In Osh- awa, the recently completed service is expected to reach some 30,000 homes. Throughout Canada some 250,000 homes are connected to Cable TV. Cable television went into op- eration in Oshawa September 1966. "Bill" Leask, an official of the new company installing the ser- vice says Oshawa Cable TV ex- pects to have cable laid along every street in Oshawa by the end of 1968. By that time there will be about 250 miles of cable worth Cable TV gives better recep- tion, more channels and elimi- nates the need for a private an- tenna said Mr, Leask. The company has a commun- ity antenna on Prestonvale Rd. located five miles east of Osh- awa. Two 150 - foot towers fit- ted with separate antenna for each channel pick up the TV signals. Equipment at the communi- ty antenna then amplifies, fil- ters and feeds the signals into the cable for the journey into town. Located at 4,000 - foot inter- vals are boosters to maintain the signal at even strength. In the city these amplifiers are spaced about 2,000 feet apart. The Cable is installed for Osh- awa Cable TV by Bell Tele- phone. The company also pays Bell for the use of their poles. About 40 Bell employees and subcontractors are currently en- gaged in installing cable.

Second Century Exciting for Cable TV Canada's Second Century will see CABLE T.V. blossom into the great medium it is for our homes, schools and community as a whole. Cities of the future will have no overhead hydro wires, telephone wires or 7V aerials. There will be a common trench down your lot line in which all services will be buried, including coaxial T.V. Cable. Cable T.V. will be a valuable teaching aid; educational programs will be originated in a central studio and relayed through the school system. CABLE T.V. will carry prize fights, hockey and football games, first run movies, will be available in the home via circuit T.V. Cable T.V. will provide a network whereby you may do your weekly shopping from your own living room via a closed circuit cable network, linked with your local supermarkets. As cities grow so does interference problems caused by vehicular traffic and industry. These problems are wiped out with CABLE TV. CABLE T.V. will play a very important part in Canada's Second Century. Look to CABLE T.V. AS MODERN AS THE SPACE AGE. THE SECOND CENTURY WILL SEE In the years between 1867 and 1967 we have seen the greatest 'advancement of mankind in all our history. We have seen electricity, the automobile, airplanes, rockets, the conquest of space, radio and of course the single most influen- cial force on our children and ourselves TELEVISION, In television we have seen it develope from its infancy to the present highly sophisticated form of today. All these are now obsolete, we will enter the second Century with CABLE T.V. The company was set up by channel, How It How It Bill Jones loves the excite- friends, his family and his fellow townspeople. Yet ex- local businessmen, Bill's town might not have TV. When television started, sta- tions developed first in big cities where they reached a large population. But in vast areas of the country people got poor pictures or none at all. Without a local station, Bill Jones must get his TV from a station in some nearby city. But many communities are in mountain valleys or far away from a TV station and cannot get a good reception. During 1949, TV did come to a town located far from a tele- vision station. Eager to bring the benefits of television to As- toria, Oregon, a group of en- gineers found a solution that would please Bill Jones. Their solution was a community-wide master antenna system. In the following year another group of enterprising men wor- ked out a similar solution for two Pennsylvania towns. Quick- ly and dramatically, using a master antenna system, Com- munity Antenna Television (C- ATV for short) sprang to Jife and to the rescue of Bill Jones and his TV-less community. Basically, the CATV system uses a giant (or master) an- tenna to receive normally weak signals. Each subscriber has|is his own set connected to the SO! using a home antenna. CATV is not pay TV. Injon purchase programs individual- ly on a pay - as - you see basis. In CATV you pay for the convenience of being con-| as ter antenna. Clearly, CATV is not a program service as is pay-TV. CATV systems have managed to bring their unique éervice CABLE TV: ment and fun of TV as do his cept for some _ far - sighted feet, reach the strong signals. Started Works to the public at modest prices. Using CATV, you do not need to put up your own expensive rooftop antenna. As a result there is no danger from wind- storms or lightning damage. A few points about TV signals must be explained to under- stand why CATV systems fill a unique position in the com- munities. Radio signals tend to follow the curvature of the earth. As a result they can be heard easily over great dis- tances. Not so television sig- nals. Television signals travel in a Straight line as does a beam of light. After broadcast, the signals continue into space as the earth's surface curves and falls away underneath them. Mountains can block - out TV signals and wreck your recep- tion. TV set owners in a valley surrounded by mountains fre- quently cannot get a good pic- ture. The farther you are from a TV station, the more trouble- some and expensive become your reception problems. Ordi- nary housetop antennas in this "fringe area are frequently un- satisfactory. They do not reach high enough. By placing specially design- ed antennas on a high tower, metimes built as high as 750 the CATV system can Yet "fringe" area reception only one of the problems solved by CATV. Problems of master antenna cable instead of| reception in valleys are solved by placing the master antenna top of one of the surrounding pay TV you are expected to! mountains. The CATV operator his town with the best TV re- ception on as many channels serves possible. To do this, the pro- per antenna location must be found. The CATV operator is able to search, with electronic instruments, for the place near town where master antenna re- ception is best. In this manner all subscribers receive pictures from the best receiving point. Sometimes the best antenna location is far away, Then oper- ators frequently rent an expen- sive, long distance microwave service to bring the signals to town, Even the design of the mas- ter antenna itself is of special electronic design suited to the CATV operator needs. As a pro- fessional, he skilfully uses equip- ment which has been special- ly designed, it is much too complicated and expensive for the average home owner. A sep- arate antenna, _ electronically tested for peak reception on each channel received, is point- ed toward each TV station. But the master antenna is only a part of the costly elect- ronic gear that makes up a CATV system. The CATV cable route through town also must be specially designed with professional care and expert electronic skill. Equipment at the master an- tenna strenghtens the signal and feeds it into miles of a special cable. The cable is cov- ered with costly protective ma- terials to prevent electrical in- terference. Some systems use as much as 200 miles of cable alone. These cables, known as coaxial cables, are usually at- tached to electric power or utility company poles. The CATV operator supplies the ca- ble and rents the use of the poles. Some CATV operators must cross very rugged country to serve their subscribers. The CATV operator makes sure the signal remains strong on its 'journey through town. Without -aerial 'amplifier' equipment the TV signal would become weaker and weaker the farther it travelled along the coaxial cable. Just as a long distant pipeline needs many pumping stations, so a CATV system needs many '"amplifi- ers" along the cable. The sub- scriber living farthest from the master antenna then gets a strong, even signal.
