      Tom,
       
      I had the opportunity to spend a one year ADSW (Active Duty - Special Work) at Key West when it was still JIATF-East.  The antennas you refer to were, indeed, for the purposes of "looking in" on Cuba.  The FBIS had a facility on site which they used to monitor and record Cuban Radio & TV broadcasts, along with other "special interest" programming.  You'll note that the antenna arrangements consist of a number of paired antennas with a total of, if I remember correctly, six sets.  With each pair, one is angled downward while the other is angled upward.  This was to ensure a satisfactory "look angle" as the F layer changed from day to night.  You may draw your own conclusions as to any other signals that were being snatched given the larger CN (Counter Narcotics) mission being carried out by other folks.

      Also, anyone know the purpose of the numerous UHF-TV looking receive antennae on the big self supporting tower in the back of the JTF compound at the NAS Key West site adjacent to Truman Annex? Same with the four vertically polarized log periodic antennae? We're heading down there in a couple weeks....

      I've been there and noticed them too.

      Havana is 90 miles across the water, therefore I would suggest that those antennas are log periodics to pick all sorts of radio signals.
      For the UHF+ frequencies they might have a ship anchored outside the 12 mile limit with receivers which are then upconverted to other freqs for the final hop. Just conjecture on my part.
