Transmitter Efficiency Calculator Web Page Now Available

--NAB FASTROAD-funded tool helps predict transmitter system energy costs--

WASHINGTON, DC -- NAB FASTROAD today unveiled a new, Internet-based Transmitter Efficiency Calculator that broadcasters can use to predict approximate transmitter system energy costs both for present operations and for the "what if" evaluation of prospective, future purchases. With funding from the NAB FASTROAD technology advocacy program, this web tool was developed by the broadcast engineering consulting firm of Cavell, Mertz & Associates (CMA), and builds upon the data presented in a FASTROAD-funded Transmission Efficiency White Paper authored by CMA and released earlier this year.

The FASTROAD Transmitter Efficiency Calculator is useful for planning of AM, FM, and DTV transmission facilities, both analog and digital. The database that serves as the engine for the Calculator utilizes data provided by equipment manufacturers, which may be expanded in the future as manufacturers provide additional information.

Transmitter site power consumption and costs may be quickly and easily approximated using the Calculator based on the answers to a series of simple questions relating to the broadcast transmitter configuration, geographical location, the building structure in which the transmission equipment is housed, and the on-site cooling capabilities.

The Transmission Efficiency Calculator, the full text of the CMA White Paper, entitled "Power Efficient Broadcast Facility Transmission Design," and information on the NAB FASTROAD technology advocacy program are available at The Calculator will be discussed at the 2011 NAB Show in the NAB Broadcast Engineering Conference (April 9-14, 2011, Las Vegas, NV) on Thursday morning, April 14th as part of the "Green Technology" session.

NAB FASTROAD (Flexible Advanced Services for Television & Radio On All Devices) is the technology advocacy program of the National Association of Broadcasters. The overall mission of the FASTROAD program is to seek and facilitate development and commercialization of new technologies that can be exploited by broadcasters using radio and television broadcast spectrum.
