure the unit in

that position.
