NAB Announces 2005 Engineering Achievement Awards
Washington - Feb 7, 2005 - Each year, the NAB presents its Radio and Television Engineering Achievement Awards. The awards, first established in 1959, are presented to individuals for their significant contributions that have advanced the state of the art of broadcast engineering. This year’s winners, Oded Bendov and Milford Smith, will be honored at the NAB2005 Technology Luncheon on April 20 in Las Vegas where Dr. Robert W. Lucky, engineer, author and commentator on the state and future of data communications technology, will provide the keynote address.
Radio Engineering Achievement Award Winner: Milford K. Smith
Milford K. Smith is vice president of radio engineering for Greater Media, one of the nation’s largest privately owned radio companies. He has held this position for the past 19 years. For the 11 years preceeding this position, he held a similar position with First Media, another large private radio group owner. Prior to that he spent several years with Tribune Broadcasting in New York. He has also been a major contributor to industry advisory and standardization activities. He is the senior co-chairman of the National Radio Systems Committee DAB Subcommittee, a position he has held for nearly a decade, and is a past chairman of the NAB Digital Radio Committee, an advisory committee to the NAB's Radio Board of Directors.
Smith is known for his engineering talents and people skills. Long before the industry consolidation of the 90s He was taking disparate and sometimes dilapidated radio properties and transforming them into engineering showpieces. From the initial pre-purchase evaluation to the purchase itself, to establishing temporary studio facilities to keep the station on the air, to location of new studio/office space, to design and build out of the new space, to upgrade of the transmission system, he would (and still does) embark upon ambitious consolidation projects, doing a great majority of the work himself.
Some of the more exciting and innovative engineering projects tackled by Smith include the Peachtree Plaza hotel FM transmission system, considered by many for over 20 years to be the finest RF facility in the Atlanta market; the Prudential Center FM transmission system, where he led the effort to design and replace an existing transmission facility for four FM stations while all remained on the air, then some years later adding three more stations without causing disruption to the other facilities; and, the relocation of KLSX Los Angeles to Mt. Wilson, where he came up with a unique strategy to relocate this station from an inferior site, in the process creating a full-market signal. More recently Smith and his staff at Greater Media have been involved in an ambitious IBOC digital radio build out. In 2005, Greater Media expects to be the first radio group to have fully converted all their stations to IBOC.
Television Engineering Achievement Award Winner: Oded Bendov
Dr. Oded Bendov is president of TV Transmission Antenna Group, a company established in 2003 and dedicated to the development of new technologies, design, and consulting services to broadcasters and television set manufacturers. In 2004, the Metropolitan TV Alliance (MTVA), the umbrella group of New York City broadcasters, awarded Bendov a contract to design the master antenna tower atop the Freedom Tower, the new building to be built on the site of the World Trade Center. Planned to be completed in 2009, the main digital TV transmission facilities will serve the New York metropolitan area from the top of the Freedom Tower in lower Manhattan, with an overall height height, including antenna, exceeding 2,000 feet.
Bendov received his Ph.D. degree from Northwestern University in 1967, the year he joined RCA. For most of his career, Bendov worked for RCA and then Dielectric. He worked at the RCA Antenna Engineering Center, which in 1986 was acquired by Dielectric Communications where he was senior vice president and chief scientist. Bendov has been a major contributor to the analysis and design of a large number of analog and digital antenna installations, the most complex being at the World Trade Center in New York City and Mt. Sutro in San Francisco. Bendov was also the principal architect of the industry’s transition to circularly polarized TV antennas. Circular polarization for television transmission was recognized with an Emmy Technical Achievement Award in 1984.
Bendov holds several patents and has published many technical papers on television antennas, propagation, and interference. He is the author of chapters on transmitting antennas in the TV Engineering Handbook and the Encyclopedia for Electrical and Electronics Engineering.
