MINNEAPOLIS--(BUSINESS WIRE)--Jan. 18, 2000

ADC (Nasdaq: ADCT; www.adc.com) today announced that it has been chosen by Rapid Broadcasting to supply complete transmission systems for it's new stations in Sioux Falls and Rapid City, S.D. The total value of the systems ordered is approximately $1.3 million.

Rapid Broadcasting recently acquired licenses to build two new full service stations, replacing existing low power installations in South Dakota. KAUN, Channel 36, which is licensed to Sioux Falls and will carry PaxTV programming, requires a transmitter power output of 70kW. Channel 21 will be the NBC affiliate for Rapid City, and requires a 30kW transmitter. ADC was the first manufacturer to ship a transmitter with 70kW tube amplifiers (EEV IOT8707) and has installed many air-cooled transmitters using the 30kW amplifier (IOT9303).

"We have worked with ADC's low power transmitters for many years," said Mike Morgan, director of development for Rapid Broadcasting. "We chose ADC for these high power projects based on their overall technical capabilities as well as the quality and high level of customer support we have come to expect from them over the years."

Rapid Broadcasting chose ADC for these projects based on ADC's experience with two specific types of IOT amplifiers, mentioned above, in it's Visionary(TM) Series transmitters. These units use feed-forward driver amplifiers for highly linear performance, and are easily upgradeable to Visionary(TM) DTs for digital television.

"We are committed to utilizing the latest available technology, allowing us to provide the most attractive solutions to the individual needs of our customers," said Rich Dell, product manager for ADC's Broadcast Systems Division. "In the case of Rapid Broadcasting, we were able to provide 70kW output power from a single tube transmitter, rather than a two-tube transmitter supplied by other vendors. This results in significant savings for our customer."

ADC is a leading manufacturer of UHF and VHF television transmitters and exciters for both analog and digital television. The extensive product line features high power UHF transmitters using the IOT final amplifier, medium power transmitters in both solid-state and tube versions, and complete UHF and VHF exciter retrofits.
