The Receive Antenna Pointing screen opens.
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 49.
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 on page 46), 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:
