The Iroquois class is discussed elsehere in this web page ( RADIO FITS OF THE MID 1980's - Intro) so only information about the antennas is provided here.
This montage of antennas circa 2001 is intended to show the various radio systems aboard the Iroquois 280 class at the time and also shows the minimum safe distance for those antennas which emit RF. Click to enlarge. This summary diagram was on display during an open house at FMF Cape Scott on August 5, 2007. (Photo by Sandy McClearn)
