4.4.2 IFU Alignment Procedure
1. Loosen the horizontal alignment nut on the mounting bracket.
2. Sweep the IFU a minimum of 10 degrees horizontally and note the highest of the peaks.
NOTE: As you sweep the antenna, you will notice the voltmeter display fluctuates. Once
you attain modem lock, the voltmeter display will stabilize. This is a feature of the IFU which
allows you to identify when modem lock occurs. (It is possible to achieve modem lock on a
side lobe. Therefore, it is necessary to complete the full alignment procedure to ensure proper
alignment on the main lobe.)
