Winegard Secures Exclusive Triple-Stacking Technology Rights

Winegard has signed an exclusive manufacturing and distribution deal with Global Communications, holder of eight patents on "Triple-Stacking Technology" covering the United States, Canada, Mexico and the Caribbean.

Winegard uses the trademarked name TRIAD to describe the technology, which allows consumers to use one coaxial cable to receive all HD channels from three different satellite locations. The system converts one of the 950 to 1450 MHz satellite bands to 1650 to 2150 MHz and another to 258 to 813 MHz, allowing the one standard L-band signal and the two converted signals to coexist on one coax.

"The block conversion limits of Triple Stacked TRIAD Technology of 950 to
2150 MHz is important," said Bob Howell, director of the Signal Distribution/Off-Air Antenna Business Group at Winegard. "The only alternative currently on the market today for triple stacking operates up to 3 GHz, posing some technical challenges at this higher frequency range."

Howell said the higher the frequency used, the more susceptible it may be to RF interference and that passive components such as splitters, taps, and the like may not be easily obtained. He added that triple-stacked systems must be designed with bandwidth to include cable TV and off-air HDTV channels and that the TRIAD technology can accommodate it.

Howell did not explain how the system would handle UHF off-air channels, which fall in the same spectrum as the 258 to 813 MHz that indicated as being used for a downconverted satellite band.
