What frequencies were used by early television broadcasters?

Answer 1

Frequency is frequency. I don't believe the earlier TVs could get away with using less frequency than modern TV sets do. You need a certain frequency of light to create 30 frames per second on the TV, so that the motion picture isn't jerky or speeded up.

TV signals are in the 54 MHz to 60 MHz range. Within this 6 MHz space is a video carrier, a color carrier, and an audio carrier.

Just my opinion. I did not research it very much.

Answer 2

VHF Very High Frequencies 30 - 300 MHz
UHF Ultra High Frequencies 0.3 - 3 GHz

These were the radio frequencies used by broadcasting television stations. UHF was the more common one used in the early 70's to late 90's.

I hope this answers your question.

Answer 3

The same ones in use today (including a now defunct channel 1 - which was eliminated to accomodate FM radio, that's why TV's start with channel 2)
