As far as the 50kW / non-D / 24-hr operations are concerned, their

The list below illustrates my statement above. This data for most of the
50kW, 24-hr stations with the same radiation pattern day and night was taken
from a secondary source linked to the FCC database, current as of October
2004 (typos, if any, excepted).

The average height of these radiators is 188.8°, not including
WFAN and KDKA.
