CONSTRUCTION Test Command furnished items are as follows: high Log Periodic IJonospheric antennas; and, contractor will furnish two 20 kw, a) two 110-ft. b) one instrument traile r. 120/240 volt, 60 cycle, The single phase, low speed (1250 rpm) diesel generators. One of the generators is utilized asa back up power source. In the event local power 1s available. only back up power is required. The contractor will perform the following: a) prepare a cleared, flat, 355 x 515ft. unobstructed area for the TC erected 110-tft. high Log Periodic Ion ospheric antennas which will have a ground screen that extends concrete antenna bases, as designed by TC in the field; pads and anchors for the antennas; into the sea; b) construct c) provide lon geron d) site the instrument trailer; and, e) install the generators if local power is not available, and complete the electrical hookup to the instrument trailer. The site location will be selected after a re connais sance by the project officer. Six scientific personnel will be assigned to Subtask A6oll at this site. 30-1 VOL II April 1969 =
