SkyWay-GB-R Quick Start Guide
5. Align Antennas & Coarse Alignment
Refer to your antenna manufacturer’s installation guide to per-
form the following:
1. Set the radio terminal to the pre-defined azimuth, or use
binoculars or a signal mirror to locate the far-end radio location.
2. If you can see the far-end radio terminal, estimate the align-
ment visually and tighten the pole mount brackets with the fine
adjustment bolt set to the middle of the adjustment range.
3. Ensure the horizontal adjustment bolts are snug; only
tighten the bolts one quarter of a turn.
4. Slightly adjust each antenna up or down for best vertical
alignment, and left or right for best horizontal alignment, by
finding the maximum RSL voltage reading.
6. Cross Section of RF Beam
Note:
Before you begin to align the antennas, it is highly rec-
ommended to first identify your target RSL level.
Coarse Alignment:
•
If you do not have the path design calculated levels,
you can also obtain the site coordinates and use
Google Earth to estimate the path distance.
•
Align both far and near ends of the link, one
antenna of the link at a time.
•
Ensure azimuth lock bolts are tight while
adjusting elevation and vice-versa.
•
Perform several passes from one end of the
link to the other.
•
For short paths, lower TX power to 0 dBm or to
calculated level where far-end RSL = -40 dBm.
To ensure antennas are not aligned on a side-lobe, rough
align at least 10° in azimuth and elevation of the visually per-
ceived alignment center beam.
