The materials and density of walls determine the number of walls signals can pass through.
Consider the following before choosing the location to install the antenna:
{
Signals can penetrate vinyl and paper walls with little affect to strength.
{
Signals can penetrate one or two solid or pre-cast concrete walls with strength not degraded.
{
Signals can penetrate three or four concrete walls with strength not degraded.
{
Signals can penetrate five or six wood walls with strength not degraded.
{
Signals cannot penetrate a metal wall even if the metal covering is very thin.
{
Signals cannot penetrate a wire mesh spaced between 2 and 3 cm (0.79 and 1.18 in).
•
Keep the antenna away from microwave ovens and 2.4-GHz wireless phones. These devices
operate in the same frequency range as the AP and antenna and can cause signal interference.
Choosing a mounting location
Follow these guidelines to choose a mounting location for the antenna:
•
For the best performance, mount the antenna to a position as high as possible, such as top of a
building, mountain, or tower. The higher an antenna, the better it performs.
•
Keep the antenna clear of metal obstructions.
•
Use a cable as short as possible to connect the antenna to the AP.
Mounting the antenna
You can install the antenna on a mast. The antenna is provided with mast-mounting installation
accessories. Prepare installation tools yourself.
For other installation methods, you need to prepare installation accessories yourself.
Installation accessories and tools
The antenna is provided with the following mast-mounting installation accessories:
•
One L-mounting bracket.
•
One mast-mount clamp.
•
One U-bolt kit that contains one U-bolt, two M6 nuts, two M6 spring washers, and two M6 flat
washers.
•
Four M6 x 8 nuts.
•
Four M6 flat washers.
•
Four M6 spring washers.
Prepare the following installation tools:
•
One 40 to 70 mm (1.57 to 2.76 in) diameter mast.
•
One combination wrench.
•
One inclinometer.
