Mast Bracket Assembly
&
Antenna Positioning
( 1)
Loosely fasten the mast bracket halves ( 1) to the rotator housing
using four short bolts, split washers and fiat washers (2).
(2)
Insert the mast into the bracket, and finger-tighten the four longer
bolts (3) with split washers, fiat washers and nuts (4).
(3)
Set the controller so that it indicates precisely 0° (North). Then,
using an accurate map and known landmarks, position the antenna
(without using the controller) so that it points to true North.
Alternatively, consult a Geodetic Survey map for your area to
determine the Magnetic Deviation at your location, and then use
a compass to position the antenna so that it points to true North
(Magnetic North
+
Magnetic Deviation). Be careful not to disturb
the antenna direction when tightening the mast bracket in the
next step.
(4)
Referring to the mast .gauge markings on the rotator housing, tap
the mast bracket halves to center the mast white alternately
tightening the short bolts (2) and nuts (4) on the long bolts
alternately.
(5)
Confirm the calibration of the controller indicator by rotating the
antenna precisely 360° so that the antenna itself is pointing in
the same direction as before. If the indicator does not show
exactly 0° again, adjust the FULL SCALE potentiometer on the
rear of the controller slightly, and repeat this step.
