Engineering Exhibit: Telemundo Las Vegas LLC Application for Experimental STA Description Telemundo Las Vegas requests special temporary authority to construct and operate a distributed transmission system to facilitate a real-world demonstration of mobile wireless video service in and around the Las Vegas Convention Center and on the Las Vegas strip during the National Association of Broadcasters Convention (NAB), April 18 through April 23, 2009. As this will be the first on-air demonstration of this technology for broadcasting ATSC Candidate Standard A/153 mobile/handheld compliant data streams STA is requested commencing April 10, 2009 for testing prior to the NAB Convention. This demonstration will be shut down no later than 4 PM, April 23, 2009. The distributed transmission system will consist of the licensed KBLR-DT facility operating at its authorized effective radiated power of 230 kW from Black Mountain with horizontal polarization, a temporary synchronized transmitter on top of the Stratosphere Tower at 2000 South Las Vegas Boulevard using vertical polarization with an effective radiated power not to exceed 1,000 watts, and a synchronized transmitter inf the Central Hall of the Las Vegas Convention Center transmitting a vertically polarized signal with an effective radiated power not exceeding 20 watts. Both transmitters will be located inside the KBLR-DT service contour. KBLR programming and the mobile wireless video programming will be transmitted via the AMC-16 satellite to the KBLR Black Mountain transmitter and the transmitter at the Convention Center. The transmitter at the Stratosphere will receive its signal either by terrestrial microwave or satellite. The system will be controlled at the KBLR studio and in the event of problems with the system or interference, KBLR will be able to immediately turn off the distributed transmission system and return to normal single transmitter operation using its existing STL to Black Mountain. The drawing on page 3 shows the system configuration. Interference Both low power transmitters will operate with vertical polarization only. This reduces interference to KBLR fixed ATSC reception while improving mobile and handheld reception. An interference study using the FCC LPTV pre-transition OET Bulletin 69 methodology showed no interference from the low power transmitter at the Stratosphere Tower to any station other than KBLR- DT. This is a worst case analysis because the methodology is based on all stations being horizontally polarized. A copy of the OET-69 study can be provided on request. Because KBLR-DT will be part of the distributed transmission system, the only interference to it will be in areas where ATSC receiver equalizers are unable to correct for signals from the multiple transmitters. The timing of the Stratosphere transmitter will be adjusted to minimize this interference. Interference from the low power transmitter inside the Convention Center was not studied as it will be insignificant due to its low effective radiated power and location within 2 km of the Stratosphere transmitter. It will, however, be locked to the other two transmitters in the system to reduce self- interference around the Convention Center. Preliminary analysis indicates minimum interference with the two low power transmitters delayed approximately 30 microseconds from the KBLR-DT full power transmitter. Interference will be checked at various locations as part of the testing prior to the NAB Convention. Should any unacceptable interference result, the demonstration will be shut down if interference cannot be resolved by reducing transmitter power at the Stratosphere or Convention Center.

Antenna System The transmitter at the Stratosphere will use two Kathrein-Scala CL-1469 log periodic antennas oriented at 164 degrees and 213 degrees true with the combined main beam at 189 degrees true. The antenna array will be tilted down a maximum of 8 degrees at 169 degrees true, resulting in the horizontal plane azimuth pattern attached. A polar plot of the elevation pattern at 189 degrees true is attached. The horizontal plane (azimuth) 3-dB beamwidth (without tilt) is 64 degrees and the vertical plane (elevation) 3-dB beamwidth is 67 degrees. The antenna array will be mounted approximately 909 feet above ground. The indoor transmitter at the Convention Center will use a Kathrein K-72-20-4 Type Number 767-006 omnidirectional antenna with a vertical plane 3-dB beamwidth of approximately 22 degrees. This antenna will be mounted at least 20 feet above the floor of the Convention Center. Manufacturer data sheets on both antennas are attached. RF Exposure RF exposure from the two low power transmitters in the distributed transmission system was studied using the formulas in OET Bulletin 65. The study showed that power density from the antenna at the Convention Center will not exceed FCC maximum permissible exposure level (0.419 mw/cm2) for an uncontrolled environment at any angle, including the main beam, if the antenna is mounted at least 6.1 meters (20 feet) from areas accessible to the public, as is proposed. At a maximum effective radiated power of 1,000 watts, the antenna at the Stratosphere is not predicted to produce power density exceeding the maximum permissible exposure level for an uncontrolled environment at any location 6.1 meters (20 feet) below the antenna on the Stratosphere. The antenna will not be mounted in an area accessible to the public. Due to the complex structure on top of the Stratosphere, a site survey will be performed to determine the distance and angle to the areas closest to the antenna accessible to the public. In the event the predicted power density exceeds 5 percent of the allowable exposure level for an uncontrolled environment, measurements will be taken in these areas to verify that the power density does not exceed maximum permissible exposure. A copy of the Excel interactive spreadsheet used to analyze RF exposure from these antennas can be provided on request. Telemundo Las Vegas certifies it will turn off these transmitters as required to protect workers from excessive RF exposure.

CL-1469B UHF-TV LOG-PERIODIC ANTENNA 8 dBd gain 470–862 MHz (Channels 14–69*) The Kathrein Scala Division CL-1469B is a ruggedly built, linearly polarized log-periodic antenna designed for professional UHF- TV transmit and receive applications. Like all Kathrein Scala Division antennas, the CL-1469B is made of the finest materials using state of the art electrical and mechanical designs resulting in superior performance and long service life. The rugged fiberglass radome protects the antenna from icing and assures stable pattern and gain performance under adverse environmental conditions. The CL-1469B may be used stand alone or in arrays for higher gain, increased side-lobe suppression, or custom azimuth patterns. *The CL-1469B covers all 6, 7, and 8 MHz UHF-TV channels worldwide (bands IV/V).
