CONSTRUCTION The Radiometer Station will occupy a stabilized area 140 x 170-ft. on the southeast side of J.I, near the POL storage area. A 15-ft. diameter octagonally shaped reinforced concrete pad 2 1/2-ft. thick will be constructed to support a 30-ft. diameter steerable antenna. Two mobile TC furnished antennas (8 x 22-ft.) and two TC furnished instrument vans (8 x 40-ft.) will be located within the stabilized area. Four copper-clad steel grounding rods, 5/8-in. diameter x 8-ft. long, will be placed ina 10-ft. diameter circle near the center of the station. From the station, a clear line-of-sight must be pro- vided to subtend an angle of 15 degrees to each side of all events and to allow an unrestricted view down to 3 degrees above the horizon. Approximately 30 kva of 120/208 volts, 60 cycle, 3 phase power will be provided to the two instrument vans. VOLI April 1969 1-64 Sa|
