16. Select Linear Radio and the Radio from the pull down menu.
The following step is critical to complete correctly. Failure to do so will compromise
the performance of the system
17. Calculate the Minimum Attenuation and Ranging Initial Attenuation. To accomplish this you will need
to know the following: Note: these values are obtained from the manufactures data sheet.
Radio Gain
Radio Max Power
IFL loss
Subtract the Radio Max power from the Radio Gain
Subtract the IFL loss from the value calculated in the previous step. This value will be the Minimum
Attenuation.
The Ranging Initial Attenuation is the Minimum Attenuation plus six (6)
Example: Radio Gain = 63 db Radio Max Power = 38 dbm IFL loss =10 db
63 – 38 = 25
25 – 10 =
15 Minimum Attenuation
15 + 6 = 21 Ranging Initial Attenuation
18. Enter these values and Select Next
19. The Tx Verification page will be displayed. Once the values are verified, select Next. The Rx Antenna
Pointing page is displayed.
20. This page will provide the coarse values to point the antenna using the DAPT.
21. Calculate the course polarization value
For Horizontal Receive:
Multiply the value listed by negative one (-1)
For Vertical Receive:
Multiply the value listed by negative one (-1)
Add or Subtract 90 based on your location in relation to the Satellite.
