WTTA-TV (WB 38) in Tampa, FL, installed an Ai two-tube ESCIOT depressed collector analog/digital Quantum transmitter in June.
The installation replaced a three-tube pulsed Klystron system that provided 120kW peak sync output power. The new transmitter, using two e2v ESCIOT water-cooled tubes, provides the same output power as the old system but results in significant utility cost reductions.
A direct comparison of power bills between August 2003, when the old transmitter was in service, and August 2004 showed monthly savings of more than $13,000. This represents annualized savings of $156,000, enough to pay for the new system in four years.
The Ai Quantum series of transmitters using the e2v ESCIOT is designed to operate in either digital or analog service. Equivalent energy savings are available in either mode of operation.
