Radio systems generally require antennas with lengths of a certain size compared to the wavelength being used, so in the case of the SCR-268's ~ 1.5 metre wavelength (205 MHz), the antenna was an extremely large system that presented serious logistics problems.
Radio systems generally require antennas with lengths proportional to the wavelength being used, and thus inversely proportional to the frequency used. So in the case of the SCR-268's ~ 1.5 metre wavelength (205 MHz), the antenna was an extremely large system that presented serious logistics problems.
