CATV HFC Basic（英文版）内容提要：
Television Signals：
Originally, Television signals were only available as broadcasts from antennas located atop towers near large cities.
The typical broadcast could only be received within 15 to 50 miles of the transmitter, and if there were hills, valleys or
other obstructions, the signal was disrupted.
Very few channels existed.  The typical viewing area received less than five channels.
To watch your favorite Saturday Night Program, it usually involved multiple adjustments to your roof mounted antenna system.
Milton Jerrold Shapp：
Milton Jerrold Shapp, former governor of Pennsylvania, returned home from the service.
He vacationed at his family home in the Pocono mountains of Pennsylvania and was unable to receive television signals from either the Philadelphia or New York region.
Shapp had a friend who worked as an RF engineer at the Philco Radio plant on Fox Street in Philadelphia. The two decided to erect a large antenna on top of the highest mountain in his Pocono village.
