Adjust the elevation:
Note:
the AP and Station.
2. Station Visually aim the Station at the AP. To adjust the
Station's position, adjust the azimuth and elevation as
described in step 1.
3. Open the Configuration Interface. Select Tools and then
select Align Antenna.
4. Repeat steps 1-2 until you have achieved an optimal link
and both the 60G and 5G LEDs are solidly lit blue. This
ensures the best possible data rate between the radios.
Note:
by iteratively sweeping through both azimuth and
elevation.
5. Lock the alignment on both radios by tightening all the
nuts.
6. Observe the signal level of each radio to ensure that the
values remain constant while tightening the nuts. If any
value changes during the locking process, loosen the nuts,
finalize the alignment of each radio again, and retighten
the nuts.
Do NOT make simultaneous adjustments on
Maximum signal strength can best be achieved
