Good Point. Manual says;
The Signal Strength Ratio (calculated over a one hour period) is: Power received by the vertical antenna input (dB) ÷ Power received by the horizontal antenna input (dB) This ratio is presented as: max, mean, min, and latest. The max, min and latest are true instantaneous measurements; the mean is the mean of a set of one second means.

If all of the power levels are nearly the same, how can the ratio be that far off? That makes no sense. Unless it doesn't mean the same thing as with SSR on the PMP450 (V-H or B-A Rx power ratio).

The manual says; Signal Strength 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. I was thinking bad cable? Maybe antenna or radio.

Bad Signal Strength Ratio. One end is 6.4 the other 19.5 Issue is probably at one end. Question is which end to check first. I have attached the System Stats of each end. Anyone able to see which end may have the problem from these? Thanks Adam
