How well can the network see Beaver Dam?
The nearest Doppler radar is KMKX (Milwaukee, WI), 37 miles to the SSE. A WSR-88D's lowest routine scan sits half a degree above horizontal, and the earth curves away beneath it, so by the time that beam reaches Beaver Dam its center is about 2,400 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Beaver Dam to show rotation in the part of a storm where tornadoes actually form. Beaver Dam is closer to its radar than 60% of US cities.
The closest instrument actually measuring the air is KUNU · Juneau/Dodge Cnty on the ASOS/AWOS network, 7.0 miles away. Near enough to be representative on most days, though a summer thunderstorm can soak one and miss the other entirely.
Beam height is the standard 4/3-earth approximation for the 0.5° scan and assumes normal refraction; it is where the center of the beam is, not its edges, and unusual temperature profiles bend it. Radar siting from the NWS WSR-88D network, station positions from the Wisconsin observing network as of this build.
