Special Displacement Window Application

LPTV or Translator Facility: WIBW-TV Facility ID 63160 Topeka KS Existing Digital Replacement Translator Licensed Ch. 44 File# BLCDT-20100505AHK

Nature of Displacement: Within 600 MHz wireless spectrum

Proposed Facility: Ch. 33 15 kW ERP nondirectional

Modification Compliance: 0.0 km from licensed site Contour comparison in Figure 1 Proposed DRT contour does not extend beyond former analog Grade B contour TVStudy Analysis report in Table 1 Proposed WIBW-TV DRT displacement has priority over the following non-DRT displacement application: K40IJ-D Ch. 33 Topeka KS 0000030155

Contingent Application Rule: No waiver required, not dependent on spectrum to be vacated

RF Exposure: The calculated signal density near the tower at two meters above ground level attributable to the proposed facility is 0.1 percent of the general population/uncontrolled maximum permitted exposure limit. Calculations conducted pursuant to FCC OET Bulletin Number 65 and incorporate 20 percent relative field at downward angles (from antenna elevation pattern data). This is below the five percent threshold limit described in §1.1307(b) regarding sites with multiple emitters, categorically excluding the applicant from responsibility for taking any corrective action in the areas where the proposal’s contribution is less than five percent.
