Test Command furnished items are as follows: a) one 110-ft. high Log Periodic Ionospheric antennas; and, b) one instrument trailer. If local power is not available two 20 kw, 120/240 volt, 60 cycle, single phase, low speed (1250 rpm) diesel generators are required. One of the generators is utilized as a back up power source. The Navy Public Works Department will perform the following: cleared, flat, a) prepare a 310 x 320-ft. unobstructed area for the TC erected ]10-ft. high Log Periodic lonospheric antennas which will have a ground screen that extends into the sea; b) construct concrete antenna bases, as designed by TC in the field; c) provide longeron pads and anchors for the antennas; d) site the instrument trailer; and, e) install the generators and complete the elec-~ trical hookup to the instrument trailer. Refer to Figure A-21, Appendix A, The four scientific personnel assigned to Subtask A6)]) will also operate the Subtask A628 facility at this location. for site location. 24-7 VOL II April 1969
