|37820 The Tower and Aerial of a Television
This tower is 300 feet high. It is placed on a hill that is 1,700 feet high so that buildings will not hinder the television waves on their way to television receiver aerials.
The aerial, at the top, looks like canoe paddles and pipes. This is the best shape for use with television waves. The "pipes," which come out of the building and go up the tower, are feeder wires. They take the television waves from the powerful television transmitter up to the areial. These feeder wires are as big around as is a broom handle.
On the outside television transmitters look very much like regular radio transmitters. The difference is in the tubes, coils and other parts, which are a special type for television, frequency modulation, and other very, very high frequency broadcasting.
