MARTIN, C / O ASAC BELLSOUTH/CROWN COMMUNICATIONS s8L99V� 1903 PHOENIX BLVD., SUITE 250 ATLANTA, GA 30349 AERONAUTICAL STUDY No: 00 -ASO -7342 -OE ** DETERMINATION OF NO HAZARD TO AIR NAVIGATION ** The Federal Aviation Administration has completed an aeronautical study under the provisions of 49 U.S.C., Section 44718 and, if applicable, Title 14 of the Code of Federal Regulations, part 77, concerning: Description: NEW ANTENNA TOWER. SEE ATTACHED FREQUENCIES Location: SEBASTIAN FL Latitude: 27-49-07.37 NAD 83 Longitude: 080-28-26.57 Heights: 173 feet above ground level (AGL) 198 feet above mean sea level (AMSL) This aeronautical study revealed that the structure does not exceed obstruction standards and would not be a hazard to air navigation provided the following condition(s), if any, is(are) met: Based on this evaluation, marking and lighting are not necessary for aviation safety. However, if marking and/or lighting are accomplished on a voluntary basis, we recommend it be installed and maintained in accordance with FAA Advisory Circular 70/7460-1K. This determination expires on 05/14/02 unless: (a) extended, revised or terminated by the issuing office or (b) the construction is subject to the licensing authority of the Federal Communications Commission (FCC) and an application for a construction permit has been filed, as required by the FCC, within 6 months of the date of this determination. In such case the determination expires on the date prescribed by the FCC for completion of construction or on the date the FCC denies the application. NOTE: REQUEST FOR EXTENSION OF THE EFFECTIVE PERIOD OF THIS DETERMINATION MUST BE POSTMARKED OR DELIVERED TO THIS OFFICE AT LEAST 15 DAYS PRIOR TO THE EXPIRATION DATE. This determination is based, in part, on the foregoing description which includes specific coordinates, heights, frequency(ies) and power. Any changes in coordinates, heights, frequency(ies) or use of greater power will void this determination. Any future construction or alteration, including increase in heights, power, or the addition of other transmitters, requires separate notice to the FAA. This determination does include temporary construction equipment such as cranes, derricks, etc., which may be used during actual construction of the structure. However, this equipment shall not exceed the overall heights as indicated above. Equipment which has a height greater than the studied structure requires separate notice to the FAA. This determination concerns the effect of this structure on the safe and efficient use of navigable airspace by aircraft and does not relieve the sponsor of compliance responsibilities relating to any law, ordinance, or regulation of any Federal, State, or local government body. A copy of this determination will be forwarded to the Federal Communications Commission if the structure is subject to their licensing authority.

Newa u Jr. (DNE ) S cialist, Airspace Branch ATTACHMENT TV STATION SPURIOUS EMISSION: AERONAUTICAL STUDY NO. 00 -ASO -7342 -OE Evaluation of this proposal predicts in -band signals as indicated below for various frequency ranges. The additional attenuation required to reduce in -band spurious signal levels is also tabulated to reduce the maximum allowable level to —104 dBm. This level was established and agreed upon by the FCC and FAA in 1981 to eliminate the harmful interference to FAA facilities. The last column shows the total amount by which the spurious radiation must be attenuated below the unmodulated R.F. carrier for the frequency range specified. Location Frequency Spurious Additional Total Attenuation Range Level Attenuation Required Below MHz Required R.F. Carrier Vero Beach, FL 125.075 MHz -101.1 dBm 2.9 dB 62.9 dB This determination of No Hazard is granted provided the following conditional statement is included in the proponent's construction permit or license to radiate: Upon receipt of notification from the Federal Communications Commissions that harmful interference is being caused by the licensee's (permittee's) transmitter, the licensee (permittee) shall either immediately reduce the power to the point of no interference, cease operation, or take such immediate corrective action as is necessary to eliminate the harmful interference. This condition expires after one year of interference -free operation.
