Prepared for: NASHVILLE LICENSE HOLDINGS, L.L.C.
I am a Consulting Engineer, an employee in the firm of Carl T. Jones Corporation,
with offices located in Springfield, Virginia. My education and experience are a matter of
record with the Federal Communications Commission. I am a Licensed Professional
Engineer in the Commonwealth of Virginia, No. 7418, and in New York State, No. 63418.
GENERAL
This office has been authorized by NASHVILLE LICENSE HOLDINGS, L.L.C.,
licensee of WNAB, channel 23, facility ID number 73310, licensed to Nashville, Tennessee,
to prepare this statement, FCC Form 2100, Schedule A, its technical sections, and the
associated exhibits in support of an application for a minor modification of its post-
reassignment construction permit, File # 0000034797, that authorizes WNAB to use
channel 30 for its post-reassignment broadcasting. The instant application proposes to
substitute a Dielectric model TFU-28DSC/VP-R C180 antenna for its authorized antenna,
a Dielectric model TFU-26DSC/VP-R C170, to reduce WNAB’s antenna Centerline Of
Radiation (COR) from 366 meters Above Ground Lever (AGL) to 350 meters AGL and to
reduce WNAB’s Effective Radiated Power (ERP) from 725 kW to 510 kW. No other
changes are herein proposed.

DIRECTIONAL ANTENNA
The applicant proposes to substitute a new Dielectric model TFU-28DSC/VP-R
C180 directional elliptically polarized transmitting antenna instead of its authorized
antenna, a Dielectric model TFU-26DSC/VP-R C170 elliptically polarized directional
antenna. The horizontal azimuth directional patterns of the two antennas are different
which is accounted for in a new allocation study using tvstudy, as shown in Appendix B.
The substitute antenna’s center of radiation will be reduced from 366 meters AGL to 350
meters AGL. The antenna HAAT will be 411 meters. The antenna manufacturer’s antenna
data, including the horizontal azimuth patterns of both the horizontal and vertical signal
components and the vertical plane elevation radiation pattern, illustrating the antenna's
radiation characteristics above and below the horizontal plane are shown and tabulated in
the antenna exhibit.
PREDICTED COVERAGE CONTOURS
The predicted coverage contours were calculated in accordance with the method
described in Section 73.625(b) of the Rules, utilizing the appropriate F(50,90) propagation
curves (47 CFR Section 73.699, Figure 9), proposed Effective Radiated Power, and
antenna height above average terrain as determined for each profile radial. The average
terrain on the eight cardinal radials from 3 kilometers to 16 kilometers from the site, was
determined using the NED Three Second US Terrain Database as permitted in the FCC
Rules. The antenna site elevation and coordinates were determined from FCC antenna
registration data. Exhibit 1 shows the predicted Noise Limited (40.32 dBu) contour, and
the principal community contour, which completely encompasses Nashville, Tennessee.

ALLOCATION CONSIDERATIONS
Post-Transition DTV Considerations
A study was performed, using the FCC’s software, tvstudy, v. 2.2.5, to determine
if the instant modification application is predicted to cause prohibited interference to any
post-auction DTV stations, construction permits, DTV allotments or Class A DTV stations.
The study results, shown in Appendix B, indicate that the instant application for
construction permit is predicted to cause no new interference exceeding 0.5% to the
populations served by any post reassignment DTV station, construction permit, allotment
or Class A DTV stations. Note that the parameters used in tvstudy are:
Study cell size: 0.50 km
Profile point spacing: 0.10 km
The applicant requests that these parameters be used in the Commission’s evaluation of
the instant modification application. (See Appendix B)
BLANKETING AND INTERMODULATION INTERFERENCE
Other broadcast and non-broadcast facilities are either co-located with, or located
within 10 km of the proposed WNAB site. The applicant does recognize its responsibility
to remedy complaints of interference that might result from this proposal in accordance
with applicable Rules.
RADIO FREQUENCY IMPACT
The FCC’s guidelines and procedures for evaluating environmental effects of radio
frequency (RF) emissions are generally based on recommendations by the National

