2.7 Step 7: Attaching Transceiver (LNB) to antenna
The Transceiver has one F-connector. Polarization depends on the sector in which are you
doing CPE installation. On the Transceiver (LNB) you define polarization by turning it.

Caution
Max angle of the sector is 90 degrees; the user should be within the angle if not the
user could have transmitting or receiving problems. If the user is connected in an
area where antennas overlap the polarization with better values should be chosen.
