KAUAI, AEC-TRF SCIENTIFIC 11019 Page 2 Two (2) radar antennas are provided; antenna J-1 is located 50-ft. north of the trailer dock, and antenna J-2 is located 50-ft. south of the trailer dock. An above-grade cable tray system conveys signal cable from the Radar Control Trailer to each antenna. A radar target pole is located approximately 2,100-ft. north of the trailer dock, Balloon Release Station No. 1 (Building 664) is located 850-ft. southeast of the trailer dock and Balloon Release Station No. 2 (Building 651) is located 850-ft. northwest of the trailer dock. Each balloon release building is a 12 1/2 x 13 x 12-ft. high, wood framed structure with a concrete floor slab. Three (3) sides of each building are sided with plywood and the fourth side is provided with roll up canvas siding. Floodlights provide exterior illumination. The buildings are equipped with a helium manifold system anda helium cylinder bank. A 50-ft. balloon release pole is located 15-ft. from each building. The poles are equipped witha ''Flagpole'' type system for raising and automatically releasing inflated balloons varying in diameter from 2 to 6-ft. Each balloon release build- ing has apowerdemandof5kw. The balance of the Rawidar Complex requires 10 kw of utility power and 30 kw for scientific power. The source of power to the Rawidar trailer dock is a power panel at the main trailer dock. Incoming 600 volt, 60 cycle , 3 phase power is converted to 400 cycle power by a combination generator/convertor unit. An engine driven 30 kw generator provides back up power in the event of commercial power failure; transfer to back up power is accomplished manually. FY 1969 ENGINEERING Completed. Drawings: JS 97-058-A5 PROCUREMENT 110-077-SK-W1 In progress. CONSTRUCTION An 8 x 20 x 7-ft. high wood framed shelter will be constructed for the generator/converter unit. The structure will have a concrete floor slab and plywood siding and roofing. A personnel door and a pair of folding doors will be provided. The folding doors will provide a 7 x 8-ft. opening. In order to coordinate the balloon release and tracking operations, a VHF net consisting of a base station and three (3) hand-held transceivers will be provided for the Rawidar Complex (refer to F&S No. 11-15 13002}.
