Considerations for Changing Antenna Parameters
Let:
max Available Tx Power denote the maximum Tx Power practically available from an
ODU. It appears as Tx Power per Radio in Figure 5-10
below.
maxRegEIRP denote the maximum EIRP available by regulation. It will be determined by
three factors:
• per band/regulation
• per channel bandwidth
• antenna gain
It appears in Figure 5-10 as Max EIRP.
maxRegTxPower denote the maximum regulatory Tx Power for the equipment, also
having regard the above three points.
Then, the following relationship must be satisfied:
... (*)
These parameters are controlled as follows:
 To set Tx Power and configure antennas:
1. Click the Configure buttons in turn to configure the antennas on both sides of the
link. Each one offers a dialog like this:
Dual 64QAM 3/4 117
Dual 64QAM 5/6 130
