Polarity is critical to any linear LNBF.
If you have your polarity set right you will get the best performance
from your LNBF. Good polarity settings also help you find signal
faster if you are aligning the dish. Below is some pictures to
help you understand the polarity of the Xtreme II LNBF. Click any
picture to get a larger view.
Removing the cap lets you see the probe and how it aligns with the
polarity mark. Of course removing the cap breaks the water seal so
don't do this on your LNBF.
The
"0" polarity mark is on the housing. It's a lot easier to see on
the LNBF than in these pictures.
If you
don't know where to set your polarity, start by putting it up.
After you get signal go back and align the polarity for the best signal.
Don't forget to check both polarities. It's always a good idea to
check your dish alignment after making polarity adjustments.
This
is a Xtreme II on one of our test dishes. It's live on Intelsat 5
(Telstar 5) in Atlanta Georgia.
