Why did cable companies implement microwave technology?

• A. To improve picture clarity
• B. To reduce service costs
• C. To deliver broadband internet
• D. To fill vacant channel spaces with distant stations

Answer: (D)

Microwave technology acts as a fast, line-of-sight way to transport TV signals over long distances. By using relay towers to receive and rebroadcast distant broadcasts at the headend, cable systems could add channels that weren’t available locally. This effectively fills the lineup with content from far-away stations, expanding what subscribers could watch. In the early days of cable, bringing in these distant signals was a primary reason to use microwave links, before other distribution methods became widespread. While picture quality, costs, or later internet needs are considerations in other contexts, the key purpose here was to broaden the channel lineup by accessing distant stations.
