§  90.689   Field strength limits.

   (a) For purposes of implementing § §  90.689 through 90.699, predicted
   36 and 40 dBuV/m contours shall be calculated using Figure 10 of
   §  73.699 of this chapter with a correction factor of -9 dB, and
   predicted 18 and 22 dBuV/m contours shall be calculated using Figure
   10a of §  73.699 of this chapter with a correction factor of -9 dB.

   (b) The predicted or measured field strength at any location on the
   border of the EA-based service area for EA licensees must not exceed 40
   dBuV/m unless all bordering EA licensees agree to a higher field
   strength. In the event that this standard conflicts with the EA
   licensee's obligation to provide co-channel protection to incumbent
   licensees pursuant to §  90.621(b), the requirements of §  90.621(b)
   shall prevail.
