8. Re-Checking Hardware and Locking Down Antenna Position

8.1 Re-check all installation steps against this manual ensuring all bolts and hardware are properly aligned and tightened.

33


8.2 Aim the antenna at the determined satellite by adjusting the EL jack screw（changes the elevation angle）and AZ adjust screw (changes the azimuth angle). Tighten the EL and AZ lock-nuts when pointing is peaked on the satellite.

IMPORTANTThe Installer must be sure to tighten the EL lock-nuts (two pcs. on the EL jack-screw) AZ lock bolts and nuts after the antenna is aimed at the satellite and peaked for maximum signal level.

Please follow steps below when performing.Refer to Figure-27 through Figure-30A) Tighten two Nuts with P/N 10-01 for locking EL angle.B) Tighten two Nuts with P/N 10-02 for locking AZ angle.C) Tighten Bolt with P/N 10-03 then Nut with P/N 10-04 for locking AZ angle further.

8.3 In combination with the pointing and peaking of the AZ and EL axes on the satellite, the OMT

(combined with Feed-horn) may be rotated for maximum signal level and cross-polarization isolation.

ADJUSTMENT

1. Adjusting the azimuth and elevation pointing angles:1.1 Ensure the antenna is positioned such that the vertical support is true and vertical and that the

horizontal (azimuth) support plane is level.1.2 Predict the elevation and azimuth angle from the earth station to the satellite using the equations

below. You may determine your earth station location using a map or GPS receiver. Note, the azimuth and elevation angles calculated are with respect to true north. You may need to adjust your magnetic compass readings for the magnetic variation of your earth station location.

1.3 Adjust the elevation angle of the antenna to point to the satellite.1.4 Adjust the azimuth angle of the antenna to point to the satellite.1.5 Using a spectrum analyzer or satellite signal-meter, adjust the pointing angles precisely, then

tighten the jack-screw lock-nuts. Note, you may need to orient the polarization angle as described below first in order to obtain adequate signal level.

2. Adjusting the polarization angle:2.1 Loosen the bolts of the feed-horn mount slightly just so it can be rotated freely but does not

physically wobble in its mount.2.2 Using a spectrum analyzer or satellite signal-meter, carefully rotate the feed-horn clockwise and

counterclockwise to peak the polarization.2.3 The procedure in 2.2 should be done repeatedly and carefully by monitoring the signal with a

Spectrum Analyzer or appropriate satellite signal-meter. You satellite operator may also require you to adjust the polarization end-to-end over the satellite with their control station.

Calculation of Earth Station to Geostationary SatelliteAzimuth and Elevation Pointing Angles

Step-1, Subtract the geostationary longitude from the earth station longitude and take the magnitude:

= (1)

Where: = Satellite longitude; decimal degrees East,

= Earth station longitude; decimal degrees East.

Step-2, Calculate the elevation angle:

= (2)

Where: = Elevation angle; decimal degrees. = Earth station latitude; positive decimal degrees North or South.

40


Step-3, Calculate the interim of the azimuth angle:

= (3)

Where: = Interim azimuth angle; decimal degrees.Step-4, Apply quadrant correction to the interim azimuth angle to obtain the true azimuth angle :

Figure-1, Interim Azimuth ( ) Correction by QuadrantExample:

In this example we will let:

= Satellite longitude = 118.00 deg. East,

= Earth station longitude = 106.86 deg. East.

= Earth station latitude = 6.85 deg South.

Step-1, Subtract the geostationary longitude from the earth station longitude using Equation-1:

= = deg.

Step-2, Calculate the elevation angle using Equation-2:

= = deg.

= Northand :

= 180 +

= Southand : =

= Southand :

= 360 -

= Northand :

= 180 -


Step-3, Calculate the interim of the azimuth angle using Equation-3:

= = deg.

Step-4, Apply quadrant correction to interim azimuth angle using Figure-1:

Since = North and > 0, we apply the correction in the upper-right quadrant of Figure-1 above.

Therefore,

= = = deg.

MAINTENANCE

Generally, the antenna requires little maintenance, but the operator should note the following:

1. The antenna may be used normally through wind speeds up to 20 m/s.2. If wind speeds exceeding 20 m/s are expected, the antenna should be stowed to straight vertical

(at zenith). This should be done before high wind is evident.3. In areas of very high wind (e.g., typhoons), the maximum antenna survival wind speed is 35 m/s

when stowed to straight vertical.4. For operation at Ku-band, it may be necessary to dehydrate the feed/OMT assembly.5. It may be found that some subassemblies may accumulate water. Should that occur, the user

should drill a small hole at the lowest point of the assembly for drainage. This may be the case with the main reflector at high elevation pointing angles and in regions of high rainfall rate.

6. In areas that experience heavy snow-fall, it is important the reflector and feed assembly be kept clear of snow and ice. Be sure not to damage or stress the antenna when brushing or removing snow and ice. In some instances de-icing heating equipment may be necessary.

7. Twice a year at equinox, sun transit may cause brief temporary signal interruptions. Contact your satellite operator for details regarding times, dates, and durations.

8. It is recommended that once a year, the user should check and re-adjust (if necessary) the antenna pointing and polarization angles.

9. Keep the reflector panel and feed clean and free of dirt, grease, or non-approved paints to ensure maximum performance.

10. Once a year, all bolts, screws, and nuts should be greased and/or coated to prevent rust.11. It is important to ensure the feed horn cover (radome) is intact and free from holes or cracks. If the

feed cover is replaced, before returning the antenna to service with the new feed cover installed, it is advisable to check the OMT assembly for any water accumulation.
