[BC] WEEI towers (2)

[Dan Strassberg]

Another interesting bit of trivia about the WEEI array is that, despite
having an average electrical height of 207 degrees (according to CDBS), the
efficiencies are rather low for towers of that height. If the electrical
height really were 207 degrees, you'd expect to see efficiencies of
approximately 400 mV/m/kW @ 1 km. Instead, the night efficiency is
approximately 370 mV/m/kW @ 1 km and the day efficiency is approximately 386
mV/m/kW @ 1 km. Both efficiencies are greater than the Class A minimum even
though WEEI is a Class B, but one would expect greater efficiency than that
listed in CDBS. I have often wondered whether the actual efficiencies are
somewhat higher than those listed in CDBS, and if they are, why are lower
values listed?
