The three buttons on the DAPT can serve different purposes
during different phases of the pointing process. In most cases,
however, they function as follows:
•
Back (button 1) – Used to return to a previous state.
•
Toggle (button 2) – Used to toggle between signal filters.
•
Advance (button 3) – Used to begin a process, proceed to the
next state, or respond Yes to a prompt on the DAPT display.
Squinter The squinter is an antenna pointing aid used to electrically
fine-point the antenna once coarse pointing is completed. When
placed on the antenna feed horn, the squinter inhibits a portion of
the RF signal, thereby capturing the satellite signal from different
portions of the antenna reflector surface. The squinter is placed
alternately in four different positions: two for measuring azimuth
and two for measuring elevation. As shown in Figure 2, there are
three different types of squinters, each designed for use with
specific antennas.
Note: Be sure to use the correct squinter for the antenna you are
pointing, as described in Figure 2.
