Ai QUANTUM Water Cooled ESCIOT MSDC Equipped Analog/Digital Transmitter Reconfirms Dramatic Power Savings at WTTA-TV -WB 38-; Earlier Results at WNUV-TV Duplicated.

COCKEYSVILLE, Md. -- WTTA-TV (WB 38) in Tampa, Florida installed an Ai two tube ESCIOT(R) Depressed Collector Analog/Digital transmitter in June of 2004. This 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 over $13,000. This represents annualized savings of $156,000, enough to pay for the new system in just 4 years.

The Ai Quantum(R) Series of transmitters using the e2v ESCIOT are designed to easily operate in either digital or analog service. Equivalent energy savings are available in either mode of operation.

Nat Ostroff, Chairman of Ai stated, "The field results that we are seeing from the ESCIOT equipped Quantum transmitters continue to exceed our expectations. These systems provide meaningful energy savings in both digital and analog service reliably and with low maintenance. Water-cooling in combination with Depressed Collector technology has proven to be the broadcasters' new friend. This new generation of UHF transmitter is rapidly setting industry standards for performance. Given the cost savings and the ability to operate in either digital or analog service the Quantum(R) Depressed Collector series is an ideal candidate to replace an aging analog system today and be converted to digital tomorrow. The power savings alone, in many applications, may pay for the new transmitter."

Director of Engineering at WTTA, Bob Hardie stated. "Not only has this transmitter reduced the operating costs, but its much lower heat generation has reduced the air conditioning costs of the building. This is very significant in Tampa, Florida. The difference is apparent as soon as you enter the transmitter room. Everything is just cooler. The systems operation has exceeded our expectations for reliability as well."
