ENGINEERING STATEMENT

The engineering data contained herein have been prepared on behalf of ALPHA

BROADCASTING CORPORATION, licensee of full-power digital WZVI-DT,

Channel 43 in Charlotte Amalie, , in support of its application for modification of

Construction Permit 0000027488, which authorizes operation on its post-repack channel,

Channel 21. It is proposed herein to operate from a new site with an increase in effective radiated power.

It is proposed to mount an omnidirectional, horizontally-polarized antenna at the

43.2-meter level of an existing 54.8-meter tower. The proposed effective radiated power for the facility is 6.0 kW in the horizontal plane. Exhibit B is a map upon which the predicted service contours are plotted. As shown, the community of Charlotte Amalie is completely encompassed by the proposed 48 dBu city-grade service contour.

An elevation pattern for the proposed antenna is provided in Exhibit C. Exhibit D contains the summary results from a TVStudy interference study, which was conducted using a cell size of 0.5 kilometers and increment spacing of 0.1 kilometers. It concludes that the proposed WZVI-DT facility meets the Commission’s de minimis interference criteria to all co- channel and adjacent-channel post-repack full-power and Class A facilities. A power density calculation appears as Exhibit E.

Since no change in the overall height or location of the existing tower is proposed herein, the Federal Aviation Administration has not been notified of this application. In addition, the Federal Communications Commission issued Antenna Structure Registration Number

1236533 to this tower. SMITH AND FISHER

POWER DENSITY CALCULATION

PROPOSED WZVI-DT CHANNEL 21 – CHARLOTTE AMALIE, VIRGIN ISLANDS [MODIFICATION OF CONSTRUCTION PERMIT 0000027488]

Since the FCC considers the possible biological effects of RF transmissions in its environmental determinations, we have studied the matter with respect to this Charlotte Amalie facility. Employing the methods set forth in OET Bulletin No. 65 and considering a main-lobe effective radiated power of 6 kW, an antenna radiation center 43.2 meters above ground, and the specific elevation pattern of the proposed ERI antenna, maximum power density two meters above ground of 0.00098 mW/cm2 is calculated to occur 20.5 meters from the base of the tower. Since this is only 0.3 percent of the 0.34 mW/cm2 reference for uncontrolled environments (areas with public access) surrounding a facility operating on Channel 21 (512-

518 MHz), a grant of this proposal may be considered a minor environmental action with respect to public exposure to non-ionizing electromagnetic radiation.

Further, the station owner will take whatever precautionary steps are necessary, such as reducing power or leaving the air temporarily, to ensure that workers operating in the vicinity of the antenna are not exposed to excessive non-ionizing radiation.
