>If one visits Oahu the opportunity to see another one does exist (probably easier to talk the XYL into a trip to HAWAII).   I did some work with the US Army on Oahu a few years back and did see the installation from a distance.  Its located in the NE corner of grid BL01xm, or -158.01135W, 21.52228N.  I used this map site to get the location info:       http://f6fvy.free.fr/qthLocator/fullScreen.php

>The James Bamford book on NSA "Body of Secrets" has many references to Elephant Cage rx arrays.
