Aligning and PeakingAligning and Peaking

Prior to Aligning:

• Clear line of sight

• ODU securely mounted

• Mast is level and plumb

• Elevation is set

• Tilt is set

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
