Acquiring a Signal:
• Use your compass/inclinometer to point the ODU
• Connect the jumper to the LNB and meter
• Turn on meter
Acquiring a Signal:
• Use your compass/inclinometer to point the ODU
• Connect the jumper to the LNB and meter
• Turn on meter
• Peaking is the process of moving the azimuth and elevation by small amounts to achieve the highest overall signal

Exercise #1: Hands-on
• Watch the peaking process on an ODU outside
• Divide into groups of three
• Practice using a compass/inclinometer to verify line of sight
• Align and peak the ODU −more than once
