Rough peak the satellite reflector for signal on the EA 72.7ºW or the WA 119ºW .
Rough peak the satellite reflector for signal on the Eastern Arc 72.7ºW or the Western Arc 119°W
satellite signal using the azimuth and elevation settings you wrote on page 4. Do not adjust the
skew.
Note
: If you cannot find the Eastern Arc 72.7ºW or the Western Arc 119°W signal, try adjusting
the elevation up or down one or two degrees. When peaking on Eastern Arc 72.7ºW, use
transponder 5 or 9. When peaking on the Western Arc 119°W, use transponder 13 or 21.
Tighten three mast bolts and reconfirm signal strength . With the peaking meter still
connected, confirm that the front two mast bolts (the mas
t
bolts that are closest to the reflector) are
tight. Tighten the three mast bolts labeled with a T to the torque values listed in Table 1 (see Figure
8). Reconfirm signal strength after tightening the bolts. Peaking goal at this point is to get signal
locked. Maximizing signal is in a later step.
