CHAPTER II, SECTION 3 STATION: PURPOSE: 1321 Collimating Baffle for Remote Alpha Detector SITE: Dog USER: LASL PARTICIPATION: 10, 11, 12 and 13 CONSTRUCTION: 2-15-56/5-4-56 OCCUPANCY: 4-14-56 Station 1321 was a heavy reinforced concrete wall located 75 feet forward of Station 1320. The concrete wall was supported by 12inch H-piles and protected from wave action by sheet piling. Holes, with steel cover plates located in the wall, served as a line of sight from the pipe collimators in Station 1320 to the zero locations of the barges. This wall was required to withstand all of the Bikini events. Existing CASTLE Station 1211 was demolished prior to the construction of this station. A total of 138 cubic yards of concrete was poured with an average 28-day strength of 3,800 psi. STATION: PURPOSE: 1331 VHF Dish Antenna USER: DOD-13 SITE: Nan PARTICIPATION: 18 Station 1331 was a 10-foot-diameter dishtype antenna mounted at the 50-foot level of the Station 70 tower. Styroflex cables 7% inch in diameter extended from the antenna to room 18 in Station 70. STATION: PURPOSE: SITE: 1332 VHF Dish Antenna Nan USER: DOD.-13 PARTICIPATION: 10, 12, 13 and 22 This station was a 10-foot-diameter dishtype antenna mounted at the 105-foot level of the Station 70 tower. A wave guide and 7% inch Stryoflex cable extended from the antenna to Room 18 of Station 70. STATIONS: PURPOSE: SITE: 1333.01 thru 1333.03 Horn-Type Antennas Off Dog, on Barge Stations 10, 12 and 13 USER: DOD-13 PARTICIPATION: 10, 12 and 13 Figure 2-77. Station 1321 -66% Complete These stations were horn-type antennas mounted on top of the barge cabs. Coaxial cable extended from the antenna to the barge zero location. Power in the amount of 1 KW, 120volt, single-phase was supplied from the barge station generators. Timing signals of minus 45 minutes and minus 15 minutes were required. STATIONS: STATION: PURPOSE: SITE: USER: PARTICIPATION: 1330 VHF Dish Antenna Elmer DOD-13 All Eniwetok Events Except Osage Station 1330 consisted of a 10-foot-diameter dish-type antenna mounted at the 92-foot level of CASTLE Tower 1301, and twotrailers located at the base of the station. Styroflex cable %-inch in diameter connected the antenna and to onetrailer. One 40 KW generator was User-supplied and 20 KW, 3-phase, 120/ 208 volt stand-by power from the island distribution system was provided for each trailer. Four timing signals and a telephone with extension were installed for one of the trailers. All equipment was User-furnished. Page 2-90 PURPOSE: SITES: 1334.01 thru 1334.09 Parabolic Antennas Various USER: DOD-13 PARTICIPATION: 1, 2, 3, 4, 6, 7, 22 and 24 This series of stations consisted of 5’ x 6’ User-furnished parabolic antennas mounted on the outside of the various zero stations. Power requirements consisted of 1 KW, 120-volt, singlephase and were obtained from each individual zero station power supply. Timing signals of minus 45 minutes and 15 minutes were required.
