Antenna alignment might be performed only in favourable weather conditions. Adverse weather
conditions are considered to be e.g. the rain, fog, snow, smog, etc. when the value of the measured
signal varies significantly, and so the measurement is very inaccurate!
NOTE:
When aligning the antennas watch out for the possibility of "false" alignment on the side
lobes from remote antenna. It is important to identify main antenna lobe, by rotating the antenna
to have the maximum RSL voltage. The value of RSL should always correspond to the expected
calculated value of received signal strength.

The functional test
Before connecting the user's ports and the link commissioning it is recommended to do a quick test of
the basic device functions to verify proper microwave link installation and its error-free condition. For
that, it is again necessary to connect your PC and check the basic radio parameters.
