11 Pointing the Antenna
with Web iSite
This chapter explains how to point the antenna using Web iSite. The chapter is applicable
when commissioning the Evolution X1, X7, and e150 Satellite Routers.
This chapter includes the following sections:
•
“Preparation” on page 59
• “Initial Alignment” on page 59
• “Peak Indicators” on page 61
• “Peaking the Antenna” on page 62
11.1 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 Peaking:
1. If the Satellite Router is on, disconnect power.
2. Ensure that the Receive IF cable is connected from the LNB to the Satellite Router.
3. Ensure that the Transmit IF cable is connected to the Satellite Router.
4. Disconnect the Transmit IF cable from the BUC and connect it to the DVM.
5. Reconnect power to the Satellite Router.
11.2 Initial Alignment
Web 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.
11.2.1 Calculating Look Angle
Web iSite calculates look angle based upon geographic location data extracted from the
options file, or entered manually by the user.
