3.
If you previously changed the radio polarization setting, the polarizer clamp
next to the TRIA (shown in Figure 21, upper left) should be loose. If the clamp
is not loose, loosen it now by loosening the two Allen screws.
4.
Perform steps a and b at the same time:
a.
Fit the feed horn stem against the polarizer, as shown in Figure 21.
The polarizer end fits into the feed horn stem.
Figure 21: Place the feed horn on the support bracket
b.
Place the feed horn onto the feed horn support bracket so the two holes
nearest the feed horn fit into the pegs on each side of the bracket.
Note:
If you have difficulty, loosen the clamp where the polarizer joins the TRIA, or
loosen it more.
Attaching the clamp
With the feed horn in place, attach the clamp that secures the feed horn to the
polarizer.
Attach the clamp exactly as stated in the following steps. Failure to do so could
allow moisture to accumulate inside the TRIA and/or feed horn, causing damage to
the radio.
