The main item in the graphical indicator is Input Signal stripe.
The height of the Input Signal stripe is measured by Input Signal Level scale in
dB. The higher is the stripe the stronger is the signal.
The stripe can change it location along the Cross Fading scale that shows how
much influence the corresponding device antenna has on the other one, i.e. how
much vertically and horizontally polarized signals influence each other. The
higher value has the stripe according to the Cross Fading scale (the farther stripe
is from the 0 dB value) the less influence antennas have on each other.
The top of the Input Signal stripe can be located in black (Good signal) or red (Bad
signal) background areas or somewhere in washed border between them. It means
the signal is good, bad or average correspondingly. When aligning the antenna it
is recommended to try to achieve the stripe top to be located in the black area.
At the bottom of the Input Signal stripe may appear a special red sub-stripe. This
sub-stripe indicates the presence of packet retries and its percentage of the total
transmitted packets number.
