reading on the voltmeter.
The antenna is properly pointed when the peak
voltage is between 0.2 volts and 3.9 volts, with no
oscillation.
voltage is between 0.2 volts and 3.9 volts, with no
oscillation.
c.
When the peak voltage reading remains steady
between 0.2 volts and 3.9 volts, tighten the azimuth
and elevation locking nuts (figure 7-5) to
16 foot–pounds (21.7 Newton–meters) torque.
between 0.2 volts and 3.9 volts, tighten the azimuth
and elevation locking nuts (figure 7-5) to
16 foot–pounds (21.7 Newton–meters) torque.
If you cannot obtain a steady voltmeter reading
between 0.2 volts and 3.9 volts, refer to table 7-1 for
the appropriate corrective action.
