Applications

The Transat 2M7 dates from the early-to-mid 1980s, the pioneering era of home and commercial C-band TVRO (Television Receive Only) satellite reception in the United States. Before cable and direct-broadcast satellite (DBS/DirecTV) became dominant in the late 1980s and 1990s, C-band dish systems — typically 6- to 12-foot backyard parabolic dishes — were how enthusiasts, rural homes, hotels, and broadcast facilities received dozens of unscrambled satellite feeds directly from the birds. The receiver sat at the heart of this system, taking the downconverted signal from the LNB/LNA on the dish and selecting individual transponder channels. Transat Microwave Systems was one of several American manufacturers producing dedicated C-band receivers during this period. Today, the Transat 2M7 is primarily of interest to vintage TVRO collectors, satellite hobbyists, and retro-technology enthusiasts. It may also find use in educational or museum settings illustrating the history of satellite television.
