Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

toward Intercontinental TV An important advance has been made in microwave radio! It's called "over-thehorizon" transmission. Until recently, microwave was limited to line-of-sight distances, signals being beamed directly from one antenna right at another. However, engineers knew that a small part of the signal "drops off" the beam, or is "scattered" in the troposphere. A whole new concept was visualized, requiring new, specially-designed equipment. Now, with the new technique, the signal is beamed far out over the horizon with tremendous power. Huge new "highgain" antennas capture the "scatter," and a special IT&T electronic system keeps the signal steady for highly reliable communications. Thus "over-the-horizon" transmission promises to span truly long distances . . . a big step toward the day when TV may cross the oceans. For telephone and telegraph, facsimile, and telemetering, great benefits can be made available today. IT&T engineers were the first to introduce microwave communications, 25 years ago. And, by the development of unique equipment, they have made a major contribution toward making "over-the-horizon" microwave commercially practicable. ■ "■VI" INTERNATIONAL TELEPHONE AND TELEGRAPH CORPORATION, 67 Broad Street, New York 4, N.
