tw all of the necessary data is avail-

Again, here in Porto, the azimuth an-
gle of the motor is -31, that is, 31 de-
grees to the east. With the help of the
button on the underside of the motor,
the antenna is manually moved to this
position. A single push of the button
moves the antenna to the east while a

quick double-push of the button moves
the antenna to the west.
At this point the motor is correctly
aligned and the antenna itself is now
adjusted just like a normal fixed anten-
na. So, the entire motor/antenna as-
sembly is turned left and right while the
elevation of the antenna is adjusted up
and down until ASTRA 19.2 east comes
into focus.
It’s easier, of course, to adjust the
antenna using a signal analyzer es-
pecially when it can deliver real-time
measurements. Theoretically, the ad-
justment work on the antenna is now
finished; now the receiver needs to be
configured for motorized reception.
In reality, though, the situation is
quite different: if the antenna is moved
to the extreme eastern and western
satellites, it won’t take long to notice
that the motor and antenna actually
don’t follow the satellites in a perfect
The antenna most likely needs to be
fine-tuned up or down for these outer
satellites. Regardless of whether the
