The measurements were made to determine the performance of twelve UHF antennas used for TV reception. Though all antennas tested were designed for multiband operation, the antennas tested covered, inter alia, the frequency range of TV channels 40 to 60 for 8 MHz channel plans and TV channels 41 to 65 for 7 MHz plans.
Analog television system by nation. International broadcasting television frequencies are divided in two part of the spectrum; the Very high frequency or "VHF“ band and the Ultra high frequency or "UHF“ band.
18 Δεκ 2021 · The analog video and analog audio carrier frequencies listed in the table below are for NTSC analog TV and are not applicable to ATSC digital TV (DTV or HDTV). Some analog TV stations were offset + or - 10 kHz (0.01 MHz) from the standard frequencies to reduce co-channel interference.
3 Οκτ 2024 · The formula for converting a TV channel number to its corresponding frequency band varies depending on the channel number. This conversion is based on predefined allocations which segment the TV broadcast spectrum into channels and assign a specific frequency range to each channel.
UHF (TV) & VHF (FM & DAB) frequency wavelengths. Wavelength = Velocity ÷ Frequency. Speed of light = 299,792,458 m/s. To calculate the wavelength (in cms) divide 30,000 by the frequency (in MHz). This should be accurate to 0.07%, which is accurate enough for most RF applications...
practical aspects of VHF and UHF antennas, recommends 1 that the formulae contained in Part 1 of Annex 1 and the associated computer programs described in Part 3 of Annex 1 should be used to evaluate VHF and UHF antenna systems performances for planning purposes;
