In a review of the system in a recent issue of the Bell Telephone News, it was pointed out each of the 107 stations from New York to San Francisco features four ten-foot square horn-shaped antennas, for receiving and transmitting. High-gain amplifiers at each station were noted as being used to boost signals a million-fold. One of the most unusual relay points was cited as being at Creston, Wyoming, where the relay station was located in a gully. The antennas, set to face east, were mounted on a 25-foot tower so as to just peek over a ridge of the Continental Divide, thereby minimizing troublesome signal reflections from the valley below. A separate 75-foot structure was installed to hold the westward operating antennas high enough to provide a clear line-of-sight to the next relay point at Bitter Creek, Wyoming. In Utah, the review stated, the microwave takes the old Mormon route through Pratts Pass as it approaches the Great Salt Lake. West of Salt Lake City, the engineers adopted an unusual procedure to overcome excess interference caused by radio-wave reflections from the famed Utah salt flats. The technique was to direct the microwave beams from a high station near Salt Lake City to a ground level station 38 miles to the west in the flats. From this point, the signals can take a 20-mile jump to Cedar Mountain, which rises above the flats, then jump 32 miles to a second ground level station and finally back to high ground again in another 32-mile leap to Wendover, just across the Utah-Nevada border. Thus, the path of the beam was said to form a huge W, 122 miles wide.
The East Bay Hills relay station, just outside of Oakland, California, was selected as the point of interconnection with the existing San Francisco-Los Angeles microwave route. A short microwave jump across the bay was noted as serving to carry the signal into San Francisco.
