59 -- ACQUISITION AND INSTALLATION OF A 10,000 WATT TRANSMIT ANTENNA MATRIX POC Contract: Linda Mullen, (202) 267-1512, Contracting Officer, Jerome Hensley, (202) 267-6211 The U.S. Coast Guard (USCG) intends to award a sole source contract to Delta Electronics, Inc., Alexandria, VA 22312, for acquisition and installation of a 10,000 Watt Antenna Matrix at USCG CAMSPAC, Point Reyes, CA. The matrix shall operate in the high-frequency range of 2-30 MHz. The matrix shall be remotely controllable and shall be interfaced to the USCG's existing Communication Station Control System. The USCG currently owns a total of 6 high-power transmit antenna matrices of this type. Delta Electronics will provide a commercial, off-the-shelf, remotely controlled antenna matrix switch with 24 transmitter inputs and 30 antenna outputs (20 of the transmitter inputs will be populated with crossovers and 4 of them will be left unpopulated). A key controlled "lock out row" is also required; provide service to overhaul two Delta Electronic's MCU-8 controllers presently being used to control the antenna matrix now installed at CAMSPAC; de-install the existing CAMSPAC matrix switch and install the new matrix switch and overhauled controllers at CAMSPAC; install contractor provided Polyphaser lightning arresting units in the antenna output lines just before they exit the building; combine all Polyphaser ground points and silver solder to the station ground system; install 10 contractor supplied Bird Corp. 4715-000 line sections and 10 government supplied Bird Corp. 4715-000 line sections in all transmitter line inputs on top of the new matrix switch; acquire and install Bird Corp. elements 1000H12 and 10KH12 for all line sections; install a government supplied Voltage Standing Wave ratio (VSWR) master signal switch in a 19" rack space designated by on-site Coast Guard personnel; install contractor provided Bird Corp. Model 3127-040 wattmeter in the 19" rack space designated by on-site Coast Guard personnel; and shall connect the wattmeter input to the output of the VSWR master signal switch. Delta Electronics, Inc., is the only known source available to provide the Delta transmit antenna matrix. While theremay be more, it would not be cost effective to purchase and support a different matrix system than the 6 Delta matrices currently owned by the USCG. It is not feasible to compete with any other source. Questions concerning this notice may be directed to Linda Mullen at (202) 267-1512. See Note 22.***** (0168)
