This tool calculates the best interference-free radio frequencies (UHF) within a TV channel (8 MHz grid). Only one TV channel is analyzed in isolation. Additional frequencies from other TV channels are **not** checked for compatibility. | This tool calculates the best interference-free radio frequencies (UHF) within a TV channel (8 MHz grid).

The minimum requirements for intermodulation resistance are met in all cases. These values apply to the increasing frequency intervals. The order must be reversed for the descending frequency intervals. | The minimum requirements for intermodulation resistance are met in all cases.
