7 Pointing the Antenna
with iSite
This chapter explains how to point the antenna using iSite.
This chapter includes the following sections:
•
“Preparation” on page 31
• “Initial Alignment” on page 31
• “Peak Indicators” on page 33
• “Peaking the Antenna” on page 34
7.1 Preparation
The following procedure assumes that the BUC and LNB are in the operational state. The
following items are required for this procedure:
• DC Voltmeter
• 75 Ω “F” female voltmeter input adapter
To Prepare for Pointing:
1. Disable Windows Firewall on the local PC. See “PC Firewall” on page 4 .
2. If the Satellite Router is on, disconnect power.
3. Ensure that the Receive IF cable is connected from the LNB to the Satellite Router.
4. Ensure that the Transmit IF cable is connected to the Satellite Router TX Out port.
5. Disconnect the Transmit IF cable from the BUC and connect it to the voltmeter.
6. Reconnect power to the Satellite Router.
7.2 Initial Alignment
iSite provides a Look Angle Calculator to compute the initial azimuth, elevation, and polarity
settings for the antenna. The initial settings provide a starting point from which to begin fine-
pointing or ‘peaking’ of the antenna.
7.2.1 Calculating Look Angle
iSite calculates look angle based upon the geographic location data entered by the user. If the
antenna site geographic coordinates are unknown, they may be determined with a GPS
