Receive antenna pointing – Ka-band
Note: This section applies to Ka-band installations only. For Ku-band, skip this section;
go to Receive antenna pointing – Ku-band on page 41.
To receive-point the antenna, you go the antenna location and point the antenna at its assigned
satellite using a squinter and DAPT (both are pointing tools) and then validate pointing on the
installer laptop as explained in this section.
The squinter blocks half the feed horn so you can measure Es/No at two azimuth positions and
at two elevation positions. When the antenna is pointed correctly, the two azimuth Es/No values
match, and the two elevation Es/No values match.
The DAPT displays SQF and Es/No values in real time and guides you through the pointing
validation process. The DAPT values are replicated on the DAPT Antenna Pointing Status
window (
Figure 28: DAPT Antenna Pointing Status window on page 38), also in real time.
To receive-point the antenna, use the screens illustrated in this section, and you must also follow
the procedure for squinter pointing that is documented in the Ka-Band Antenna Pointing Guide
for Bent-Pipe Satellite Networks (1038764-0001).
To receive-point the antenna:
1. On the Receive Antenna Pointing screen, click Display Signal Strength ( Figure 27: Receive
Antenna Pointing screen on page 38) to open the DAPT Antenna Pointing Status window.
