Antenna Alignment - Solectek skyway User Manual

After 5 minutes of scanning, the radio will automatically disable the scan and return to normal
operation. A scan can be terminated sooner by clicking the Stop button on radios with local
Ethernet access.

11. Antenna Alignment

SkyWay Access contains several tools to aid with the antenna alignment process that is essential for
client units.
Audible Alignment: The radio produces an audible tone allowing antenna alignment without the
need for additional monitoring hardware.
Note: A ping, or other network traffic is needed to ensure reliable operation of the alignment
feature, in which case the Activity indicated will be in a green state. If no network traffic is
detected, the Activity indicator will be in a red state.
Tip: It is useful to fix the position of the base station sector antenna for the intended coverage area
first and move onto the client unit antenna alignment.
The pulsed tone will begin once an RF link has been established, regardless of quality. It is useful to
reduce the RF Data rate setting to its lowest value during the antenna alignment procedure to
maximize the system's link capture envelope/angle.
The audible repetition rate will increase as RSSI improves; a higher value will cause a faster rate.
To assist with both coarse and fine tuning, the rate is NOT a simple function of RSSI value. Rather,
the rate will continue to increase as long as adjustments deliver an improved RSSI. As soon as any
degradation (alignment 'overshoot') is detected, the rate quickly falls, regardless of the amount of
reduction. Thus, the system is useful for both coarse and fine tuning of the antenna position.
To ensure the system will deliver adequate link reliability, it is recommended that the operator verify
the numerical RSSI following antenna alignment.
The audible function is enabled for the first 30 minutes of operation following a power cycle. If
desired, the audible function can be manually disabled using the telnet command: set audioalign 0
or via the Alignment Page (below).
Regardless of whether the audible function is enabled or disabled, the unit will emit a short audible
tone upon initial power-up.

page. Navigate to Installation -> Antenna Alignment to display the following page:
