Step 2. Mounting the Antenna
Follow the instructions below to mount the antenna.
Note: You can use a 24db grid antenna to achieve a link as long as the remote brouter can
hear it.
a) On a side-building mount, position the bracket so there will be at least three feet (one
meter) above the roof line where the pole is attached. This enables room for the antenna
and reduces signal loss from building reflection.
Note: It is not recommended to mount the antenna onto any unstable object. For more infor-
mation on antennas, see Polarizations on a Grid Antenna, page 2-9.
b) Allow for as much space between the wall brackets as possible while maintaining the
appropriate antenna height. For extended poles, additional wall brackets may be necessary.
c) Assemble the antenna and mount it to the pole using the included U-bolt antenna mounting
hardware. For a semi-parabolic grid type antenna, align the grid to run parallel with the
grid on the tip of the antenna horn. Preferably, the grid should be horizontal (or parallel to
the ground). Make sure all bolts and screws are fastened tightly.
d) Fasten the pole to the brackets. Position the antenna, point it in the appropriate direction,
and tighten the screws. Then, aim the antenna so it is pointed toward the receiving antenna
on the other building. The radio signal radiates from the end of antenna like a wide-
beamed flashlight. For optimal performance, you may need to test your link using both
polarities. This configuration option varies with each location, as well as RF signals that may
be present in the area.
