Step 10: Align the Antenna
Antenna alignment is the process of physically aligning the antenna of the radio receiver and transmitter to have the best
possible link established between them. The antenna alignment process is usually performed during installation and after
major repairs.
If you are installing external antennas, consult the documentation that accompanies the antenna for installation
instructions. Note that you must weatherproof the antenna connectors as described in Step 12: Weatherproof the
Connectors.
To ensure correct antenna alignment:
1. Perform a link budget calculation.
2. Compare the calculation to the SNR value on the SS by logging into the SS Web interface and clicking Monitor >
Statistics > MAC Statistics.
3. If needed, physically adjust the antenna, and refresh the Monitor > Statistics > MAC Statistics page to take a new
reading.
Step 11: Tighten the Cables
1. Apply two wraps of Teflon tape around the threads of the unit’s RJ45 jack (A) in a clockwise direction.
2. Make sure that the red rubber gasket is still seated in the sealing cap of the sealing cap/lock nut assembly (B);
3. Slide the sealing cap/lock nut assembly (B) over the RJ45 jack (A) and thread onto enclosure. Hand tighten first, then
use a pipe wrench or similar tool to tighten one more quarter turn.
CAUTION: Do not over-tighten!
4. Tighten the lock nut (C) (Torque 4 N
.
m/35 in-lbs).
5. Thread the sealing nut (D) onto the sealing cap/lock nut assembly (B) and tighten (Torque 3 N
.
m/25 in-lbs).
CAUTION: The lock nut (C) on the sealing cap/lock nut assembly (B) must be fully tightened over the RJ45 connector
before the sealing nut (D) is fully tightened. Otherwise, the Ethernet cable may twist and damage.
