Installing the Ku-Band Co-Pol/Cross-Pol Feed Assembly
Refer to the procedure below to install the Ku-Band Co-Pol/Cross-Pol feed assembly on the 2.m
meter offset reflector.
1.
Assure that the DAC-2202
System Type does NOT
include 8.
2.
Assure that the DAC-2202
TX Polarity is set to 2
(Horizontal TX).
3.
If this is the initial
installation of a drop-in feed,
skip to step 12.
4.
If switching drop-in feeds,
remover the currently
installed drop-in by
following step 5-10.
5.
Disconnect the coax
connections to the LNB(s).
6.
Disconnect the flexible
waveguide from the rigid
waveguide.
7.
Disconnect the feed harness.
8.
Tie the reflector down, or
have someone hold it until
the drop-in feeds have been
swapped.
CAUTION: The dish will be very back
heavy when the drop-in feed is
removed, therefore, the reflector will
rise VERY abruptly if not held down
until the weight of the feed is
replaced.
9.
Remove the eight screws
(see red arrows) from the
front of the scalar plate to
disconnect the drop-in feed
from the scalar plate.
