Fixing a Warped Reflector
To correct a warped reflector, hold the dish like
a steering wheel and quickly thrust the reflector
away from your body like the motion of passing
a basketball. This quick action will cause the
reflector to slightly flex and spring back into the
factory pressed shape.
Check for correction with the string test. It may
be necessary to repeat the flexing process several
times until the reflector edges are uniformly flat.
When standing in front of the dish and looking
at the back of the LNBF and towards the
reflector, rotate the LNBF counter clockwise
(left) for a positive (+) LNBF Rotation
(Skew) setting and Clockwise (right) for a
negative (-) LNBF Rotation (Skew) setting.
Start with the LNBF slid back as far away
from the reflector as possible. Tighten the
screws to secure the LNBF from rotating. No
need to overtighten and break the clamp.
LNBF Rotation:
___________
The LNBF catches the satellite signals reflected from the dish and send the signal
down the coax to the receiver. It is important to properly install the LNBF. Insert
the LNBF into the clamp then lightly tighten the two screws to secure the LNBF.
LNBF Installation
Set the LNBF Rotation (Skew Angle) to the
setting specified in the aiming instructions
provided with your system. The LNBF rotates
in the circular clamp until the centering line
aligns with the LNBF Rotation angle. Failure
to set the correct LNBF Rotation will result
in not finding the satellite!
