What is the tallest tower (in terms of AGL) identified on a sectional chart within the Class-E-to-surface airspace surrounding an airport in the US?
For the purpose of the question, "within the Class-E-to-surface airspace surrounding an airport" means within the part of the sectional chart that lies within a dashed magenta line that completely encloses the airport and is not separated from the airport by another dashed magenta or blue line. I.e. not including within Class-E-to-surface "extensions" that are separate from the Class-E-to-surface that actually surrounds the airport.
For simplicity, let's NOT include Class D or higher that reverts to Class-E-to-surface at night, etc.
"Tower" means any type of structure-- radio antennae, whatever-- that is depicted on the sectional chart with a tower symbol and has the AGL elevation of the top of the tower identified on the sectional chart.
