Alignment
Tips
• We recommend using a pair of installers in constant
communication because in the fine-tuning stage, one installer
makes azimuth and elevation adjustments on one airFiber radio
while the other installer reports the received signal level at the
other airFiber radio. (Fine-tuning is necessary because the main
lobe of the receiver is more narrow than that of the transmitter,
in both azimuth and elevation.)
• To accurately align the airFiber radios for best performance, you
MUST align only one end of the link at a time.
• For more convenient alignment, you may consider using
long-range scopes (not included) temporarily attached to your
airFiber radios.
• You may need to use additional hardware to compensate for
issues such as the improper orientation of a mounting pole or
significant elevation differences between the airFiber radios.
Establishing a Preliminary Link
Adjust the positions of the Master and the Slave to establish a
preliminary link. This requires the Master and Slave to be within a
few degrees of the line of sight between the airFiber radios.
Note: The Master must be aimed first at the Slave because
the Slave does not transmit any RF signal until it detects
transmissions from the Master.
1. Master Ensure the eight Lock Bolts on the Master's Alignment
Bracket are sufficiently loose by spinning each washer by hand.
WARNING:
to the airFiber housing.
