7. Slowly turn the site A antenna back towards the position of site B, listen-
ing to the tone until the best signal is reached. See the following figure
for audible signal variations.

8. Secure the site A antenna to the pole/wall.
9. Repeat steps 4 to 8 for site B.
To align two external monopolar antennas:
1. Using a coax cable with N-Type connectors, connect one antenna to the
ANT 1 connector of the ODU.
2. Follow the steps 3 to 7 above to align the antenna connected to the ODU
connector ANT 1 on both sides of the link.
3. On both sides of the link, disconnect the antenna connected to the ODU
connector ANT 1. Connect the other antenna to connector ANT 1 and fol-
low the steps 3 to 7 above to align the second antenna.
4. Secure the antennas to the pole/wall.
5. Restore one of the antennas to ANT 2 on both sides of the link.
Note
• Three beeps and a pause is 'best signal so far'
• Two beeps and a pause is 'signal quality increased'
• One beep and pause is 'no change in signal'
• Long beep and short pause is 'signal quality decreased'
• One beep and a long pause is 'no air link'
• Any other signal does not relate to antenna alignment
Note
The ODU buzzer only works on the radio connected to the ANT 1 connector
marked
. You will therefore need to use ANT 1 to align both antennas
in turn. Upon completion of the alignment procedure, you may connect the
two antennas to ANT 1 and ANT 2 connectors.
