DF-301E V/UHF Direction Finder

The V/UHF automatic DF-301E from Rockwell Collins is a single unit, lightweight, airborne radio Direction Finder (DF) that gives you continuous indication, in degrees, of the relative direction of arrival of voice modulated, tone modulated or crew workstation signal in the RF band 100 to 400 MHz.

The electronically rotated antenna permits the use of microelectronics to their best advantage, lowering power requirements and heat generation. The result is a concept in DF systems that gives you greater reliability and improved performance. The bearing output of the DF-301E is a standard synchro output.
