58 -- ANTENNAS & INSTALLATIONS SOL N00178-98-Q-0045 DUE 091898 POC Roberta C. Moss, Code Sd18, 540-653-4304 or G.G. Scott, Code SD18, 540-653-4104 E-MAIL: Naval Surface Warfare Center, Dahlgren Division, mossrc@nswc.navy.mil. The Naval Surface Warfare Center, Dahlgren Division, Dahlgren, VA shall use Simplified Acquisition Procedures to procure on a sole-source basis, five (5) Large Aperture Antennas for Telemetry Tracking Applications, and their installation at various sites, from Electro Magnetic Processes, Inc., 20360 Plummer Street, Chatsworth, California. These antenna systems use EMP's Antenna Control Unit Model ACU-21C and EMP's Model 050 dual axis, single drive, elevation over azimuth pedestal. Antenna #1 shall be installed at NSWCDD, reinstalled at CSEDS, and then reinstalled onboard the ALI test ship at PMRF in Hawaii (3 installations); Antenna #2 will be installed at CSEDS, and then reinstalled onboard the ALI test ship at PMRF in Hawaii (2 installations); Antenna #3 will be installed on the PMRF off-axis platform in Hawaii (1 installation); Antenna #4 will be installed on the PMRF off-axis platform in Hawaii (1 installation); and Antenna #5 will be installed on the BLK-IVA LINEBACKER test ship (1 installation) for a total of eight (8) installations. Each antenna system shall include a radome-protected antenna, antenna control unit, environmental control unit, semi-rigid coax cables, a power cable and an antenna control cable. The systems shall be able to automatically receive and track simultaneous vertical and horizontal linear or right and left handed circular polarized signals radiated by missiles. They shall be able to provide direct track and auto track modes of operation. They shall be able to track outbound surface to air and ballistic missile interceptor missiles. They shall have the capability to keep pointed to a computed bearing, eliminating effects of ship motion while awaiting the missile's emergence from earth curvature blockage. They shall contain bandpass filters to provide protection from out-of-band shipboard emitters. They shall have front mounted controls to include the minimum: Azimuth Position, Elevation Position, Antenna Beam Selected, Operating Mode, Signal Strength Indication, Servo Error Signal Indication, Antenna System Power On, Antenna/Pedestal Control, AGC Voltage -- Digital controls and indicators are acceptable. Synchro-Mechanical Accuracy plus/minus 1 degree maximum. Weight shall not exceed 70 pounds. Physical size shall not exceed 8.75H x 16.62W x 20.31D. The basis for the sole source is because EMP designed and built the units required for NSWCDD. EMP personnel are required to ensure proper installation and training as required by this statement of work because of their knowledge and expertise. Installation is required immediately upon manufacture and delivery of the units. EMP can complete the requirement expediously, which will save the program from slipping it's schedule. Each installation shall include physical installation and alignment, electrical hook-up between the antenna and EMP's Antenna Control Unit (Model ACU-21C), checkout of operation, and training of the unit by the EMP engineer to ensure proper installation and use of the antennas. Completion of this requirement shall be by 31 January 1999. There shall be no written soliciation issued as a result of this notice. Closing date for submission of bids shall be on or before 18 September 1998 COB. Award to be made on or before 30 September 1998. Reference NSWCDD quotation N00178-98-Q-0045.
