Show cornucopia antenna." Mr. Simmon said. Ho went on to say the cornucopia cornu-copia antenna i the latest in design by the Bell Laboratoriea and resemble re-semble a horn of plenty. The existing ex-isting system and the TH system will use the aame antennas which are designed to receive and transmit trans-mit in several super high frequency band simultaneously. The TH operates op-erates in the higher band. At present, six TV and four long distance message channels- each capable of carrying a television program or 600 voice conversations conversa-tions in one direction are provided pro-vided on the original route. Initially the TH will add one television and two voice carrying channels. Both system will include two channels for standby use in case they are needed to keep service operating. O Mr. Simmons said that when the work ia completed next year, the Salt Lake City-Denver route will be carrying two separate radio relay systems. The original system was installed in 1951, end is of the type that provides more than 30 per cent of the nearly 63 million miles of long distance circuit making up the Bell System's nationwide communications com-munications network. The new system, sys-tem, called "TH", i capable of carrying almost four times as many voice conversations. The long line department of the American Telephone and Telegraph Co. i coordinating the modification work at the 16 intermediate point where antenna-topped tower and equipment are provided along the route. "The first phase of reconstruction reconstruc-tion involves modifying relay towers tow-ers and equipment and making a change in the giant radio antennas now in use to a type known as the REVAMPING JOB BEGINS ON RADIO RELAY ROUTE BY PHONE COMPANY A major revamping job began April I, on the' radio relay route between Salt Lake City and Denver, according to DeWayne W. Simmons, Sim-mons, manager of the Mountain States Telephone and Telegraph Co. Three of the intermediate relaying re-laying stations are in Utah. The 500-mile .route will be the nation's first to be equipped to carry the Bell System's latest de- sign in radio relay systems. The new system to be installed can operate op-erate over existing routes without interference to the original system in operation, and can, at full capacity, ca-pacity, add more than I 1,000 simul taneou voice conversations to the communications super highway. |
