It probably was-----note the country of Origin: Japan. This was made in the time period before Chinese and South Korean manufacturing threatened our domestic electronics manufacturers. Japan was at the top of quality ratings back in those days (satellite equipment made by Toshiba, Panasonic, Uniden and others), and gave our receiver and LNA/LNB manufacturers some serious competition. Cal Amp and Drake survived over the long term domestically, but you rarely heard about Avantek and Amplica after a certain point. Bob must have found a converter device that worked well for his receivers. It took a while for our last standard of 950-1450 MHz IFs to actually become the standard, and the Japanese drove that standard, while we had 930-1430 (STS), 270-770 (Scientific Atlanta) and 430-930 (Locom and Anderson Scientific). Those that chose 950-1450 MHz as their conversion scheme stayed in business longer than others using the others. (930-1430 was cheap and dirty for STS, 430-930 used modified UHF tuners for lower cost product, and S-A was in a league of their own with their 270-770 MHz standard, with much higher prices).
At one time you could buy higher quality versions of all of the above, made by California Amplifier, which did very well in the 1980s and 1990s, selling C-band devices.
