While 5000 kW is the maximum power for UHF NTSC stations, less than a fifth of licensed stations use that level of power; in Washington, D.C., for example, the powers used by four UHF stations range from 2450 kW to 5000 kW. The maximum power permitted PCS licensees in the 900 MHz bands, in contrast, is
