Figure 6-1: Antenna Elevation Offset - iDirect iNFINITI 3000 Installation And Commissioning Manual

NOTE
The 1.8 meter antenna has 22.6° offset and a 1.2 meter antenna has 17° offset. For example, an
elevation angle of 50° would be set as follows:
° °
50 - 22.6 = 27.4
The back plane is perpendicular to the line of sight of the antenna plus 22.6°.
If the back plane is at 90°, the antenna elevation angle is at 22.6°.
In the example above the antenna would be elevated from 90° to 117.4° or depending on the type
of inclinometer being used a reading of 62.6° to reach an elevation angle to 50°.
3. To prepare the antenna for pointing, move the antenna off the desired azimuth,
by swinging the antenna 20° away in azimuth. This will enable you to get a clear
sky reading and compare signal strengths during the antenna pointing procedure.

To take into consideration the magnetic angle of declination in
your location and to ensure that the compass reading is correct,
you must
1. Take a reading at the back of the antenna
2. So that you have something to point to, mark a
reference point some distance ahead of the antenna.
Keep in mind that large metal objects can throw off compass
readings.
