Meaning
The maximum, mean, minimum and latest measurements of
V/H Ratio. See
Diagnostics calculated over time
This is calculated from:
Power received by the vertical antenna input (dB) ÷
Power received by the horizontal antenna input (dB)
V/H Ratio is an aid to debugging a link. If it has a large
positive or negative value, then investigate the following
potential problems:
An antenna coaxial lead may be disconnected.
When spatial diversity is employed, the antenna with the
lower value may be pointing in the wrong direction.
When a dual polar antenna is deployed, the antenna may
be directed using a side lobe rather than the main lobe.
When there is a reflection from water on the link and spatial
diversity is employed, then one expects large, slow swings in
V/H Ratio. This indicates the antenna system is doing exactly
as intended.
