A read-only CwrFixedPointValue, in dBm, giving the lowest receive power measured at the diversity antenna during the current operational hour, not a cumulative statistic. It shows how deep the diversity antenna's worst moment was across the whole hour, useful for seeing whether it fades in sync with the main antenna or covers for it during outages. For example, an hour where the main antenna's minimum dropped sharply but the diversity antenna's p2mpSu1HrDivAntRxPowerMin stayed comparatively healthy would show diversity combining successfully masking that hour's fade from the end user.
