What is the quality of radar data from the new Quantum radar compared to the RD418HD unit in conditions of inclement weather, i.e. heavy rain. This is a concern due to the low power level of the quantum units.

With the lower power it will not be as good as a 4kW HD radar at seeing soft targets at distance (e.g. birds, rain, etc.) From our testing the maximum range Quantum has been able to identify a rain storm is approximately 6 miles.