Council on Radiation Protection and Measurements (NCRP) in NCRP Report No. 86
(1986) and by the American National Standards Institute and the Institute of Electrical and
Electronic Engineers, LLC (IEEE) in ANSI/IEEE C95.1-1992 (IEEE C95.1-1991). The
guidelines define a maximum permissible exposure (MPE) level for occupational or
“controlled” situations, and for “uncontrolled” environments that apply in all other cases that
might affect the general public. The FCC Office of Engineering and Technology’s technical
bulletin No. 65 entitled, "Evaluating Compliance with FCC Guidelines for Human Exposure
to Radio Frequency Electromagnetic Fields" (Edition 97-01, August 1997), provides
assistance to determine whether FCC-regulated transmitting facilities, operations or
devices comply with guidelines for human exposure to radio frequency electromagnetic
fields as adopted by the Commission in 1996. OET Bulletin No. 65 contains the technical
information necessary to evaluate compliance with the FCC’s policies and guidelines.
The Maximum Permitted Exposure (MPE) level for broadcast facilities that operate
on a frequency between 30 MHZ and 300 MHZ is 200 microwatts per centimeter squared
(µW/cm2) for an “uncontrolled” environment, and is 1000 microwatts per centimeter
squared (µW/cm²) for a “controlled” environment. The MPE level for broadcast facilities
that operate on a frequency between 300 MHZ and 1500 MHZ, primarily UHF TV stations,
is determined for an “uncontrolled” environment by dividing the operating frequency in MHZ
by 1.5, and is similarly determined for a “controlled” environment by dividing the operating
frequency in MHZ by 0.3.
As shown in Appendix A the proposed WNAB channel 30 modified facility will
operate with a maximum ERP of 510 kW from an elliptically polarized directional

transmitting antenna with a centerline height of 350 meters above ground level (AGL).
Considering the elevation pattern submitted elsewhere in this application, the vertical plane
relative field factor is less than 0.100 at all depression angles greater than 8 degrees. The
WNAB facility is predicted to produce a worst-case power density at two meters above
ground level, at 200.9 meters from the tower base, of 1.317 µW/cm2, which is 0.35% of the
FCC guideline value of 379.33 µW/cm2 for an “uncontrolled” environment, and 0.070% of
the FCC’s guideline value for "controlled" environments. Therefore, pursuant to Section
1.1307(b)(3) of the FCC Rules, because the proposed facility would not exceed 5% of the
uncontrolled and controlled exposure limits, the proposal’s power density contribution is
considered insignificant. (See Appendix A)
Further, the applicant will continue to cooperate and coordinate with other any other
site users and reduce power or cease operation during times of service or maintenance of
the transmission systems as necessary to avoid potentially harmful exposure to personnel.
In light of the above, the proposed facility should be categorically excluded from RF
environmental processing under Section 1.1307(b) of the Commission’s Rules.
OCCUPATIONAL SAFETY
The licensee of WNAB is committed to the protection of station personnel and/or
tower contractors working in the vicinity of the WNAB antenna, and is committed to
reducing power or ceasing operation during times of maintenance of the transmission
systems, when necessary, to ensure protection to personnel.

RADIO FREQUENCY IMPACT, SAFETY & STATEMENT OF COMPLIANCE
The licensee of WNAB is committed to the protection of station personnel and/or
tower contractors working in the vicinity of the WNAB antenna and will reduce power or
cease operation, when necessary, to ensure protection to personnel.
As shown in Appendix A the proposed WNAB channel 30 modified facility will
operate with a maximum ERP of 510 kW from an elliptically polarized directional
transmitting antenna with a centerline height of 350 meters above ground level (AGL).
Considering the elevation pattern submitted elsewhere in this application, the vertical plane
relative field factor is less than 0.100 at all depression angles greater than 8 degrees. The
WNAB facility is predicted to produce a worst-case power density at two meters above
ground level, at 200.9 meters from the tower base, of 1.317 µW/cm2, which is 0.35% of the
FCC guideline value of 379.33 µW/cm2 for an “uncontrolled” environment, and 0.070% of
the FCC’s guideline value for "controlled" environments. Therefore, pursuant to Section
1.1307(b)(3) of the FCC Rules, because the proposed facility would not exceed 5% of the
uncontrolled and controlled exposure limits, the proposal’s power density contribution is
considered insignificant. (See Appendix A)
Further, the applicant will continue to cooperate and coordinate with other any other
site users and reduce power or cease operation during times of service or maintenance of
the transmission systems as necessary to avoid potentially harmful exposure to personnel.
In light of the above, the proposed facility should be categorically excluded from RF
environmental processing under Section 1.1307(b) of the Commission’s Rules.
