When the distance between radios exceeds 2200 feet, or where there are large obstructions like hills and trees, Wellntel suggests adding optional mounting kits — wire and brackets — to move the antennae up on both the Sensor and Gateway ends. Line of sight is always better. Lift both ends!
Battery life can be improved with a stronger signal, since the Sensor will re-try less often.
For very remote places, or places without Internet services, Wellntel offers systems that communicate using Cellular Networks. This kit measures Static levels and this one measure Static Levels and Pump Duty.
