Chapter 3. Coaxial Cable > Cable TV Channel Allocation Scheme

3.5. Cable TV Channel Allocation Scheme

The in-house coaxial cable wiring carries many channels of TV signals. The conventional TV VHF channels, channels 2 to 13, occupy frequencies from 54 to 216 MHz with frequency gaps in between for FM broadcast stations. The off-the-air UHF channels, channels 14 to 69, occupy frequencies from 470 to 806 MHz. Table 3.4 shows frequency arrangement for off-the-air TV channels.

This TV channel frequency arrangement is regulated by Part 73 (Radio Broadcast Services) of FCC rules and regulations, which is labeled as CFR title 47 [1]. Channel 37, occupying 608 to 614 MHz, is reserved exclusively for the radio astronomy service. Many off-the-air digital TV channels have been allocated in the UHF frequency band for the analog-to-digital transition period. Detailed information, including location and channel numbers, can also be found in the recent Part 73 document.
