Sec.  80.771   Method of computing coverage.

   Compute the +17 dBu contour as follows:

   (a) Determine the effective antenna height above mean sea level according to
   the procedures in  Sec.  Sec. 80.757–80.761.

   (b) Determine the effective radiated power according to  Sec. 80,765. Determine
   for each radial the distance from the antenna site to the +17 dBu point of
   field strength using procedures of  Sec.  Sec. 80.765 and 80.767.

   (c) Plot on a suitable map each point of +17 dBu field strength for all
   radials and draw the contour by connecting the adjacent points by a smooth
   curve.
