6.1 Meter Earth Station Antenna
VS61FAE is a 6.1 meter earth station antenna
that provides superior performance through the use
of precision stretch-formed refl ector panels and a
dual-shaped Cassegrain feed.
The VS61FAE 6.1 Meter Earth Station Antenna
features corrugated conical feed horns to ensure excellent
antenna gain and sidelobe performance. Sixteen high-
strength aluminum panels are durable enough to withstand
a range of environmental conditions. Antenna panels
mount to radial trusses attached to a central hub.
The VS61FAE hub also provides a enclosure for sensitive
electronics.
high-strength structural steel tripod
mount employs an elevation-over-azimuth geometry for
easy pointing to any satellite within the visible orbital arc.
Rugged construction provides pointing
accuracy for continuous operation, even under adverse
wind conditions.
The VS61FAE includes a galvanized structural steel tripod
mount with a continuous 115° of motorized azimuth
coverage in three overlapping sectors. An optional
TORQUETUBE™ con fi guration adds continuous 180°
motorized azimuth coverage.

____________________________________________________________________________________________ SECTION 2 ANTENNA SITE SELECTION (120° AND 180° ANTENNA) One of the most important factors to be considered for trouble-free, high-quality GENERAL signal reception from desired satellites is the location of the antenna (i.e., the antenna site). For optimal signal reception, it is important that the antenna site selected provides the following: ••... - Page 9 ANTENNA SITE SELECTION (120° AND 180° ANTENNA) ____________________________________________________________________________________________ Figure 2-1.

ANTENNA SITE SELECTION (120° AND 180° ANTENNA) ____________________________________________________________________________________________ Once the operational clearance has been verified, it is necessary to verify a clear VERIFYING CLEAR line-of-sight. This ensures that the antenna may be aimed at desired satellite(s) LINE-OF-SIGHT without obstruction between the satellite(s) and any portion of the reflector. When using the satellite(s) aiming coordinates for a particular site, be sure that there are no trees, buildings, power lines, etc., between the dish location and the satellite. - Page 21 ANTENNA SITE SELECTION (120° AND 180° ANTENNA) ____________________________________________________________________________________________ Table 2-2.
